Evaluation
Penny Arcade's On the Rain-Slick Precipice of Darkness 4 is the concluding entry in a four-part RPG series. The store description explicitly frames this as the conclusion of the saga, indicating it was designed and shipped as a complete, standalone narrative product. Zeboyd Games has never announced any post-launch DLC, expansions, or additional content for this title. The only developer news post associated with this game on Steam (from May 26, 2017) is simply Zeboyd Games announcing their next game, Cosmic Star Heroine — a sign that the studio had fully moved on from this title years prior. There is no history of post-launch content updates, no unreleased DLC, and no developer statements suggesting future additions. This game launched as a finished product and remains complete.
Evidence
Store description explicitly states the game 'concludes the saga' of the main characters, framing it as the final entry in the series with no suggestion of future content.
Zeboyd Games' only news post for this game announces their next title, Cosmic Star Heroine, indicating the studio had moved on from the Penny Arcade series entirely.

About this game
Penny Arcade’s “On the Rain-Slick Precipice of Darkness 4” concludes the saga of Tycho Brahe, Scion of The Long Project, and his almost certainly human partner Jonathan Gabriel. The world has been destroyed, but existence extends beyond this mortal plane in the gruesome Underhell! The new game expands considerably on its predecessor in size, scope and gameplay. Create the ultimate fighting force by recruiting bizarre, occasionally disgusting monsters and teaming them up with the best trainer for the job!
