You are a resident of an underground city. Your task is to ensure security in one of its many sectors.

Recently, a team of miners in the neighboring town of Shakhtogorsk managed to unearth something unusual. A geological survey team from your sector was sent there to learn more about the discovery.

For a long time there was no news from the team, and then suddenly your city began to receive strange messages. For the first time in many years, the security systems have been brought to full combat readiness.

Manage the complex

Put yourself in the role of a security-system operator. At your disposal are a terminal and a map of the complex for locating and neutralizing dangers. To survive, you will have to act quickly and manage limited resources wisely.

Listen

The atmosphere is built around detailed sound design. You can hear everything happening beyond the concrete walls around you. But be careful — some sounds can be truly terrifying and dangerous.

Watch

Watch your surroundings carefully so you don't miss a threat. Devices like radar can help you detect danger before it's too late.

Enter the commands

Using terminal commands, you can configure and repair devices on the network.
