Model A Invaders

Model A Invaders is an arcade shooter and a clone of Space Invaders. The player controls a laser cannon that moves horizontally along the bottom of the screen. The objective is to eliminate rows of descending alien invaders before they reach the player's position.

The game includes four gameplay modes: standard, fast missiles, fast invaders, and a combination of fast missiles and fast invaders. IJK Software released two distinct versions of the game—one for the BBC Micro Model A and another for the Model B. Due to the limitations of the Model A, this version uses the BBC Micro's Mode 7, resulting in reduced graphical detail.
