One Man Left was working on more DLC for Tilt to Live 2 [$2.99] after the Brimstone Pinball expansion. However, it apparently the scope of the new DLC grew and expanded into something so big that they had to put it into its own game: Tilt to Live: Gauntlet's Revenge.
This is a reimagining of the Gauntlet mode from the original Tilt to Live [$2.99 / Free / Free (HD)], where the goal is to avoid deadly traps, rather than destroying dots. One Man Left hopes to dramatically improve on that original mode by adding in lots more variety in levels and enemies, bonus rooms and more. The mode is still in the works, but it sounds promising. Gauntlet's Revenge will be available as a separate app from Tilt to Live 2.
