Disclaimers: cheats were used to showcase the levels of the first episode, it's not a display of skill of any kind.

Fully named "Commercial DOOM.WAD v1.0 Extra-Hard" it wasn't a proper wad but rather a pirated copy of a modified version of the game that have only replaced things (elements like items, monsters, explosive barrels or decorations like pillars and dead marines on the floor), no new levels or anything of the kind.

It was released in February of 1994, thus making this mod predate origwad by several weeks (since it was released on March of the year).

Links for the DoomWiki (the right one), DoomWorld Forum and an old video of it.
