Orbattle truly is a battle of orbits
The oddly named Orbattle not only combines two words into its title, it also combines two seemingly different elements into its gameplay. Orbattle takes the physics/gravity/strength gaming principle of games like Bowman, and applies it to an outer space theme. The result is a tough (too tough?) battle between you and a computer enemy (or a friend) to destroy the other first.
You select an angle and power for your missiles. However, you have to take into account the way in which the gravitational pulls of several planets will affect your shot. The downside being the computer enemy seems to have paid far more attention in physics class, as it often only takes a few shots for him to lock-on and destroy you. Play a friend instead for a more even match.
