Having a total blast playing through, and how it cleverly quotes the original campaign is always a treat.
In answer to Dylan_Dog's first point in his review - being restricted to the m2 shapes, it should be subject to m2 shapes mods including the "Transparent Liquids" (With modification to the plugin.xml file to allow the scenario) or XBLA texture mods that already have transparent liquids enabled, e.g. Community Freeverse Plugin or TheDoc45's M2 Super Plugin. Works for me so far.
In celebration of the 30th anniversary of Marathon 2's release, this is a 28-level scenario using the same story of the original game and similar constraints, blending together classic and modern level design styles to make an exciting revisit to Lh'owon.
