Star Defender II is a top-down horizontally scrolling shooter game. The
player with his single spaceship must move left and right, firing on the enemy
ships that appear. Successful destruction of enemy vessels increases the
score. Some enemies drop power-ups when destroyed which include upgrading the
primary weapon, granting missiles (regular and homing) for the secondary
weapon, time freeze, nuclear bomb which destroys everything on the screen and
a shield which protects the player for a short time. Without the shield, enemy
fire will destroy the player’s vessel and cause them to lose a life.
