The Humble Jumbo Bundle now includes Sanctum: Collection, Orcs Must Die! Game of the Year and Cities in Motion 2.
Those interested in the additional games must pay more than the bundle's average (currently around $4) to unlock them. For those that purchased the bundle prior to their release for more than the average, games will be automatically added.
The Humble Jumbo Bundle launched last week with Natural Selection 2, Sanctum 2, Magicka, Orcs Must Die! 2: Complete Pack, Garry's Mod and Serious Sam 3: BFE. Games are available across Linux, Mac and Windows PC via Steam.
The Humble Jumbo Bundle will be on sale for six more days. The bundle has already achieved more than $2 million in sales.
