The cold came without warning.

Within days, Ashvale became a frozen city. Streets emptied, buildings went dark, and the last remaining sources of heat began to fail.

You wake up with only a few supplies and one goal: survive the cold. But as you explore the abandoned city, you begin to find notes, clues, and traces of something that happened beneath it.

The temperature keeps falling.
And the deeper you go, the more you realize that the cold may not be the only thing you need to fear.
