This is the second version of the Steam hack after going from BETA this is the official release:
Requirements: Only 1, WinRar.
Instructions: just run "Steam Multi Hacker V1.1.exe"
And play around with it yourself, there are a lot of other things in the program other than the account hacker such as: Entertainment (my favorite music, built in for you guys), Credit Card generator and verifier, guest pass bruteforcer and more!
Please Note: Hacking accounts can take from up to hours to days, depending on what the password is and how fast your computer is.
