I enjoyed this game quite a bit. Although it was fairly short (the single-player campaign), you can never have too many good, smooth FPSs. The multiplayer (especially with bots) adds some replay value, although it's hard to understand how they could not include system link play.
Gameplay is fairly reminicent of other FPS. The really cool thing is that you can make a TOTALLY customize your controller configuration, by remaping every single button available. This is what everygame needs to include. The mouse-look is smooth and responsive, though not as responsive as the best FPS I've played on Xbox so far: Return to Castle Wolfenstein. Since you can remap the controls there's really no reason to complain or gripe about the game play since you can setup the game to your hearts content.
The Geo-Mod feature is phenomenal once again and is smoothly interlaced in the single player with bonus objectives hidden in some areas and behind breakable walls as well as some primary objectives. The weapons and graphics are also sweet at lower resolutions. There was no slowdown for me as compared to many recent games I?ve reviewed.
Again, nothing truly note worthy. Good explosions, decent voice acting. The only thing I really liked were the incessant "Big-Brother" type rantings by Sopot (over PA systems everywhere).
