Star Defence

Star Defence is a 1–2 player arcade game for the Dragon 32/64.

The player controls a spaceship that can move up and down, change direction, and accelerate. The ship is armed with a laser gun that shoots directly forwards, and a limited number of smart bombs which destroy all enemies on the screen. The play area scrolls and loops laterally. The goal is to shoot all enemy vessels in the level to progress to a more difficult challenge. The players each start with 3 lives, and it's game over when all are lost.
