Dead of Night is a 2D platformer set in the world of Ancient Greek mythology. The game was developed for the Enix International Entertainment Contest in the Fall of 1996. The released version of Dead of Night – which is only a demo – only contains the first quest given by Zeus to Heropheles: to slay the Hydra and retrieve the map of the Underworld. The continuation of the story is hinted at but was apparently never done, otherwise the game is feature-complete.
