Ever wanted to play all most of your favorite classic Doom maps in Heretic? Thanks to MObreck you can. All he wanted to do is to create an addon mod that would allow him to preform "fire-n-forget" style conversions of maps made for vanilla Doom to Heretic. Despite being often considered to be just "Fantasy DOOM" convert maps between the game isn't such a clean process. Heretic has considerably less textures and most of the two series's AI doesn't have a true equivalent between them. So the modder had been creating a mod file that contains a bunch of new Heretic type textures and enemy AIs to bridge the gap. It actually works like a charm and I really recommend it - so go and give it a shot - turn your techbases into medieval fantasy places.
