Doom

Doom

Players take the role of an unnamed space marine as he battles demonic forces from Hell that have been unleashed by the Union Aerospace Corporation on a future-set colonized planet Mars. The gameplay returns to a faster pace with more open-ended levels, closer to the first two games than the slower survival horror approach of Doom 3. It also features environment traversal, character upgrades, and the ability to perform executions known as "glory kills".
