Timeline

Marathon Dissent v1.1

The exact level count is fuzzy, due to multiple options, but Dissent is roughly 20 levels of pure Marathon fun. Realistic architecture (well, mostly - there ARE limits to the Marathon engine), a gripping story, and very well-designed gameplay add up to a scenario that'll keep you busy for quite a while.

Marathon:Evil -SDL- v1

An Aleph One/SDL conversion of Marathon:Evil. This ONLY changes to file format to work under SDL. It does not alter any levels, or change anything to utilize Aleph One's extra features. Converted by Craig Caroon.
