This is where you can post your Commander Keen related stories, artwork, or other stuff that is related to Commander Keen but otherwise doesn't belong in another forum.
Szemi, you're doing a very good job but please I suggest that you work on your Keen 4 mod instead. Having 3 Galaxy mods to work on at the same time is way too hard. As long as Martinez 4 gets done, this would be pretty nice to see.
Anyway, as for modding Bio Menace, there should be a version of Keengraph that supports it, tileinfos are edited using a special version of Ck456tli, BMPatch is the BioMenace equivalent of CKPatch and the levels are edited using TED5.
