Fly around in 3D space and repair supercomputer modules!
Earth is under attack! Alien forces want to kill all 10 billion humans!
Humanity is prepared: a sophisticated defense system controlled by supercomputers with modules arranged in the shape of a Menger sponge.
But the followers of a doomsday cult were able to infiltrate the defense initiative and sabotage modules in every supercomputer.
Your job: repair these modules by shooting repair torpedoes at them.
