Main character ASTRONAUTILUS suffers a space shipwreck and finds himself on a rogue planet. The new and unexplored world is home to many deadly creatures, and the environment is unsuitable for normal life. You have to travel under the icy surface, fighting with opponents and acquiring a variety of materials and resources that will help restore the functionality of the ship and get out of this world.

The spacecraft suffered minor damage, but the second problem is the complete lack of fuel. The central character moves through underground locations, finding the necessary materials and fighting opponents. The arsenal includes more than 8 types of weapons with their own characteristics. Each type of weapon has 2 upgrades that open up new types of attacks or increase characteristics.

On the way, the protagonist will face 60+ types of enemies. Opponents have their own characteristics, strengths and weaknesses. The environment is procedurally generated, as are the locations of enemies and upgrades. The combo system allows you not to stop when delivering attacks and using blocks. Successful risky actions are rewarded in different ways, helping you instantly destroy an enemy or overcome a trap.
