With PAX East kicking off tomorrow, half of this week's news has revolved around the expo organised by Penny Arcade, the games you can see there and the games you can play. Most fitting of all is the debut trailer, however, is the release of the debut trailer for Penny Arcade's On the Rain-Slick Precipice of Darkness 4, the retro RPG created by the webcomic gang and made by Cthulhu Saves the World developer Zeboyd Games.

Zeboyd's going a bit more open-world and non-linear for its second entry in the series, which it took over from Hothead Games, with alternate routes and secrets. The studio also had a bit more influence on its story, as this time it wasn't already planned before it started.

This time around, you can recruit and train monsters to fight for you too. Gotta catch 'em all!

PAOTRSPOD4 is due to launch this spring on PC and Xbox Live Indie Games, priced at $5.
