In Resurrection of Evil, the Martian Buddy mascot has its own point-and-shoot minigame, where the player has to shoot asteroids (with a weapon that looks like the classic BFG) to protect themselves and collect the Martianbuddies. It emerges that the Martian Buddy address is used to obscure the identity of groups warning employees of Betruger's plans via e-mails found on their PDAs, and to smuggle the combat-oriented contents through the Martian Buddy lockers. Design of certain parts of this level is very similar to the design of Mars City Underground and Mars City from the original game. Storage locker 408 - Supplies: 937.Contains: med kit (small), bullets (small), shells (small).

Both lockers also have security armor inside. Storage locker 407 - Supplies: 937.Contains: shells (small) x2. Delta Labs Level 2B's contains a BFG 9000. Administration's Martian Buddy locker contains a Chaingun and an Ammo belt with it. The storage lockers are found in Administration, and Delta Labs Level 2B. Both Martian Buddy storage lockers are the only two lockers in the game to have a code longer than 3 digits. In 2012, following the release of the BFG Edition, this code is written on the title of the message, since the Martian Buddy website has been taken down and replaced with a Store page for Bethesda Softworks. Players had to go to the Martian Buddy website to get the combination for the two Martian Buddy storage lockers. In the course of game, players will encounter two Martian Buddy storage lockers.

Martian Buddy is a fictional internet company featured in Doom 3, and players can see continuous spam of emails found on specific people's PDAs.
