The new Humble Bundle to benefit charity is all about the Assassins.

Ubisoft and Humble Bundle are working together offer an assortment of games: from the side-scrolling Assassin’s Creed Chronicles trilogy, to main series games like Assassin’s Creed Unity and Assassin’s Creed 2.

This Bundle supports The Pablove Foundation, which invests in education and research on childhood cancer, and CéKeDuBonheur which is another organization benefiting hospitalized children.

The base bundle, AKA the “pay what you want” tier, includes the Chronicles games and the original Assassin’s Creed.

Paying over the average will net you Assassin’s Creed Liberation HD, Assassin’s Creed 3 and the first chapter of its Tyranny of King Washington DLC, as well as Assassin’s Creed 2.

The $15 tier adds on Assassin’s Creed Unity and Assassin’s Creed Brotherhood. The games are made available to download through Ubisoft’s UPlay client for Windows PC.

As of this writing, the Humble Bundle has pulled in almost $500,000. It will be available for 13 more days.

Correction: Only the first chapter of The Tyranny of King Washington is included with Assassin’s Creed 3, rather than the entire DLC.
