Doom 3

Doom 3 is a sci-fi horror FPS developed by id Software and published by Activision in 2004. It's a good game, but it's a very particular entry in the franchise, almost like a spin off.

You are not "THE" Doom Guy this time, but just a regular UAC employee. You are not the danger. You are in danger.

Regarding plot, it's like a reboot. Everything started with a terraforming project on Mars. During the initial construction of Mars City, UAC engineers discovered underground ruins and structures of what used to be an ancient Martian civilization that existed millennia prior. Then they discovered stones and tablets, related to a teleportation technology. But... the dimension on the other side was none other than hell.
