yes. that's a leading statement but let me explain.
after several years of development, changes and endless hours simulated combat, major crisis is now reborn as (perhaps) it should have been. as such I've temporarily re-opened development while the bug reports (that I hope are few) come in and are handled...
what I'm talking about here is the Major Crisis - Ultimate edition.
within this version you will find the collective works of the major crisis mod, including EP, and also, as an added bonus, its finally adapted for Gzdoom support.
Yes that's right after all this time its finally possible to play major crisis in gzdoom without missing features and effects. I hope! still not quite finished testing it so this may require some minor changes here and there.
so far its had a few hours of testing and changes to majorcrisis_z.pk3 (now known as majorcrisis_Gz.pk3) and btsx_fix.pk3 have allowed the mod to function in gzdoom. you can now use mc_ep.pk3, mc_monstas.pk3 and the sky and fix packs without error. you'll still get a few error messages upon start but they're not critical to gameplay or function, just gzdoom telling you that the code is badly fudged!
but, worry ye not zdoom users, it will still function in zdoom 2.8.1!
here it is:

please understand that this version is intended as a replacement to the other major crisis files available. not to be run in tandem with them but instead of them... you'll figure it out I'm sure

please report any bugs and I'll endeavor to fix 'em as soon as I can!
