For those wishing to ride that nostalgia trip, or for some of the new comers to look back on what must be the first (if not: close) foray into the First Person Shooter game type, head on over it's only $1.24USD today, 10 May 2012.
Totally tempted to get the $49.99 for today super id software pack: Quake III Arena, Quake IV, Wolfenstein 3D, The Ultimate Doom, Final DOOM, DOOM II, QUAKE, QUAKE II, QUAKE II Mission Pack: The Reckoning, QUAKE II Mission Pack: Ground Zero, QUAKE III: Team Arena, HeXen: Beyond Heretic, HeXen: Deathkings of the Dark Citadel, Heretic: Shadow of the Serpent Riders, Spear of Destiny, Return to Castle Wolfenstein, QUAKE Mission Pack 2: Dissolution of Eternity, QUAKE Mission Pack 1: Scourge of Armagon, DOOM 3, HeXen II, DOOM 3 Resurrection of Evil, Master Levels for Doom II, Commander Keen, RAGE
The Wolf Pack with Wolf3d, Spear of Destiny and Return to Castle Wolfenstein is a bloody steal at just under $4. So much so that you're a bad person who must hate gaming if you don't get it.
And yes - Wolf3d & Spear are the full games with all episodes (Mechahitler go!)
To celebrate, Bethesda Softworks on Wednesday released a free, browser-based version of the iconic first-person shooter. Users can pick which level they wish to play in the browser version, even the secret levels."
