 * In System Shock 2, TetraCorp is responsible for minority of technology and systems aboard the Von Braun and UNN Rickenbacker, such as keypads and other standardized controls for doors, hatches and elevators, as well as refrigerators and nacelle control computers.
 * TetraCorp probably also designed the TC-11 "Brick" Grenade Launcher and the TC-5 Fusion Cannon, even if the latter is produced by TriOptimum.
