Changes

'''Shareware''' is a software marketing concept where an incomplete or time-limited version of a program is released free of charge or for a nominal distribution fee, with encouragement to further distribute, in order to entice people into buying the full (registered) version. [[Doom]], and [[Heretic]], and [[Hexen]] were all both initially released as shareware, with Doom and Heretic both each containing only the first respective nine-level [[:Category:Episodes|episode]] in the unregistered version: [[Knee-Deep in the Dead|Doom: Knee-Deep in the Dead]] and [[City of the Damned|Heretic: City of the Damned]]. Later, all three games in the shareware release were brought together in a pack called the "Doom Triple Pack," where the player gets to select Doom, Heretic, or Hexen to play in the shareware release.
