Official Aleph One Layout + Xbox One about 4 hours
combined playtime Adapted from the official layout for Classic Marathon (Aleph One) games on Steam but, among other minor tweaks, using mouse control instead of analog, for menu interface compatibility and better aim. (Some editing may be necessary, as these bindings are designed primarily to accommodate my own personal 12+ year old Aleph One Marathon input scheme).
