Some time back, I tried a face tracking thing (a bit like TrackIR) using a webcam which worked surprisingly well with ArmA 2 and DayZ. There's little difference between the difficulty levels, but the maximum issue will disable eyesight dots, crosshairs, your position on the map and third person perspective.
Your sport is installed properly and it sounds like your shortcut is fine (given that it reveals the beta as a extension), which means you need to be able to see DayZ servers. DayZ utilizes the sport map (Chernarus) in ArmA 2 along with the game engine from Operation Arrowhead, which means you need both.
last day on earth survival hack I would advise that you attempt DayZ Commander as that puts the documents in the conventional location and it automates the process of connecting a host (you choose a server via DayZ Commander and it starts the match and joins the server for you). Their account says that Swallow was at the very first group of ICF who came up the west from the NB stairs (and got humiliated then put in the reduced west tier by OB for the remainder of the match) in a 'small mob'(150 powerful!) &proceeded to batter us!
So you might have a DayZ forums consideration, in which case you ought to know that they have been hacked and you should do that whole password-changing dance. My entire private experience of DayZ can be summed up having conducted round in the dark, got attacked by some zombies, panicked and hurried off, and managed to lose them before bleeding to death in a churchyard".
