Terminals

Terminals are wall-mounted computers scattered around the Arena. There's a grand total of 6 of them, and depending on the frequency setting, they will start sounding an alert every now and then.

When that happens, the player has to get to them before the countdown reaches zero, and turn off the alert. If they fail to turn it off in time, the terminal will start emitting heavy doses of radiation. Turning off an alert reduces the player's radiation by 75 points.

The terminal that currently sounds the alert can be recognized by the red screen that flashes bright red light. Its position will also be marked with a warning sign on the PipBoy's Local Map.

For the most part, the terminals are completely randomized. The only restriction is that the same terminal cannot sound an alert twice in a row.

The Ultimate Night's Ghost Challenge applies an altered behavior to the terminals: there, they instead go in a counterclockwise circle, and the only random element is that there is a 50% chance that a terminal will be skipped and the next one in the order will go off instead.
