For anyone interested in participating, the bundle includes Saints Row 2, Saints Row: The Third, Risen 2: Dark Waters, and Sacred 2 Gold. Soundtracks for the two Saints Row titles and Risen 2 are also included.
Paying more than the average gets you Dead Island Game of the Year Edition and Saints Row: The Third The Full Package (all of the DLC). $25 gets you Dead Island Riptide and that game's soundtrack.
Payouts can be split four ways amongst Deep Silver, the American Red Cross, Child's Play, and the Humble Bundle operations fund. Please note that if you already own one of the games in the bundle, you will not get an extra version to gift. This is for charity, after all. You can however, gift the entire purchase.
For anyone interested, the thing runs till August 13
