This was a great first person game - I couldn't put it down until I finished it. However, the multi-player disappointed
However, don't plan on bothering with the multiplayer - this area of the game was down right pathetic. I suddenly had visions of playing original DOOM, and unfortunately, they were starting to re-write my original memories of how good DOOM was at the time. The multiplayer levels were horrible, small, boring and only a handful of online people can play - BORING!!!
Borrow this or rent it - you can finish the single player in a couple of days at most, or even one day if you have to. Then, get rid of it - no use keeping a bad multiplayer game around.
