Here’s the full list of multiplayer maps available at DOOM’s launch:

• Excavation. A modest-sized UAC mining outpost. Watch out for the rock grinder!

• Infernal. A mid-sized Hell map with both interior and exterior elements. Lots of platforms and chasms, along with teleporters.

• Chasm. This massive map takes you deep below the polar ice caps of Mars. A great place to play Freeze Tag.

• Disposal. This smaller map is the main waste processing facility for the UAC research and residential complexes. Unsurprisingly, it’s full of radioactive slime.

• Helix. This is where they experiment on demons and develop advanced weaponry. Which, naturally, makes it perfect for a quick round of Clan Arena.

• Perdition. Disjointed and sadistic, this ancient arena is populated by the agonized moans of unfortunate souls who have suffered within its realm.

• Sacrilegious. Set within a fracture of Hell, this map offers clear lines of sight. Move fast… or die faster.

• Heatwave. An industrial UAC facility with glistening halls that will soon be slicked with human (and demon) blood.

• Beneath. Before being beamed to Earth, the energies of Hell are harnessed in this symmetrical and cavernous location.
