Hack
Overview
One common objective of the Intruders is to hack a certain number of computer systems. By pressing the world interaction button, “V” by default, on a blue computer system, an intruder can hack the computer. Doing so a certain number of times would turn the computer (and all others in the same letter system) green, indicating it has been hacked. Two of the most common maps that use this concept are Mountainside and Cliffside.
