The Rain-Slick Precipice of Darkness series is finally coming to an end, and we've got a glimpse of the action through a finale teaser from Penny Arcade and Zeboyd.

The finale is the fourth chapter in the series and has our heroes, Tycho Brahe and Jonathan Gabriel, traveling through a destroyed world and continuing in an Underhell. Rain-Slick Precipice of Darkness 4 will be a playable demo at PAX East this weekend. 

"On the Rain-Slick Precipice of Darkness 4 is shaping up to be our biggest, most epic RPG ever!" says Robert Boyd. "We look forward to everyone's reaction when they get a chance to play it."

The game is slated for a Spring 2013 release on Xbox for 400 Microsoft Points and PC for $4.99. For more information, check out the official website and watch the teaser below.
