In advance of a public appearance at PAX East this weekend, Cthulhu Saves the World developer Zeboyd Games has released a teaser trailer for its upcoming retro-styled RPG Penny Arcade's On the Rain-Slick Precipice of Darkness 4.

Much has changed for the newest chapter in the series. The world, as players knew it, has been destroyed, and the game's cast must now battle through the Underhell in search of their teammates. Zeboyd notes that Rain-Slick 4 "expands considerably on its predecessor in size, scope and gameplay," and offers a new monster-recruiting mechanic during battle sequences.

On the Rain-Slick Precipice of Darkness 4 is set for release this year for Windows and for the Xbox 360 via the Xbox Live Indie Games service.
