In this entire 50-level scenario from NEFX, complete with an entire original soundtrack, you navigate strange, puzzling, and sometimes perilous terrain to clean up hard dust balls with your trusty Yucatan Suckaman™ vacuum cleaner. Just watch where you step, and be sure to empty the bag often so the vacuum cleaner doesn't explode!

Marathon: Sucks is now officially a full-fledged scenario. All 50 levels have been merged and flowed together into a pack complete with original music tracks and terminal messages. Get ready for some hardcore cleaning. You can download the whole package at the provided link as well as any of the individual maps.
Great little humorous mod for marathon, definitely a rarity! First terminal had me laughing out loud. Only the truest gamer imaginable could beat it on stream or something. Desert Bus/Marathon: Sucks for charity?
