I tried the demo for this on the PSN and came away pleasantly surprised. I just made this topic for anyone who is into Left for Dead style 4-player co-op who may have otherwise not known about it. I only played through the demo stage twice but overall I found it fairly well done. It's basically the same idea as LFD, just switch from zombies to cops while heading for your objective. The game mechanics are fairly similar. There are skill trees and weapon unlocks as well. Anyway, i'm most likely getting this tomorrow. Unless I missed something, this should get favorable reviews...I hope.
