MDK

The Good
In one word, this game is PERFECT. In more than one word:

• Clever and original map design. You will battle in many environments, from deserts to icy mountains, and inside high tech crawlers. This game features some of the most amazing 3D fight scenes I have seen to date, easily beating modern giants such as Unreal, Quake II, Half Life and such.
• Incredibly fast 3D engine, runs great on a Pentium 166. The engine basically utilizes flat and texture mapped polygons (as well as other nice tricks). Innovative map design and clever use of texturing helps avoid the need for lighting. MDK runs smoothly on modest hardware yet it has complex scenes and objects.
• Simple and configurable interface, which enables you to quickly learn to control Kurt. This is especially important in platform games like this, where you have to jump quickly from platform to platform, parachute while blasting away at the enemy, then landing on the floor, running for cover, switching to sniper mode and taking off people's heads from a distance. You will have to do this and more, and the this interface makes it all easy.
• High quality music and sound effects add much to the atmosphere, and change dynamically from scene to scene. I especially like the James Bond theme when Kurt surfs on the snow while shooting.
• Non stop action. Whether its classic platform actions (clever jumping and parachuting to get from place to place), shooter action (blast away or bomb every moving thing in sight) or a combination of both, you will not be bored.
• The platform game aspect. Power ups, long range jumps, running and sneaking abound. Although some might not like this, I think that this is a vast improvement over the traditional shooter style where you just go up the stairs, ride down an elevator and such. What's the point of 3D if your game is limited to running on planes?

The Bad
Nothing. Really!
Well, there is something I didn't like...
You can only save a game after each stage. Some of the stages are very long, and might take almost an hour to complete even if you know exactly where to go, what to do and you are good at the game. The option to save the game everywhere might ruin it for you, but having to option to save after a very difficult part.

The Bottom Line
If you like Commander Keen. If you like Rise of the Triad. If you like Doom. If you like fun. This is your game. I started playing the game and couldn't leave it alone for a week until I finished it. My family left me and my dog died - but I tell you, it was worth every second!

(No, not REALLY, in case you wondered)
