I'll admit that I only bought ArmA2:OA (+ArmA2:Free) for DayZ xD

Anyway, all the hacker stuff shows how bad the engine is really done, and that Battleye is crap.
ArmA2 servers do not follow the guideline for good server infrastructure! Servers should be the authority saying what is true and what is wrong. In ArmA2 part of the game is calculated clientside...... all the player movement, aggressive zombies and cars are calculated clientside which makes it very easy to just say Player:SetPos(x,y,z) in their scripting language and there you go, I can think that dieing and getting hurt also works all clientside from all the delay after being shot. What also is a big mystery for me, why does the server lag so much and use so much hardware...
I myself didn't play ArmA3 yet so can't say if they changed it or not... but its a really bad server design with ArmA2... oh... and about Battleye, its a piece of crap which is buggy and even bans innocent players... I played with a friend which had to rebuy his game the sixth time because apparently his keys got banned, especially after a stupid "script kiddie" (not hacker, they dont exist in arma2/dayz) done crap on the server.
Script kiddie shit can be fun sometimes (see attachment) but just for a moment, but when its about like teleporting stuff around the world, spawning stuff, killing everyone with just a button and other crap then I would really just want to beat his face up with a bat irl....

Other than that, DayZ is fun :3 and I had to kill 4 people that tried to get under mine/plums skin yesterday...
Killed 2 people that tried to ram the bus I was in, shot the passenger first, then the driver that exited.. sadly the V3S truck also blew up for some reason...
Then there was a player shooting with a makarov at one of us...
and the 4th player was a sniper (suspected for scripting! spawning stuff like night vision, DMR and whatnot). He killed 2 of us and then thought nobody was there anymore, while I was hiding in the Scrap APC, he ran to the corpses, i got out and shot him a few times.
