Futa Prision v1.3.7B Released
Futa Prision has moved to version 1.3.7 B, the latest maintenance update from developer Ninja Head for the long-running corruption RPG. The “B” build follows close on the heels of 1.3.7, signaling a fast turnaround aimed at tightening up the release rather than introducing a fresh story arc.
Futa Prision casts a male protagonist inside a prison overrun by futanari inmates, with an RPG-driven corruption loop: characters can be broken down, converted, and folded into the player’s growing harem over the course of the sandbox. The game is built with internal-view mechanics and animated 3DCG scenes, and it’s accumulated a sprawling tag list over its development — from lactation and vore to multiple endings — reflecting how much content has stacked up since its earlier releases.
Point releases like 1.3.7 B typically bundle bug fixes, save-compatibility patches, and small content corrections uncovered after the previous build shipped, keeping the sandbox stable for players working through its branching corruption paths and multiple endings. For a game this far into its version history, incremental polish passes like this one matter as much as new content drops — they’re what keeps a multi-year project playable as its systems pile up.
Futa Prision v1.3.7 B is available now for Windows, with English and Spanish language support.
