9/10 - Agree Disagree

I bought ARMA II: CO only to play this mod and I did not regret it. Even in this early stage of developement this is possibly the best survival game ever created! You spawn unarmed, possessing only with a few items that might help you survive. Avoid zombies, find a gun, find some food and STAY AWAY FROM OTHER PLAYERS as most of them will kill you to loot your body! And don't get too attached to your items as you will lose them anyway! Either you'll be eaten by zombies, killed by other players or you fall victim to one of the many bugs in the game (remember, it's an alpha!).
-1 point for the bugs. If the developement continues at this pace, the release version will be a 10/10. Great job, devs!
