Delta Force 2

The Good
The gameplay is excellent and the world is very realistic. When you're crawling through grass, you can actually see every blade. Blades can block your view through the scope. Night vision. Ability to run/walk/crouch/swim. HALO insertions. Real aiming. Squads to give supporting fire.

The Bad
You can't blow out tires in vehicles using your guns. Crawling is very slow -- but that's as it should be. A turbo mode would be useful. Explosions could be better.

The Bottom Line
It's a first/third person shooter where you go into enemy territory on commando operations -- most of the time is spent crawling around and sniping.
