A one-level (okay, two if you count the intro room) demo of an upcoming scenario. Portal of Sigma is a Big House inmate, and a promising one.

A one-level scenario, complete with new shapes and sounds - the author completed this almost a year ago, but then disappeared. It's easily up to the quality of his other Marathon work... but he had discussed adding more terminals. He never got to that... but we didn't want this to get lost, so it's been packaged up in an easy-to-use installer for your playing pleasure. The Marathon marine meets Lara Croft. This one is all puzzles - see what you can figure out!

A 10 level sequel to Operation Wormwood, the first scenario designed from the ground up to be completed cooperatively. This one has been languishing on the creator's hard drive for years - it's finally being released to the public. It's not completely polished, but it's very playable. It also contains a passel of netmaps, some original, some Bungie's. This one should keep you busy for a while!

Demo for an upcoming Marathon Infinity scenario, The Dark Star! Includes six solo maps, one introduction, and two net-maps as samples for what's coming you way.
