Orbital is a puzzle shooter developed by Bitforge for the iPhone, iPod Touch, iPad and Windows Phone.
In Orbital, players fire balls that bounce against the wall and expand. Depending on where they stop bouncing, their size varies. For example, if the ball ends up in a corner, it will be relatively small. If it ends up in an open space, it can be huge. Players fire the cannon from the bottom of the screen and if thee ball bounces back, crossing the red line that's in front of the cannon, it's game over.
Once the ball expands, a number appears in the center of it. This number corresponds to the number of times that players must hit it before it disappears. Each ball starts with the number 3 in the middle. The fact that balls can only be eliminated with another ball creates an endless chain of balls. The way that balls are eliminated depends on the game mode.
Here, each ball serves as a planet with its one center of gravity. When players fire the ball, it will be attracted to the other balls. The strength of the gravity depends on the size of the ball; balls are attracted to bigger balls, this means they can be eliminated faster.
A mode with no gravity in play; players only must hit the other balls to make them disappear.
Super Nova Mode
Players directly control the canon. A laser shows where the ball will end up, but since there's gravity in play, players must take into account that what they're being shown may not be the actual path of the ball.
Two Player Mode
A mode that allows two players to play together.
