Forbidden Dungeon is a lewd dungeon crawler with roguelike play, made with Ren'Py by Dark Forge Studios. You play as the protagonist in a dark fantasy dungeon world where corruption is a temptation and heroes face twisted fates between duty and desire. The visuals are animated 2D and AI CG art, and the adult themes include fantasy, harem, and corruption.
The current build is v0.4, released on September 21, 2026, and development is ongoing. It runs on Windows, Linux, Mac, and Android in English, without censorship. This update rebuilt the game from scratch with a new engine and codebase, added position-based combat with manual and skill-based position swapping, and introduced a new lust system covering jealousy, loss of control at max lust, and pregnancy. Dungeons became branching maps with route choice, Act 1 is available, and the town was rebuilt with new location UI. The patch also added story and CGs, an inn for building relationships, 30+ animated scenes, 80+ items, a new boss, enemies, skills, and animations.

Draconium2026-01-13★★★★★
Good at a glance, DD but lewd is in fact a fantastic idea. But gameplay is simply to boring. Your just stuck in endless combat loop (which is the most basic and unthoughtful kind unlike DD). For anyone interested in…
The_Thiccness2025-11-05★★★★★
Deserves more than a 3 star average, one of the better AI Games, and quite enjoyable as a mobile game. I enjoyed it a lot more than I expected however it feels a bit easy and the AI hentai scenes…
Voronc2025-11-03★★★★★
I'm 99% sure most of the 5 star reviews here are fake, because this game is below average at best, people comparing this to DD and saying it's a good porn copy are either crazy or have never played DD…
