McMillen recently revealed that the bundle will include DRM-free copies of The Basement Collection for Windows, Mac, and Linux, along with a Steam code, a 36-page art book, a Steven sticker, and soundtracks for all featured games.

Also included are 15 never-before-seen minutes of footage from Indie Game: The Movie and other bonuses like digital sketchbooks and comics. That's a lot of stuff! The Basement Collection's retail bundle can be preordered from Merge Games for $17.99.
