its alot of fun, I tried playig it online, but unfortuatnly people are completely retarded!, i joined a 3 way game and the other people just kept running around on the bottom of the screen shooting guys as they showed up without progressing at all..

played up to the point with the jeep on level 1 and they just didn't understand the concept of scrolling forward.

still a fun game but i'll stick to the 1player version ;-)
