Invaders

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

The player controls a spaceship at the bottom of the screen that moves laterally and fires vertically. A group of alien ships move as a group across the screen left to right and back, moving down slightly with each return trip. Three barricades provide protection from alien fire. The goal is to shoot all alien vessels before they reach the bottom of the screen. An alien UFO intermittently flies across the top of the screen for bonus points. The player starts with three lives and it's game over when all are lost.
