umm

Dude I'm a happy hacker now!

umm should i trust this.. otherwise looking good but exe...

Dude it's a joke. Youtube is only containing keystealers.

Wow ignore the people above i would never download hacks from youtube the are most likely going to be a keystealer.
If you want to be able to hack on BE (Battle eye) servers you will need a bypass, sadly theese normally cost but if you are willing to pay then i suggesting using VA (Virtual advantage)
To install hacks go to where you installed the game normally (c:-Program files-steam-SteamApps-Common-Arma 2 operation arrowhead) and drag the folders into it
How ever you can hack without a bypass but on servers without BE (Battle eye)
Hope this helps

yea well i think im gonna stick whit the legit gameplay then if it costs :C

There are the rare free bypass but they are very very risky

yeah i dont have too much money so nope

as i said in my other post im gonna stick to legit gameplay then

Very true if you do lose your key then you can get another for around $2-3
