I have seen that the achievements in the game, are things like "get to the master level of" one of the hacking tools or "Beat the game with out getting hacked"

the second one is obvious, but how are you supposed to do it, and how do you see or get the master level in a hacking tool.

and then there are also two hidden achievements that I don´t know what even are, so if someone knows where I can find a list of this achievement please tell me.
