When the player meets Larry Kaczynski in Doom 3, he is trapped in a chamber as a result of a power failure, and asks the player to unlock the doors. After the doors are unlocked, the player takes a lift down to Kaczynski's location. Kaczynski thanks the player for freeing him, and states that he does not know what is going on or why none of the systems are responding. He furthers states that he'll attempt to establish an uplink into the main system from his secure terminal. If the player persists in speaking to him, he will state that he's not going to leave until he's figured out what is going on.
