It got crap reviews (yes, CRAP. When almost every game released gets a 7-10 score, a 6 is crap).
They fired gerstmann from gamespot because he gave it a 6 and then eidos threatened to withdraw their advertising money. Then they pulled the video review and edited his textual review.
Eidos flat out fabricated the reviews on the games official website.
The multiplayer certainly is a good idea, but apparently gets tired pretty quick.
The game is pretty hard to control apparently with an almost useless cover system and mediocre level design.
And bad language is only an appeal in a game if you're 14. In Kane and Lynch it's overused and just becomes offensive.
They lost my pre-order with the gamespot scandal.
