Steam Greenlight is a dog-eat-dog popularity content, so every little helps. Hence it's time for the twelfth Indie Royale Debut bundle, which includes eight games that want your attention and votes.
You'll need to beat the minimum price (which changes periodically, but won't reach over £3.00 by my reckoning) to receive Gearcrack Arena, Luna’s Wandering Stars, Pester, Rot Gut, Selknam Defense, Storm over the Pacific, You Are Not A Banana: Chapter 1 & Yrminsul.
I can only personally vouch for Pester, which is a simple yet satisfying bullet hell/danmaku shooter that first released as an Xbox Live Indie Game. Naturally you won't get Steam codes (DRM free downloads and/or Desura only, I'm afraid) - until or unless the games eventually get Greenlit.
