"Stellar Sphere" is a scifi sport and action game, mainly set in space and in zero gravity. The rules of this game are tremendously simple: you must move with your ship through an area, look for a sphere, capture it, and throw it over the wormhole that is active. That's all. Almost.
The cloak is active in this image. If the player activates the cloak while the infrared system is running, the combination gives this effect. The target is a Pyramid, a ship designed to steal the sphere so you can't score. You'll have to destroy it at once.
