Valve Software has put their own games on sale this weekend as part of their regular weekly price cuts on Steam. This time the developer has put their Orange Box collection of games for sale for a nice reduction in price.

Just in case you haven't bought the games in the set, The Orange Box contains Half-Life 2 plus the first two downloadable episodes (and when will we hear about Episode 3, Valve). It also has the multiplayer shooter Team Fortress 2 (which Valve continues to add new content to on a regular basis) and the acclaimed puzzle shooter Portal. All of those games can be yours for just $9.99 this weekend only which is a 66 percent discount from The Orange Box's regular price.
