Doom: Heroes

Heroes is a 36-level megawad for Doom by Albert Dewey, created by compiling together several levels and smaller mapsets released separately. Four shovelware CD-ROMs were used to create this compilation: D!ZONE 150, Demon Gate 666, Walnut Creek's Toolkit for Doom, and the CD accompanying Tricks of the Doom Programming Gurus. In addition, Albert Dewey created four original maps for it, and tweaked or altered many of the maps included.

It has an equivalent for Doom II, called Heroes 2.
