Humble Weekly Co-Op bundle, some for any amount of cash you want, others for a little more, and a bunch of games for even more. Pay anything you want for Awesomenauts, Sanctum 2 and Wanderlust: Rebirth; spend $6 or more to add Rocketbirds: Hardboiled Chicken, Orcs Must Die 2 Complete Pack and Aces Wild: Manic Brawling Action. Pay $10 to get Risk of Rain.
Since this one is a co-op pack, there are two extra options to pump up the fun volume: $17 or more grants you two full bundles, and $30 or more gives you four bundles.
This week, the Humble Bundle benefits Child's Play Charity and American Red Cross.
