The Indie Royale "April Fool's" bundle includes Defense Grid: The Awakening, Hack, Slash, Loot, Alien Zombie Megadeath, Astro Tripper, and Explodemon. It also includes, as a bonus, exclusive access to the past.

A new surprise unlocked for the bundle yesterday is a 2005 prototype for Explodemon, used in level development of the final, polygonal version. This historical document is playable in Windows.

If you exceed the average pay-what-you-want price, you also get Sexy-Synthesizer's chiptune album Rock - Deluxe Edition. If you're considering the bundle, be sure to get this.
