About the Game

A Pacifist Immersive Sim

Lost Under Space

After crash landing on an uninhabited desert planet, you wake to discover a hidden city hiding below the surface.
A city that you got tossed right to the bottom of.

Discover the inner workings of the city, find secrets no one was supposed to see and make unlikely alliances as you work your way up through the city and escape back to outer space

A Game of Cats and a Very Persistent Mouse

Finding friends in the Repossession Union, your means of getting up to the surface requires you getting into places people don’t want you in.
This is an above-board operation, so Do no harm unto the guards, no harm unto you
Use every trick in your arsenal, be as slippery as you can.
Never having a guard lay eyes on you, or raise every alarm, get chased by every guard, and use the chaos to your advantage.

A Tactile City

The city of November is a vertical city designed for form over function. When a city has to sustain itself, every aspect of its operation must be accounted for, down to the materials used for the walls.
As such, the city of November has been constructed with attention to detail on its function and its interactivity between its complicated systems, allowing for a whole host of ways to solve problems.

Ghost in the Circuits

Running through the veins of November lies an otherworldly presence. While the intricacies of the city are rooted in logic, many aspects leave even the locals without clear explanation. As your time in November comes to an end, what conclusions will you draw?
