Arma2 players don't know that keys for arma2Free can be used to play Arma2 MP. During installation of Arma2 you can't paste Arma2free key, because installer won't except it but luckily there is a way to use these key to play mp in Arma2.


1. Get a key for arma2 free or batter several keys. You should know how it looks in registry (the easiest way is to install arma2 free and arma2 or use arma2 key changer and just run regedit to look). Look how arma2 free key looks in registry and write it down or save on your computer.

2. Get a good Hex editor and run arma2. Note that you can use CE/UCE for this. Get the latest CE source here and use it to make undetected CE

3. Attach hex editor to a process of arma2 (to a process !!! not to exe!!!)

4.Use search option of hex editor and find your key(you should look how your key looks in registry, in windows 7 open regedit and go to hkey_local_machine\software\.....\bohemiaInterecti veStudio\Arma2 and look at key which will look like this: c8 0c 78 65 .. .. ..)

5. You’ll find 2 matches which you should replace with arma2 free key (key should look like in registry!!!). Well actually it's enough to replace the first match with arma2 free key but if you'll replace both nothing wrong will happen. After you have made changes close hex editor/CE.

6. Join any server you were battle eye banned and have your chance for revenge.(When you join first you’ll probably lost connection, don’t worry and just rejoin).

All mentioned above was tested on arma2 patch 1.11 and wasn’t tested on OA. Use at your own risk! I don't know if battleye currently detects this so use at your own risk but on non be servers it should work 100%.
As far is I know this trick will not work for OA.
Attention! After you close arma2 you’ll have to do whole procedure again. Good luck and let cheating skill be with you.

Ok here is an example for those who still didn’t get what I said:
Let’s say you have opened this hkey_local_machine\software\.....\bohemiaInterecti veStudio\Arma2 and you see c8 0c 78 65 c5 c7 78 14 0c 75 18 c5 76 14 0c. Your first step is to write these numbers in notepad. Let’s assume that you already have arma2 free key. Run arma2 key changer and put your arma2 free key in field. Now go there again hkey_local_machine\software\.....\bohemiaInterecti veStudio\Arma2 and write down numbers in notepad, let’s say numbers were c3 74 71 62 c9 c2 76 12 0c 15 14 c5 45 14 3c. Now run arma2 key changer and put your original arma2 key or just change it manually in hkey_local_machine\software\.....\bohemiaInterecti veStudio\Arma2 with c8 0c 78 65 c5 c7 78 14 0c 75 18 c5 76 14 0c (you’ll have other values sine your key in regedit will look different). All this was done to find out how your arma2 free key looks in registry.

Now run arma2, hex editor and attach hex editor to arma2 process. Search for c8 0c 78 65 c5 c7 78 14 0c 75 18 c5 76 14 0c and replace it with c3 74 71 62 c9 c2 76 12 0c 15 14 c5 45 14 3c.


Procedure of getting arma2 free key:
For this you’ll need account on facebook, liveID, steam, google or OpenID. On one account you can get only one key, so to get different key you’ll need another account.

As a result you get new GUID + ID
