During E3 we managed to miss the fact that Valve's Steam service added a number of new games to its downloadable line-up. The major new additions are all of the PC games in Ubisoft's Ghost Recon series of tactical shooters. Valve has all five games in a special collection pack for $39.99 and until July 22 you can get the pack for the discounted price of $35.99.

Also added to the Steam line-up is the Monte Cristo RPG Silverfall and the indie casual puppet themed game The Wonderful End of the World from developer Dejobaan Games. Both titles are currently 10 percent off their regular price this week only
