So, the Day Z mod for Arma 2 is brilliant. Just fucking brilliant. You get paranoid and stop trusting anyone, people mostly shoot before they ask questions and can be more dangerous than the zombies. There are only two things that annoy me: There's a 12 hour day/night cycle that depends on the servertime. Playing at night is almost impossible, it's just pitch black. You could avoid it by changing to american servers, but they're just to fucking laggy.
The second thing that gets on my nerves is that it's almost impossible to get on any servers. Me and two friends of mine tried to get on the same servers yesterday for four hours and only made it on two. It was night and we had no chance to find each other.
