[STEAM]Quake

From Wikipedia

Quake is a 1996 first-person shooter video game developed by id Software and published by GT Interactive. The first game in the Quake series, it was originally released for MS-DOS and Windows, followed by Mac OS, Linux, and Saturn in 1997 and Nintendo 64 in 1998. The game's plot is centered around teleportation experiments, dubbed slipgates, which have resulted in an unforeseen invasion of Earth by a hostile force codenamed Quake, which commands a vast army of monsters. The player takes the role of a soldier, whose mission is to travel through these slipgates in order to find and destroy the source of the invasion. The game is split between futuristic military bases and medieval, gothic environments, featuring both science fiction and fantasy weaponry and enemies as the player battles possessed soldiers and demonic beasts such as ogres or armor-clad knights. Quake heavily takes inspiration from gothic fiction and in particular the works of H. P. Lovecraft. The game went through many revisions during development, and had originally been inspired by a Dungeons & Dragons campaign held among id Software staff.
