Quake

Quake was the next major game to be released by id Software after the success of Doom. Like Doom, it was a first person shooter and was clearly influenced by Doom in its style of gameplay, design, and story. For example, Quake features a similar arsenal of weapons as well as teleporters.

Features original to Quake, like the console, later appeared in Doom source ports. Once the official Quake source code was released, some Doom source ports incorporated portions of the Quake source.
