Valve's weekend sales on Steam are usually just one or two titles but this weekend its a boatload of games that are now just 50 percent off for this weekend only. All of them are part of the id Software Super Pack that was introduced last year during QuakeCon.

That means all of the games in the Super Pack are really cheap via Steam; all the Doom, Wolfenstein, Quake, Heretic/Hexen titles and expansion packs are involved in this sale (except for Enemy Territory; Quake Wars and Quake IV, the latter of which for some reason has never been available for Steam download). If you want to get all of the games at once that's the best deal of all as the entire Super Pack, priced at an already resonable $69.99, is on sale this weekend only for just $34.99. That's 22 total games for less than the price for one regular retail new PC title.
