Is it only multiplayer?

Yeah i got it for PC.
To tell the truth it's one of the worst first person shooter games i've played.The hit reg is complete sh!te. Aiming seems to be optional.Other wise the graphics are a bit cartoony but look good.The best thing is the completely destructable enviroment.
Even though i hate it i can't seem to stop playing it

P.S those trailers you posted make the gameplay look better than it really is.

Sounds like playing it on a console is the way to go with all the reg hacks on the PC version.

I probably like playing it on the PS3 as I can lay down on the couch and play it on the projector screen or the plasma. Its pretty relaxing except when the same guy keeps killing you.

The downside is that the PS3 controller is no where as precise or easy as the keyboard and mouse combo. A bit of practice improves things but any half decent player with a keyboard and mouse would dominate on the console. There are appararently some keyboard/mouse emulators for the PS3 that fool the console into think they are a controller. A standard USB keyboard and mouse that works on the PS3 won't work with most games.
