Humble Jumbo Bundle . That's quite a mouthful, and if you say it ten times fast it will summon both Beetlejuice and Candyman and open a portal to the underworld. So, y'know, it's probably best to avoid that. However, it's also the name of the Humble Bundle's latest pay-what-you-want sale, which this time discounts Sanctum 2, Magicka with two bits of DLC, and Natural Selection 2. Beat the average and you'll also get Orcs Must Die 2, Garry's Mod and Serious Sam 3: BFE throw in too. If your bank account wasn't summarily emptied during the course of the Steam sale, it might be worth a look.
That average, at the time of writing, stands at $4.10, so you won't have to fork out much of your pay packet/poker winnings/pocket money to get your hands on those six games. The charities receiving some or all or none of your money this time are Watsi and Child's Play, and there will of course be more games added to the deal over time.
The Humble Jumbo Bundle ends in a little over 13 days.
