Penny Arcade released its retro-style RPG On the Rain-Slick Precipice of Darkness 3 not too long ago, and the web comic company is already planning a follow up episode.

A new post today on Penny Arcade's website says the first of two download content for the game, "The Lair of the Seamstress," is being finalized. The content is free and will likely be out before the Penny Arcade Expo next month in Seattle, Wash. It also says developer Zeboyd is behind the eventual fourth episode.

"Zeboyd is coming up tomorrow to work on Rain-Slick 4 and the last DLC (also free) for the current one that details the fate of the player character from the first two games," the post reads.
