The Humble Jumbo Bundle is now packed with three extra games, Sanctum: Collection, Orcs Must Die! GOTY and Cities in Motion 2. These join Orcs Must Die! 2: Complete Pack, Garry's Mod and Serious Sam 3: BFE behind the "pay more than the average" curtain. Games behind the "pay whatever you want" curtain are Natural Selection 2, Sanctum 2 and Magicka plus two of its DLC packs.

All games come with Steam keys. The Humble Jumbo Bundle has already raised more than $2 million benefiting a mix of the developers, Humble itself and two charities, Child's Play and Watsi. The sale is on through December 17.
