Humble Bundle offers downloads of the Humble Jumbo Bundle for Windows
for whatever you want to pay
. If you opt to pay the bare minimum of $1, you'll get Natural Selection 2, Sanctum 2, and Magicka with DLC. That's at least $44 under the lowest price we could find for downloads of these games elsewhere.
If you opt to pay more than the average, currently
, you'll also get the Orcs Must Die! 2: Complete Pack, Garry’s Mod and Serious Sam 3: BFE!, a low by at least $76. Your contribution can be donated to charity (Watsi or the American Red Cross), the developers, or both. Deal ends December 17 at 2 pm ET.
Of note, these games require a Steam account for activation.
