Heretic Shareware (Raven Software, 1995)
1Three Serpent Riders conquered the world by enslaving the minds of men. Two of the Riders leave, but D'Sparil remains behind and the seven kings of Earth succumb to his mind control. You play a member of the Siddhe Elves, who are scattered across the world after destroying the seven armies. In this first person shooter based on a modified Doom engine, you use a staff to fight evil creatures in your quest to kill D'Sparil. One notable improvement to the Doom engine is the ability to look up and down. Originally Heretic was only available through shareware registration, until GT Interactive started distributing a retail edition called Heretic: Shadow of the Serpent Riders which added two more episodes. There are 5 episodes in this game, with only the first episode playable in the shareware version.
