A spacecraft called Not Alone is already in the upper layer of the stratosphere and begins to enter the ionosphere when you suddenly realize that you are on board all alone. Do not panic, you should try to find crew members and return to the flight control panel. Along the entire perimeter of the spacecraft are boxes with weapons. You should stock up cartridges that will help you out in the event of an attack by space invaders. Go from one compartment to another with automatic doors. Watch for the shadows, maybe you are hunting a terrible animal, which you have to eliminate in the near future.
