    Doom 3

    Doom 3 was an excellent first-person shooter survival horror which made for a challenging single player experience. This atmospheric game was set in a research facility on Mars and featured an exciting back story. Battling your way through the dark corridors you faced a variety of nasty creatures looking to end your life and in order to progress you had to glean bits of information from people you’d meet along the way and documents you could find lying around. Many of the doors required codes to activate them and finding ammunition was a constant challenge.
