Bargain indie bundler IndieRoyale has unveiled its latest package, the May Hurray bundle.

The pack contains Dungeon Defenders, Containment: The Zombie Puzzler, Data Jammers: Fast Forward, Brainpipe - A Plunge to Unhumanity and Weird Worlds: Return to Infinite Space.

All of the games apart from Weird Worlds provide Steam keys. Dungeon Defenders and Brainpipe will run on Mac.

Unlike the Humble Indie Bundle, Indie Royale does not allow you to pay what you want - the price increases as more people purchase the deal, though the price can be decreased by people paying above the bare minimum.

And those who elect to pay over $7 (or their currency equivalent) will also receive chiptune album Future, Toward the Edge of Forever by Starscream. I haven't listened to it.

At time of writing the May Hurray bundle has been sold 12,016 times and is currently available at a minimum price of £3.30.

The bundle will be available until Thursday May 10. That's six more days for those interested.
