Marathon Swamp Base

A stage I designed for the classic game "Marathon." It's a pretty dark level, hopefully not so dark that you can't tell what you're looking at.

Players must make their way into a long-abandoned research facility (the circular area near the center of the map), where an out-of-control terraforming experiment has transformed the surrounding land into an overgrown watery marsh (the jagged mazelike areas, which cover most of the map).

The building is being used as a makeshift hideout for the alien enemy, who the player must try to avoid alerting during the invasion (with their elevated position inside the base and a number of flying units, they have a tactical advantage over the waterlogged players). In an additional challenge, the entrance to the building is hidden in the swampy overgrowth, and the player's starting position is randomized, meaning each player should have a different experience when first exploring the level.

Also note that Marathon crashes if the distance viewable to the player exceeds a certain distance. One fun challenge on this map was trying to give as much space as possible to the outdoor areas, while never overloading the program - in other words, fooling the player into feeling like the outdoor areas are larger than they are.
