IndieRoyale offers downloads of its Indie Royale May Hurray Bundle for Windows or Mac for $5.14. (The price will fluctuate slightly based on the number of copies purchased.) That's $10 less than the best price we could find for Dungeon Defenders alone. This bundle includes Dungeon Defenders and Brainpipe - A Plunge to Unhumanity for PC or Mac, and Containment: The Zombie Puzzler, Data Jammers: FastForward, and Weird Worlds: Return to Infinite Space for PC. Deal ends May 10 at 10 am ET.
