From the developer:
A game set in the future, where you are the commander of a squadron of spaceships. You will be sent on one of 30 different types of mission, ranging from protecting a convoy, to attacking an enemy starbase, to defending Earth. Combat is carried out using four different types of missiles which home in on the nearest target, so you have to be careful not to destroy your own friends.
