This is a 30 level scenario that truly deserves official sequel status to the original Marathon trilogy. We're so confident about that, that we're calling it Marathon 4. There are too many people that helped with this project that it's impossible to name everyone. Thank you all fans of marathon!
This scenario is truly groundbreaking in that every time you play the game, your experience will be different. No two players will ever have the same experience playing through this game. The replayability is endless!
