Off to a good start!
The weaponary is good, with the Bullseye being one of my favorite weapons. Nothing like tagging a nasty and then unleashing hell. While the game is good, and the sound even better, this game doesn't show off the PS3's capabilities. It's as good as Gears of War in graphics and sound and gameplay is decent. Cons
Very limited SIXAXIS motion controls. You shake the stick to shake off Chimera (shame on you for not firing fast enough).
Could have had better co-opt gameplay (ability to jump in and out of this mode without it effecting levels)
More story-line though I imagine #2 will fill in the gaps.
