Media Munger is an effect for use with Chisel 2.0 or later that can remap the media in any Marathon 2 or Infinity map to any of the types available. It works on unmerged maps, but its alterations are removed by the merging process, so simply reapply to the merged map.

It is perfectly possible to crash Marathon hard using this effect. Each media type references a specific medium texture (from the various wall collections) - if you can see the surface of a medium, then you must have that wall texture collection loaded. Similarly, the splash effects played when you fire into a medium/enter it are in the scenery collections - if you fire into a medium you must have these loaded as well.
