The player has performed at least one successful hack

Hack either a security bot, a security camera, a turret, a vending machine, or a safe. The first place youll be able to do this is in the Medical Pavilion. There will be a security bot that is stuck in the opening of a door at the beginning of the level. If you're facing the vending machine, it's to the right of it. These are mini-games with a time limit where you have to uncover squares and construct a pipe from one point to another while fluid is flowing through the pipe. The earlier you can get these in the game, the better since the hacks will be easier. Saving before attempting the hack is a good idea since you can reload it if you fail.
