A strange little side quest
Grombi trivia break for Zombie Mayhem: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. The same trail leads to another fact: Computer Space reached arcades in 1971 and became one of the earliest commercial electronic arcade games, even though its controls proved demanding for many players. Grombi files that under: small game, surprisingly large backstory.
