Indie Royale has announced the Replay Bundle Vol. 1 today, offering a variety of games such games as Nuclear Dawn, Gemini Rue, Defense Grid: The Awakening, Soulcaster and Soulcaster 2 for a very low price. The bundle also includes the soundtracks for Soulcaster 1 and 2, a remixed soundtrack for Soulcaster 2, and six DLC goodies for Defense Grid (the Borderlands DLC, Resurgence map packs 1 - 4, and You Monster DLC). The extra stuff is only available on Steam.
While the Indie Royale bundle is a "pay-what-you-want" deal, paying more than $8 will get you some extra stuff like the 8 Bit Weapon Collection, a 56-track digital album covering a decade of music from 8 Bit Weapon and ComputeHer. You can find out more about that part of the bundle here.
