Quake

Quake was the next major game to be released by id Software after the success of Doom. The first release was on June 22, 1996. 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. Also, Doom 3's engine is a spiritual successor of the Quake engine (and was used in Quake 4). Another noticeable connection to Doom is that in the later versions one of the playable character's helmet is similar to the helmet on the box art of the first Quake.
