Half-Life: Opposing Force

The Good
One of the great dreams of computer entertainment software was the ability to tell the same story from completely different viewpoints. Few games (or otherwise) have truly attempted such (the interactive fiction piece 'Madness of Roland' is one of the few to come to mind). Half-Life:Opposing Forces (HL:OPFOR) does this very thing - in a first person shooter environment of all things. And it does it well.

In the original Half-Life, you played Gordon Freeman, a scientist caught up in the catastrophe at the Black Mesa research labs. Your first goal was to make it out alive, which was hampered by the introduction of a U.S.M.C. detachment sent in to clean up the mess...including Freeman. In Opposing Forces, you play one of those Marines and get to experience the same timeline all over again, from another point of view. Although you rarely tread the exact same ground, the team did a wonderful job of making you feel like you 'just on the other side of wall' from the previous games events. Freeman even makes a quick visual cameo (he's mentioned a few times as well) and players from the first game almost find yourself rooting for him out of memories. Sympathies develop for the Marines you might have feared/loathed in the original and hatred for the manipulative man in black continues to grow. The experience makes the world of the first game come alive and truly seem three dimensional.

As you play a military man and not a scientist, you would assume that the game would emphasize combat and it does this well. You have squadmates with various skills whom you'll utilize in various situations. Although they don't seem to have the determined team work of the leathernecks you faced as Freeman, your fellow Marines will often play smart (although usually outgunned) and are a little more effective than the 'extra firepower' the guards provided Freeman in the first one. The array of weaponry has been increased as well, although many have subtle differences as opposed to the dramatic variants first person shooter fans may seek. Surprises and trying to gain the tactical high ground make their way into the action.

The emphasis on combat lessens the reliance on jumping puzzles and such. You are required to make some fantastic leaps, but compared to the first game, they're both considerably less and much easier. Your trips to Xan are rare and mostly self-inflicted, so you can avoid the low gravity platform leaps in an alien environment that most people found distateful at the end of the original. It appears that Valve listened to their customers when designing OPFOR.

As in the original, a story carries the carnage as you race about the complex and is on par with Half-Life for its ability to tell the story through both short conversations and visual presentations. Few recent games have done so much with presenting a tale without going into lengthy cut-scenes or long diatribes. In Opposing Forces, Valve proves the talent they showed in Half-Life wasn't a fluke.

Although low in polygon count, the graphics in the game more than do their job in presenting the world around you. Games like Unreal may be prettier, but at times you may find yourself appreciating the way the Valve manages to capture the realism of an area. The base feels real and even though you can't explore the whole thing, between the wonderful architecture and little peaks they give, you get a feeling of there being a complete installation, instead of abstract, connected levels.

The Bad
Even though it's almost as long as the good, non-Xan parts of Half-Life, OPFOR feels much shorter. Granted, the timeline of this game needs to fit within the originals, and you don't arrive in that timeline until a third of the way in, but fans of the original will find themselves wanting more in the end. As OPFOR is an add-on, this is understandable on a logical level, but you can't help feeling like there should have been more.

It's nice to work with fellow Marines, but it's often frustrating that they deliberately force you to move on without them, either because you fall down some hole they can't follow, jump over some obstacle they can't, or they just stop moving up with you. In most cases, I assume the designers figured your buddies would've been killed off by these points, but if you're careful, you can keep them alive. Having them stop and mill around takes away both realism and the feel or truly operating with fellow grunts you want to keep alive. This happened in the original as well, but since your primary goal, as the only one in a suit, was to escape to get help, it made sense that you left people behind temporarily. Here it doesn't work as well.

The emphasis on combat can lead you to 'can't win' scenarios because you wasted ammo early on. While restoring battles isn't as frustrating as for jumping puzzles (and actually can be fun to try to tackle a situation differently, it can get tedious.

The final boss is more interesting than Half-Life's, but the ending is once again unfulfilling and ambiguous. This works for leading into a sequel and fits the mystery and uncertain mood of the tale, but most people like some closure and 'victory dance' for their final win, not an anti-climatic scene.

The Bottom Line
If you enjoyed Half-Life, you'll enjoy this variaton on the tale. See the Black Mesa facility from the viewpoint of the Marines you once feared and try to complete your mission and learn even more of the base's many mysteries. As you'll need Half-Life to play, you may want to play the former all the way through first, as the two games interlock on a grand level and compliment each other. Those who hated the jumping puzzles of the first game will be happy to note that the Corps. apparently doesn't train frogs.

The Good
Anyone who has already played Half-Life and jumped straight to Half-Life 2 probably have no idea that there were two add-on expansion packs. The first one of these add-ons is called Opposing Force, and it is by far the best one that I have played in the old HL era. Before writing up this review, I read two that are already on there and each one recapped what happened in the original game. All of them are summed it up quite nicely, so here is my version of what happened.

Gordon Freeman is a scientist working at Black Mesa Research Facility, and his first task is to get to the Anomalous Materials lab and push a specimen into the scanning beam for analysis. This causes a portal to open between Earth and an alien planet called Xen. After this, Freeman has to defend himself against several types of aliens that randomly teleport in from Xen. Later, he encounters HECU soldiers that have orders to contain the alien threat and silence all witnesses. One of these soldiers is Corp. Adrian Shephard, and it is he who you get to control in this game.

That's right. You become the enemy rather than a good guy, and that means you can shoot any scientists and security guards on sight. You may not be able to get in locked doors that require a retinal scan or a certain code to open, but who needs them anyway when you've got your own team of engineers and medics to get the job done for you?

Shephard has access to weapons a real soldier should have including knife, pistol, machine guns, trip lasers, and grenades. Later, he will be able to use more advanced, alien weaponry. Shepard can carry more in his arsenal than Freeman could. The weapons are divided into seven groups, so there is quite a variety to choose from. The alien weapons are much more interesting than those found in Half-Life, and I enjoyed playing with some of them. I had to use each one sparingly as ammo for these weapons are scarce.

The early chapters have Shephard fighting the same enemies that were present in Half-Life, but it is not until later in the game that you get to meet those dubbed “Race-X”. This alien race are a lot more aggressive than their other counterparts. They look excellent, especially in outside scenes. The only bosses in the game are huge and take more than just bullets to destroy. Like Half-Life, you have to fully explore areas looking for switches to push and valves to turn, that could possibly have an effect on the bosses. But using switches and valves are not just confined to bosses. More often than not, you need to push switches and move valves in order to get some machinery going or take you up to higher places, like you do in Half-Life. What's new in this game is the fact that you can access CB radios that can often be found on crates or on a shelf, and doing this will cause your captain to assign you with new tasks.

The environments in which the character walks through are rather nice. I like the way that you have the opportunity to revisit some of the locations that were in the original game, along with the gadgets that adorn each wall. Some of the hallways you walk through look futuristic, and one could be fooled for thinking that you are actually walking through one on board a space vessel. There are some underwater scenes where you walk through a building surrounded by underwater. There are windows all the way round, and you can see what creatures lurk on the other side, as well as the various debris and seaweed that has found its way there.

The soundtrack is well composed. Most of the tracks in the game have a military theme to them, and some of them reflect the situation that you are in. They are CDDA tracks so you can listen to your favorite ones outside the game

Before I started playing the game, I joined the Boot Camp, to see whether I would pick up some new skills. Most of the skills you learn there were previously taught back in Half-Life's Hazard Course. Some sections, however, have you perform tasks a real soldier accomplishes, including navigating vertical rope ladders and putting your new team to good use. The one thing I like about being in Boot Camp are the instructors themselves. If you go up to them and start hitting your Use key, they will hurl insults at you, calling you dirtbag or maggot in the process. Also, you can get them to take a hike just by having Shephard repeatedly bump into them.

The Bad
There are a few maneuvers that I found difficult performing:

Navigating a rope ladder is somewhat difficult. One section of the Boot Camp has your climbing one, then jumping to another. I tried this, but I kept on falling in brown water about ten times. You have to gather some momentum to perform the jumps properly. Outside Boot Camp, there are sections of the main game where using rope ladders is crucial to reaching a platform above you. I had difficulty in doing this, even if I climbed to the top.

I expected more from the barnacle gun, which is an alien weapon that you pick up later in the game. Unlike the ceiling ones that you frequently encounter in this game and in Half-Life - where the barnacle will suck you up to its jaws when you walk under it – the gun is only good for pulling Shephard to pods attached to a wall, in an attempt to get to a platform nearby. Again, this is difficult to do.

It was easy to get stuck in elevators when they arrive at another floor, and this usually happens if you stand on the edge of the elevator. I could only turn around and not go any further. I believe that this was a bug that has not been address by Gearbox.

In the end, I found that using the noclip cheat helped. I disable the cheat when I'm done with the maneuver.

Initial versions of the game require you to install Half-Life before installing the game, otherwise the installation would fail. Starting with Blue Shift, Sierra removed the requirement of installing original games before installing add-ons, which is quite a good thing.

The Bottom Line
In Opposing Force, you play Corp. Adrian Shephard rather than Gordon Freeman. You do the same tasks that you perform in the original game – killing aliens, flipping switches and turning valves to make things happen, and walking through beautiful locations (both inside and outside). There are a few differences: a) you have a bigger arsenal than Freeman's; b) a new, much stronger, more aggressive race of aliens scatter about the corridors to give Shephard a headache; and c) you can access CB radios sitting on crates or shelves which will give you new objectives. The graphics are beautiful, and the soundtrack is excellent.

Also, you can do anything you like when it comes to dealing with people. An example is where one of your team members hold the scientist at gunpoint. You have two options: do you watch him as he continues to trap the scientist inside a room, or be a traitor to your own team and shoot the soldier, releasing the scientist in the process. The best thing about these options is that you don't get punished for the choices you make. Just don't end up killing either the engineer or the medic.

I played the Steam version of Opposing Force and it works quite well. The soundtracks are comprised of MP3 files rather than CDDA tracks. I believe that a bug allows the game to play CDDA tracks whenever a MP3 is about to play, and I made a mistake of leaving my Grand Theft Auto: London 1969 CD, so instead of hearing the soundtrack, all I could hear was old '60s music. Thankfully, I still have the Opposing Force CD so I don't miss out on anything.

Bottom line: Opposing Force is an excellent add-on from Valve , and an add-on that is worth replaying. I hope that Valve will release a Source version of it, just like they did with the original.

The Good
The new weapons are very neat. The Displacer and the Barnacle don't see the use very often, but their concept is very nice and original. The new enemies are well thought-out, but it's a pity that they aren't as original as the weapons.

I really loved the level design. (A nice feature is being able to visit some of the areas you visited back in Half-Life!) The authors made great use of the HL engine, the puzzles are as good, if not better as in Half-Life. There are some new gameplay elements added: most interesting are the climbable ropes. They don't appear very often, but for a game made in 1999, their physics are good; you can even realistically swing Tarzan-style on them.

The graphics are quite good and the gameworld is as detailed as in Half-Life.

The "Black Ops" soldiers you fight in the game seem to be more intelligent than the soldiers you fought back in Half-Life. I always thought the HL soldiers' AI was a little overhyped, but the Black Ops appear to be really smart.

The Bad
After getting used to the HL's crowbar, the two melee weapons available in OF are a little inequal. The wrench is strong, but too slow; the knife is fast, but too weak.

The game is harder than Half-Life, mainly due to the new enemies (which are much stronger and more dangerous than their HL brethren), but also because there seem to be very little batteries or HEV chargers in the game, so your armor will be 0 most of the time - and when this is the case, the enemies' attacks are really harmful. Likely the most dangerous enemies are the Shock Troopers, who fire really fast and are hard to take down.

Controlling your soldier buddies can get tiresome at times. Sometimes they decide not to follow you for no particular reason and you have to uncontrol/control them several times.

An annoying bug is getting stuck in elevators. It happened a few times to me, and the only way is to reload the game and jump constantly while riding on the elevator.

The Bottom Line
But all in all, Opposing Force is an excellent expansion, and a worthy addition to the Half-Life universe. If you liked Half-Life but didn't yet play Opposing Force, do yourself a favor and return to Black Mesa as corporal Shephard.

The Good
I'm still bedazzled to see how this game was so spitted upon and said to be like a easy-to-earn on fame of Half-Life crap. This is not true! Not for a second. I stand to the thought that this add-on is equally interested as Half-Life was a year before this mission disc came out.

For those who remember Half-Life (and who doesn't, right? ;) they know that after that lab explosion, strange and unknown portals started to open, and you, as one of renowned scientists, had to find the way out of this hell-bunker better known as Black Mesa government secret facility which was way beneath the surface. The reason I liked this game so much is for the story -- it was the first FPS that actually gave you time for adventuring beside just shooting around (by the time, I didn't play Outlaws which is definitely one of the first shooters with great story, not to mention soundtrack). And eventually, when you finally reached the surface, the fire was open on your fella scientists, guards and you. All points that soldiers for some reason got the orders to shoot at anything that movies, no matter if it's human or not. Now that was a turnover. And now, you're one of those soldiers that you probably kill o'plenty in the original Half-Life.

Time resets, and the game starts as your team of elite soldiers are approaching to the surface of Black Mesa facility. All of a sudden, you see some alien flying 'ship' destroying neighbouring helicopter. Soon after, your own was hit by something unknown and you find yourself on solid ground. That's where you enter the top level of Black Mesa research facility. You see couple of your team members dead, and a scientist trying to revive them... or what's left of them, anyway. Not knowing the surroundings (well, of course that's unfair 'cos you know the whole building inside-out from Half-Life, hehe), your only goal is to stay alive until next orders.

The whole story, which by the way happens same time as the original Half-Life story when you played as Gordon Freeman, is now through the eyes of a soldier, a corporal Sheppard, and no matter how much things can be familiar here, it's a whole new set of everything, and you'll soon discovers that he didn't just see all the same stuff Gordon did. For your fun, only a few basic weapons will be the same as in Half-Life, the basic gun, shotgun, and machine gun, other weapons are all new, with emphasis on many alien weapons that will quite surprise you with their usage. The music is like in a prequel, only a few time appears when it's supposed to be 'suspense' and lasts like 30 secs or so, but with great sound and atmosphere in the game, it looks even more real.

Now, if you're playing a good-guy, and are familiar with the story of the original, you won't have to shoot innocent scientists and/or Black Mesa guards, as some of them will even be more usefully alive, especially for opening some doors and stuff like that. Actually, I think you can even stuck if you kill a guard that needs to open a door for you, so you'll sometimes have to protect him and clean the way to safety for him. But now you'll have much heavier fire support, as soldiers with lower rank can accompany you, and some of them have pretty much great firepower. Also, there are medics that can heal you or the other soldiers, but not with infinite medkits. And engineers can use their blowtorch to cut through some solid metal doors but as medics, they're only armored with a pistol so protecting them can sometimes mean saving your own life.

Most of aliens you encountered in the original are the same, with same way of attacks, but there are some additional that Gordon was lucky to pass them. But additional aliens stand for additional alien weapon arsenal, so now you can find alien ice-gun which will pretty much freeze every foe, or if you remember those tentacles that are hanging from the ceiling waiting to grab on something, you'll have a piece of equipment which you'll be able to use to glue on some harmless alien lifeforms and by that, whip yourself to the other side of the pit or whatever, like we only had the pleasure to encounter in Indiana Jones related games. Also, there will be some heavy automatic weapons and guns, or you can just grab some mounted turret and wipe out the incoming threat on global scale :)

Also, when you played as Gordon Freeman, you fought many enemies that weren't alien lifeforms. Now, you'll see it's not only military that gave you the headache, as those sniper terrorists and unknown soldiers will face you in this game as well. Only now you may be able to find out a bit more about that. Oh, and sweet for the last, as much as it was easy (once you know how to do it) to kill the big bad alien in the Half-Life, the one here is even more dangerous, but can be eliminated in merely few minutes once you figure how :) If there's a thing I like, that's the easy (but hard on first look) end.

The Bad
Let's see, since they managed to make a simple add-on with the quality and playability as the original Half-Life, I think that speaks for itself. Usually, add-ons are something to make money on, and don't have much of a story or new stuff. This game, however, is filled with new stuff, new aspects of playing, new strategies, new foes, new weapons, new tracks and the whole new story. I don't care if they ever make Half-Life 2 or not, but I'm pretty happy to play as many as they make add-ons if they will keep the same quality as this one, or the Blue Shift which I'm looking forward to encounter :)

The Bottom Line
If you liked Half-Life and the story seemed short from that side, try this game and see what was happening for some poor military corporal who got into even nastier positions and traps then our fella scientist. You need original Half-Life game to play this add-on, so it's assumed you already like Half-Life game (as far as I know, whoever played it liked it so far) so this extension will be like extending already short time of the original game, and with more new stuff then you imagined add-on can have. This isn't just a simple extension with kill-all-on-screen strategy, but brings you complete new point of view and complete new story. It's as if this game was the original, and the original Half-Life was an add-on, it wouldn't be much of a difference, so if you like HL, play it, if you weren't too keen on HL world in general, skip this one and try Deus Ex or something else.

The Good
When Half-Life was released in 1998, nobody couldn't predict the real revolution the game started in the FPS World. As Doom, Half-Life was one of the best FPS in all times. So, an add-on was released in 1999, followed by a stand-alone, Blueshift, where you're playing Barney Calhoun, a security guard. Being in 2008, you already know what happened to Gordon and Barney. But what about the hero of Opposing Force?

I'll refresh your mind about the three heroes of the first HL trilogy, set in the Black Mesa Era. Gordon Freeman is a scientist, working for a research center called Black Mesa and without willing it (the same can apply to the majority of his friends), triggered the opening of a portal leading to another world, called Xen. You're discovering that in reality, some scientists did know about Xen and that perhaps, it was planned to have an invasion. Gordon became the only hope for stopping it and having become a killing machine - for survival -, whether it was aliens, Marines or Black Ops, he was suited for the job. Barney Calhoun, a security guard, was working this day. Well, he did not know what or who started this bloody thing but he became an hero by fighting against the aliens and the Marines but only for a few survivors. He was also suited for some dangerous missions given by Professor Rosenberg in order to make work their only chance to escape the center. And finally, you have another hero, who fighted against aliens and Black Ops but who understood that killing guards or scientists wasn't a way for finding an exit to this hell.

This hero, it's the corporal Adrian Shepard, USMC Marine, affected to the HECU unit, specialized in anomalous threats. He's sent to Black Mesa with one goal: kill Gordon Freeman. But his plane was ambushed by aliens. He's the only survivor of his unit. He have to find a way to reunite with others Marines. And when he finds one, well, he's trapped into Black Mesa. Now, it's a matter of survival and finding a way to escape, him, his friends, the scientists and the guards of Black Mesa. What happened to him after is currently unknown. Thanks to G-Man (well if someone wants to strangle him for having taken the bad habit of putting persons in stasis, I give him or her my support).

Being a Marine, even if you have some common weapons found in Half-Life, like the shotgun or the MP5 grenade launcher, you have also the pleasure to see your weaponry increased with a Desert Eagle, a wrench (instead of the crowbar), a sniper rifle (instead of your trusty crossbow), a Barnacle (yep, it's a weapon now), an alien grenade launcher (Daddy's pet), the Displacer (allowing you to go to Xen), a chaingun, a Shocktrooper arm (instead of the Hornet Gun) and a knife. These additions are actually refreshing: Displacer have a good design, the alien grenade launcher and the Shocktrooper arm are fun to use and last but not least, if you love big chainguns making damage, well, you'll be happy.

There are also new enemies or rather a new race: the Race-X, which is difficult to say if they're siding Xen's side or if they're battling against survivors (including Marines), Black Ops and Xen in the same time. You will fear the Pits Drones or the Voltigores (these ones are pretty difficult when being adults). As for the Shocktroopers, well, you will not really fear them but you'll be jealous to see their weapons with unlimited ammo when yours is limited to ten electricity discharges. For the Giant Worm and the final boss, well, as usual, you need to figure a plan to take them out because your weapons had no effect on them. As for the Black Ops, if the female version is still present (you know, the fast women in black), the male version is making an appearance: he has heavier weapons, making him slower than his counterpart but that also means that he can inflict more damage.

That means also new allies: your fellow guys, medic, engineer, soldier but also what the first Marines in Black Mesa were ordered to kill: scientists and guards. Now, it's a matter of cooperation.

You'll perhaps recognize some places (Black Mesa Inbound, you know, your trip in the tramway at the beginning of Half-Life or Lambda Core) but you'll discover others facilities. And shoking truths.

Graphics are still good, despite having more than 10 years of age. Even if it's sometimes angular, you find pleasure to making your way in this environment.

Soundtrack is also as good as HL's. Yes, it's more a military tune but don't forget that you're in the skin of a Marine. I loved the music before fighting the final boss, it was so intense and non-military that it's still one of my favorites tracks for Half-Life.

You don't have the flashlight but you've an infrared vision but sometimes it's not practical, especially when you're in Foxtrot Uniform, in the sewers, fighting against adult Voltigores.

The gameplay is a good one, so why change it? It's Half-Life..., that means shooting, doing some specific actions for progressing and sometimes, well, you have to be careful at what you're doing if you don't want to be blown.

The Bad
Well, first thing, ladders are still dangerous to climb down. It was the case in HL and it's also the same complaint for BlueShift. So, Opposing Force, being between these two stand alones, didn't correct the problem.

Second thing is the disappearance of the crossbow for a sniper rifle (well, loving the sniping feature, I'm happy to see that it didn't disappear from Opposing Force but the crossbow is a much cooler than the sniper rifle) and more shocking, of the crowbar, the trademark for Half-Life. Well, if you see it in 2008 as a crime, in 1999, I doubt that was really considered as a bad thing. Myself, having played Opposing Force at that time, I didn't considered the change of weapons like a traitor action. Also, the crowbar is associated with Gordon (and in a less measure, with Barney) as Adrian is associated with another set of weapons...

Some players will complaint about the poverty of new enemies. Yes, we don't have to kill anymore Marines. But we got new aliens and new Black Ops. It's an add-on, not a stand-alone sequel like BlueShift (who is a good example of not adding stuff although it was needed in 2001) or Half-Life 2. Anyway, I'll complaint about the adult Voltigores who are my nightmare when I'm playing Opposing Force (well, I don't play it now but I've bought Half-Life Anthology for making it work with Steam AND XP and I can tell you that my fears from 1999 were back. It's like the spiders in Tomb Raider II - I'd play it now that I'd still do nightmares about it).

Another negative point is the Friendly AI. They have the nasty habit to go kill themselves when you're trying to tell them to follow you for being in security.

Well, I already can hear complaints about the GoldSource engine and its angular graphics. In 1999, it wasn't a problem, it was really a top engine. As I've previously stated, you can have fun with these graphics. It didn't bothered me when replaying Opposing Force, as I'm an Half-Life fan having played the game at the time of its release. So, replaying it years later hadn't making me "puke" when seeing the graphics. Anyway, I had perhaps needed to readjust to graphics (like playing Doom after years of "next-gen" graphics).

Like a lot of add-ons, Opposing Force is shorter than Half-Life (it represents 1/3 of the lifetime of HL). But it's surely long enough to keep you attentive till the end of the game. And some passages are difficult (the level Missing in Action is a fine example, as the World Collide one).

The Bottom Line
Sorry about not reviewing the multiplayer mode but well, I'm not really interested in it (apart for Team Fortress 2). That said, I'll give you my bottom line.

Half-Life Opposing Force, despite its age, is one of the best add-ons never released, like Battle Out of Hell is for Painkiller or Extraction Point for Fear. You must have played if for enjoying the Half-Life Universe and understanding the mod for HL2 The Awakening as Adrian Shepard is the hero. Valve promises us that Adrian will appear in the HL2 era but we're still waiting that G-Man pulls him out of stasis. He's the last of the trio Gordon-Adrian-Barney. HL2 will not be complete if you don't have the three heroes from Black Mesa reunited for the last fight against Combines. It would be a great symbol for the Earth, no?

The Good
What isn't there to like with ths game? The graphics are great throughout the whole game. The levels are are extremely detailed and diverified. You wander through many different environments, from the labs, to scaling cliffs, and underwater. You even make a very brief journey to the alien world. You pick up several differents weapons.You can have everything from a pipe wrench to a smart gun staright from Aliens. The multiplayer aspect of the game is 1 of the best sqad based games you'll ever find

The Bad
The story has some inconsistencies with the original.

The Bottom Line
The best expansion pack ever. It sets a standard for what a game should be.

The Good
After Half-Life blew PC gamer’s minds an expansion pack was inevitable. The idea of playing as a Marine and seeing the story from the enemies point of view is a cool idea, however this game fails to pay off of this in just about every conceivable way.

You are Adrian Shepard, you lead a squad of marines to Black Mesa to silence all witnesses. You get to see the story of the Black Mesa incident, from Adrian’s eyes. A cool idea, in concept. In execution however it is not so good.

The Graphics are on par with Half-Life’s. That means that they are not that great but get the job done.

The Sounds are good. The music is not as good as the original game.

The Gameplay tries to innovate but also fails. It feels cheap. And lame.

The Bad
The story fails largely because unlike the what the box claims your mission is not to kill Gordon Freeman, you are never even given your orders. Also scenes from the original are scarce, and when you do see them they are not as cool as they could have been. HL:OF, also introduces new weapons and enemies, the new weapons are all good, but the new aliens are crap, they are inconsistent to the plot and are too powerful. And most of the fun of Half-Life was killing marines, in this expansion you are a Marine so therefore you do not fight any. Other plot annoyances, like why would the G-man waste his time on Shepard?

The Music is not as good as Half-Life’s rocking tunes. But I suppose it could have been worse.

The gameplay attempts to innovate, with squad based actions, a medic, and demolitions guy, but in the end this just feels like a cheap Rainbow Six wannabe. Plus your squad is pretty dumb. And when the heat is on the tend to drop like proverbial flies. This game is also brutally hard. It is as if the game developers wanted to punish the player. One of the unique aspects of Half-Life was the fact that you played a scientist, which in the world of video games is the unlikely hero, this expansion places you as a solider which has been done to death in FPS.

The Bottom Line
Unlike what many claim this is no where near as good as the original. I cannot recommend it. You would be better off playing mods like They Hunger, than this crap expansion.

The Good
Just about everything

The Bad
Just about nothing.

The Bottom Line
It is a fully enthralling FPS with a great storyline. You are a marine sent in to clean up a mess some scientists left in a top secret government base. Of course, things go completely awry, and you find yourself thrown into the nightmare, in a race to get to the extraction point. This game's a lotta fun.
