T. Brooks

"Welcome to the dungeon, Marine, most unexciting place on Mars."

- T. Brooks

T. Brooks was a security guard character in Doom 3 located in Mars City Underground. He welcomes the Marine upon his entry into the Underground, calling it the most unexciting place on Mars.

Brooks permits the player access to a security locker containing a pistol, armor and a flashlight. When the player gets into his office after the demonic invasion, Brooks has been turned into a shotgun-wielding Z-Sec, and the player has to kill him.

He seems to be very well known in Mars City Underground as he is found in every PDA of every UAC employees in that area.

Trivia

 * If you discharge your pistol when you first receive it, Brooks will flinch and yell at you to be careful.
