An demo version of a demake of the 90s Mac videogame Marathon by Bungie. This demo is an attempt to translate the original combination of adventure (and alien shooter/escape from a space ship) with the famous storytelling aspects of the game. The original Marathon featured a complex story about artificial intelligences in consoles on the space ship, and what happens when an AI goes bad. This demo is a much simpler version using text from the original game.
Avoid the aliens ("Sphot"). Find the access key on each level. Then escape by finding the exit terminal, where Leela will teleport you to the next level on the ship.

R to restart a level.
