Cthulhu Saves the World developer Zeboyd Games announced that its series finale Penny Arcade's On the Rain-Slick Precipice of Darkness 4 will launch on Friday, June 7 for Windows and the Xbox Live Indie Games service.

To mark the occasion, Zeboyd and Penny Arcade are giving away free Steam codes for Rain-Slick 3. Zeboyd assures that the giveaway has no strings attached, but fans have a limited window of opportunity to hop on this deal, as the offer ends tomorrow.

Zeboyd Games resumed the Rain-Slick series after the departure of previous developer Hothead Games, producing a pair of JRPG-inspired sequels. Rain-Slick 3 was supported with a wealth of free DLC, and the upcoming sequel will likely follow suit.
