Average Old-School shooter with a good story...
The guns are fairly good and the gun-play is fun, there's no ragdoll effects but your foes do have nice generic death animations. There's blood in this game but it's not over the top. The AI of your foes can be good sometimes but most of the time they will just stiffly run right to left in order to make you work to kill them. There's a nice "Bullet-Time" mode that makes certain situation a lot easier but it's not as well done as other games that uses it (Max Payne). The graphics are a mixed bag. Some levels looks great and others uses the same bland texture and objects. The character models looks good for 2003 but the animation itself is lacking. The hand animations of John Chaser (the guy you control) when he switches from weapon to weapon are really cool, that's something i noticed right away.
The sound is average and the techno music is hit or miss depending on the level you are in. The voice-acting hovers between bad to cheesy. The sound effects are decent but nothing spectacular (COD spoiled us all in the department).
The really strong point of the game is the story. It will make you wanna play those long levels just to see what happens next. The game can be challenging sometimes, but the bullet-time can swing the table to your favor if used wisely.
I'm glad I gave this game a try, in the end I came for the guns but stayed for the story.
