Project SEVER
Steam
A tempting offer: a short contract, generous compensation, and an expedition beyond the Arctic Circle. How could you refuse? Your task seemed simple - service the carrier of the mysterious Soviet sub named "Sever-3" (North-3). But fate had other plans for you: You volunteered to be a replacement for a sick staff mechanic on a mission, and as luck would have it, everything went wrong. Now you're trapped in the deep, lost in the ruins of an abandoned Soviet research complex.

Your only chance of survival lies in mastering the controls of this sophisticated submarine to uncover the secrets that have been buried here for decades. But beware, you are not alone in these dark waters.

The "Sever" submarine was built with the most advanced technology of its time. Decades later, some of the equipment looks old-fashioned, but others are still impressively advanced.

Use the holographic navigator to avoid getting lost in the Zone's labyrinths, the sonar to see your surroundings, and the underwater drone to interact with the outside world. And don't forget to monitor your power consumption, as the onboard nuclear reactor is prone to overheating.

Explore the ruins of a research complex built on the territory of an anomalous zone. As a result of a mysterious disaster decades ago, the entire complex was deserted overnight. Solve the mystery of what happened in the past, restore the chain of events as you explore the territory of the Zone, and find a way to get out of here alive.
