New Key

Right, so my Arma Operation Arrowhead key got banned obviously for hacking.

If I go and purchase Combined Operations off steam onto the same steam account that has Arrowhead, will it give me a new key to use? Or would it be better to buy Combined Ops onto a new steam account.

Make a new account, also it wont let you buy it again on steam. If you want a key buy one here ; DayZ Selling / Trading / Buying - MPGH - MultiPlayer Game Hacking & Cheats - Hacks, Cheats, Downloads, Trainers, Games
only buy from ones with vouches and alot of posts. Dont get scammed.

It will be much easier and cheaper to buy a key here rather than buying a new arma2oa. If you do choose to buy a key from the forums be sure it has vouches and a warranty. I have been scammed before and after that I only buy keys with warranties, this way if the key becomes in-use or banned, you won't lose the money you spent on the key. Hope this helped, if so leave a thanks
