Jensen when he was accessing a computer terminal investigating his dismissal. It is around this time that the game begins.Įarly on in the game, the Marine meets Dr. During the same time, demons started to invade the installation, appearing out of nowhere. Jensen suspected that Guerard was involved in his dismissal. Jensen failed the security audit and was dismissed for this security breach. Three weeks prior to the start of the game, Guerard asked Graff to perform a security audit on Jensen. Guerard was not on good terms with Jensen. The Junction is the staging area or main town for the game. The sectors are Entrance, Junction, Sector 1 through Sector 7, and Reactor. The game is divided into section based on Sectors in the base. The player is addressed to by NPCs in the game as Marine. The story occurs on a Martian Union Aerospace Corporation installation similar to DOOM 3.

A dog collar-like mind-control device allows the hellhounds to be captured as pets, which can then act as both a melee weapon and a shield. The dogs from Wolfenstein 3D appear as a new enemy, known as Hellhounds. New weapons include the fire axe and fire extinguisher which are useful in combat against certain enemies. A difference from the original is that each monster is one of three levels of difficulty, and is colored to indicate this.

Notably absent are the Chainsaw, Arachnotrons and Spider Mastermind. Many features of the original are retained, including the status bar face, sound effects and the majority of the weapons and monsters. It is very important to speak to the scientists and access computer terminals to attain vital information in order to progress through the game, similar to Doom 3. The player turns at 90 degree angles and moves space by space.

Combat and movement are turn-based, allowing the player time to select their responses in combat. However, the game is fundamentally different in that it is a turn-based role-playing game, rather than a shooter, with greater emphasis on the plot. It is also visually similar to the original Doom. The game retains many of the elements of Classic DOOM, and is shown in the first person like the original.
