Slightly Under rated
Cons -
Buggy AI - they straif left and right most of the time, or just stand still.
Usless weapon choices - most of the time you will go in with same weapon OR with an upgraded version of the same weapon.
Strait forward game play - No real open game play.
Odd or missused sounds - Some sound FX are just too out of place.
Video problems - Odd colors or video fragments at times , looked like clipping problems.
Respawning enemies - Ive said it before and I'll say it again. I HATE respawning enemies
Pros -
Game length - More lengthy than your average PC FPS.
Game play - Slightly more engaging than your average PC FPS ( i can name a few that really let me down )
Non consistant AI - Yes they do nearly the same thing over and over , but never in the same way. I know it sounds odd , but I hadly ever faught the same battle the same way twice.
Fun weapons - Yes there are some useless waepons, but some are quite fun to shoot with , and head shots are still an addiction.
Video goodies - Weapon muzzle flare , vehicle and weapon design , along with that shiney metal effect on them are all top notch.
Engine - Interactive physics engine.
All in all this is a better than average FPS that I dont think got as much praise as it should have.
