Shoot 1UP DX is a retro top-down shooter of the "fly and shoot" type, which is an improved version of the game Shoot 1UP. The main feature that sets it apart from most representatives of this genre is that each new power-up adds another combat unit under your control. Thus, your screen can grow an entire armada of up to 60 ships if you play in co-op mode with a friend, and up to 30 if you conquer the campaign solo.
