This is one weird and different game
We give you a virtual unix based simulator to help you understand and perform tasks a hacker would usually need to do. It should not too complicated for a non geek player but again, I have to state clearly that this is not just a normal game but a serious competition between hackers who wants to be on the elite ranking. 10 levels available. The first training course is bruteforce crack.
