Finish Doom: The Dark Ages

Rip and tear on Mars to Mick Gordon's metal; id reboots Doom as speed.

The Doom Slayer with a meat hook and a resource loop; faster than 2016.

A flashlight or a gun, never both; id turn Mars into survival horror.

The BFG, the imps and the shareware episode that ran on every office PC in 1993.

The super shotgun and the Icon of Sin; thirty more levels of 1994.

True 3D, brown corridors, a Nine Inch Nails soundtrack and the birth of deathmatch.

Climb the tier ladder past the bots to Xaero, then stay for the rocket jumps and rail shots.

Quake III rebuilt to run in a browser, then moved to Steam; the arena game kept alive for a decade.
