Summary
Minor problems, but an overall good package for PS2 shooter fans
The Good
All 1st person shooters try to out do the previous standard. Take Half-Life or Counterstrike. When they were released, very few games had the same amount of action and playability to them. But have a look at today, and see how many games have tried to emulate both titles. The only game, to my mind, that has tried something different, not just in looks but in gameplay, is Red Faction. And the reason why is simple: Geo-Mod.
The inclusion of this graphical beast has allowed not just a new way to design the graphics engine and to include more detailed terrain, but to allow a more interactive environment, which in turn changes the style of the gameplay into a more tactical style then just run shoot (as in Quake 3). For example, instead of taking out the many guards waiting in your path on a bridge, just take out the bridge. Of course, some limitations had to be made, otherwise you could blow up Mars itself, but just having that ability is a major step in the development of first person shooters.
The other major task that I believe has been captured well is the mix of serious combat and laugh out load moments. There are plenty of moments with the guards that will get you laughing (at times, the guards will shout out "I don't want to die" just as shoot them). This adds a bit of fun to the serious nature of the storyline.
The Bad
Put simply, multiplayer support. These days, you can't have a shooter without a 4 player mode. Quake 3 and Timesplitters accomplished this well on the PS2, but the lack of 4 player support here hurts the the overall package. I can, however, understand why. It would have been very difficult to have 4 on together, as well as having a smooth game, Geo-Mod and all.
Some may also have problems with the control system. I have this down to a fine art, but others will hate the lack of Keyboard and Mouse support (especially when the PS2 sports two USB ports).
The Bottom Line
For those who have a PC and PS2, I would suggest the PC version mainly because of better multiplayer support.
But besides what I have mentioned, Red Faction is still a worth while purchase for the PS2. Two player multiplayer games are still plenty of fun, and the single player game will take a lot out of you. The Geo-Mod technology is a reason in itself to take a chance on this.
