In 2019, a virus was discovered that caused extensive mutagenic effects in the general population.
SkyCorp Global’s Research Division was the first to identify this virus, designating it VIR-819. The infection was pronounced and forever changed anyone it touched. Victims often underwent significant changes to their libido, frequently becoming sex-crazed. These glandular changes sometimes caused dramatic shifts in patient’s height, weight, even their gender. In the most extreme cases, the infected lost their very humanity itself as they devolved into monstrous animal-human hybrid creatures. It was clear that dramatic steps needed to be taken to protect our way of life.
This contagion spread like few ever had previously. With no cure in sight, the following year SkyCorp was awarded the Department of Defense contract to create a quarantine zone for the infected. The quarantine zone was hastily constructed, and with close partnership from the National Guard, all infected were forcibly relocated. To this day, SkyCorp continues the administration of the quarantine zone.
Due to this zone being a collection of largely underground facilities that were reappropriated for containment, the project has been colloquially referred to as ‘The Underworld.’ While uninfected citizens are technically permitted to visit The Underworld, it is heavily discouraged due to the risk of exposure. Still, occasionally a citizen will need to enter regardless. In that situation, we can only pray they will return human — or they’ll become a permanent resident themselves.
The Underworld is a text based transformation game for mature audiences including erotic content such as: furry, monstergirl, transgender, oviposition, lactation, and more. Along the way, you’ll meet a wide cast of characters across the three factions that each have their own ideology about how to deal with people different from themselves. Your actions will determine which faction achieves victory, and by extension, the fate of humans and hybrids alike.
The game is a work in progress
“I love this game so far! If I had two sentences to review this game and encourage others to give it a shot, it would be these two:
I used to be quite disinterested in slug girls.
I am now utterly and wholly interested in slug girls.” — Railby
“This game has truly been an enjoyable play through, the story is enjoyable, game itself is cross-platform because of flash, and the current variety of scenes and what can be done is really enjoyable.”
“10/10, would hook up with crazy dragon lady again.” — pyruvic
