Black Iron, a state-of-the-art penitentiary located on Jupiter’s icy moon Callisto, is overrun with hordes of infected inmates. As a modest prison guard your job is simple – get to the last escape pod and get out alive. But you aren’t the only survivor looking to escape. Your rivals – a deranged custodian, a violent gangster, a maniacal lunch lady, and more – can’t wait to step over your corpse and save themselves. Only one of you can make it off the moon – make sure it’s you!
