While MP is under-developed, the other extra mode is really well designed. Called Bloodshot Fight Club, this is a range of fighting mini-games – you can murder endless waves of hobos or try one of the other modes where there are actual objectives to complete. They're all well thought out and it's a fine addition to the game.
The violence is uncompromising, the graphics are frighteningly realistic and the language would embarrass a trucker. Still, the game is fun and despite its silly story it's addictive. You should buy this game – get it before the OFLC realises the mistake it has made.
