1. Doom 3
id's poster child of games back with more twists, turns, and fun jump scares... need I say more.
It's more fun than kicking chickens!
3. The Punisher
Interrogation techniques and enough weapons to rival the U.S. Army makes killing back-alley thugs and crimes bosses just about as fun as it gets.
4. TimeSplitters: Future Perfect
Anyone whose played a Duke Nukem game or watched an Evil Dead movie will appreciate the overall cheesiness and comic style zaniness of this unbelievably awesome addition to the TimeSplitters series.
5. Freedom Fighters
If you took "Red Dawn" set it in New York *BAM* you'd have Freedom Fighters. A great game which gives players the option of strategically targeting key Soviet bases of operations. One of the most original and creative games on the XBOX (GameCube and PS2).
