The final major update will be the "Overkill Edition", which will throw as much as game can without killing your framerate. Don't expect this to be available for a while.
On a side note, playing this with vanilla Doom or Doom 2 is not recommended as there are some linedefs that utilize Boom style line actions so if one must play "pure", use a limit removing port such as Boom/prBoom as the bare minimum.
Note: This is not Brutal Doom exclusive! You can play this with any mod you desire or even without mods!
These are replacement levels only and is not an IWAD, so these cannot be used as an IWAD to circumvent the need for an IWAD to use PWADs.
