The UPN v0.3 Tentacle Edition

In case this is your first time playing these titles, you should understand right off the bat that UPN isn’t a typical IT term. UPN means “Underworld Porin System”, and it’s all about a wild, filthy network down in the underworld.

Ruling over this wicked system is the goddess Crania, the goddess who controls death and unrelenting lust. But Crania isn’t some distant deity. Her stunning, customizable form is her secret weapon, something you can adjust a bit once you start interacting, she relentlessly fucks any demon or creature she encounters.

It’s not just mindless fucking. Every filthy session rewards her with unique money, helping her maintain control over the shadowy realm. On top of that, she splurges on some wicked sex toys.

The latest version turns up the heat by adding twisted tentacle scenes, mixing the familiar monster fucking with an alien, writhing touch. Get ready to plunge deep into this depraved universe, this is where the real fun begins.

Take charge of Crania’s irresistible allure, tweak her enticing figure, while ravaging endless waves of horny demons and slimy tentacle beasts, start playing now and let the Underworld Porin System drag you into a world of pure ecstasy.
