AI

The Artificial Intelligence (AI), is an artificial intelligence, and serves as a major antagonist of Subject 4. The protagonist is frightened of her.

Personality

 * As a robotic AI and user interface, she is shown to be pretty much devoid of personality and human emotion. However, the AI is shown to be persistent and relentless, being very dogmatic about its programming. The AI does not distinguish between employee and intruder, attacking on sight.

Gameplay

 * The AI has a voice cameo in part 3, mistaking "Parker" and Security Guard 2 for intruders and subsequently attacking them.
 * In part 6, she is the main/only antagonist, being in charge of security. On the way to the power room, the protagonist must dodge her lasers and guess the correct security code.
 * In the power room, the AI notices an intruder (despite the protagonist presumably getting security clearance (if they figure out the code).
 * The AI tries to release the Toxadoma Mucii but fails due to the pipes being clogged (The reason for this is unknown, but the main candidates are Subject 2 and Subject 1).
 * Instead, the AI sends down a battle droid, which you must duck and cover from to avoid the lasers as you run back to the temperature room, also avoiding lasers.
 * After being pinned down, use the ax to remove the eye, temporarily stunning the AI.
 * In the temperature room, go to the right side to avoid the blast of the self-destruction.
 * In part 7, she has two cameos, one in flashback, and the other being when revealing the "toxic brew" within the protagonist.

Trivia

 * The AI is one of the only characters the protagonist is shown to fear, though Subject 1 is possibly another.
 * The AI is also one of the only characters to be voiced with a speech synthesizer, with the loudspeaker man being the other.
 * The AI is partially inspired by the Terminator.
