This is a 2 player version of Space Fleet. The 2 spaceships cooperate to clear the levels by shooting all the enemy ships. Player 1 moves left and right with the arrow keys and shoots using up arrow key. Player 2 moves left and right with the a and d keys and shoots with the w key. Warning: The two players cannot shoot at exactly the same time.
