Not the best i've ever encounted... but fun nonetheless.
It's got great co - op and awesome single player. Always fun to play... but mostly played when there is nothing else to play.
It's one to play at parties (nerd parties) because it keeps others entertained so you can stop them touching your good games.
I found the aiming a little unusual to begin with, but I got used to it later on.
Co - op would have to be my favourite thing about this game. Nothing better than cuffing stoners with your buddy.
Overall... fun game!
