Veteran game developer John Romero took to Twitter today to spread the word that he's made a new Doom level, something he says he hasn't done in over twenty years.

Romero's return to the game that jumpstarted his career in game development is a fun little Friday surprise for developers, especially Doom enthusiasts, some of whom are thanked in the readme file accompanying the level.

The new level, E1M8B, is described simply as "My Boss level replacement for e1m8...22 years later." E1M8 is, incidentally, the final level of Doom's first episode, Knee-Deep in the Dead.

Among the contributors mentioned in the level's readme file are JP LeBreton, who sat down with Romero to do a "Dev's Play" video of Doom that was published early last year, and the DoomWorld modding community, which is still going strong over two decades on.
