The game has only bin out for a few months and there is already hackers everywhere. They spawn in guns,vehicles,teleport players all that stuff that was in arma 2. This completely breaks the multiplayer and makes it unplayable.
It be nice if you used punk buster,some other anti cheat program,or update battle eye where it can actually catch hackers.
Punkbuster is really good at updating and patching out new hacks every few weeks and if hackers get caught there $35 game will be useless since they will be banned on any punk buster server.
