To hack a computer, a Survivor needs to position themselves in front of a keyboard that is near a glowing blue/red computer and press [E]. The player will start a typing animation, and a progress bar will appear. While hacking, a Skill Check will appear occasionally. Failing to calibrate the Skill Check will "blow up" a computer. When this happens, an error sound will play, a fail icon will appear, everyone hacking the computer will be disrupted, and the screen will turn red.
Up to three Survivors can hack a computer at a time, which will make the progress bar go faster, and will also make Skill Checks occur less frequently.
The computer screen will go green once the hacking process is finished.
- The computers use Windows XP sounds as the operating system alerts. This may imply that the facilities are old buildings, adding to the obvious deterioration and abandonment of the maps.
- The computers on the Library map use older "CRT" displays, rather than the other maps' more modern LCD displays.
- The Homestead computers use laptops instead of desktops like the other maps.
- Players can still hack an extra computer even if the doors can be/are opened for extra EXP and credits.
