: : Are there any future plans for adding co-op support for Marathon 1?
: We have ideas, but nothing concrete yet. As explained last year ,
: exploration missions worked differently in Marathon 1, in a way that's not
: co-op friendly. M1A1 simply modified the maps to fit Marathon 2's
: exploration type, but our goal is to run original Marathon maps (including
: third-party maps), so tweaking them isn't an option.
: For Marathon 1 co-op, the best solution is to use the Marathon data from
: Aleph One 1.0 , as that's the most faithful version of M1A1.
Did they ever get rid of the M1A1 changes — i.e. the weird Pathways thing at the beginning, the short-circuited Deprivation Chamber, the Colony Ship For Sale puzzle, the extra credits terminal (IIRC), etc., or is that stuff still in there? My memory of M1A1 is it not really feeling like the same game, but maybe that changed at some point.
As for the problem being discussed, is it too much trouble to change the engine to make it register when you've stepped on a polygon instead of just looked at it, but only when the game is in coop mode? Or do the map files do things like put goal polygons in places that you can see but can't get to?
