"You command the BATTLE WAGONS!
Your mission is to command a squad of formidable BATLLE WAGONS... ground-based, highly mobile fortresses that are earth's last defence against the dreaded Sonic Invader from a far solar system.

The ruthless Sonic Invader with his tight formation of deadly Masque fighters has attacked thousands of planets all accross the galaxy and never tasted defeat. Only you can save the earth."

Sonic Invader was the Space Invaders clone from Video Technology. It was available for the Creativision console (and compatible systems) and for the Laser 2001 which was in fact technicaly compatible with the Creativision. Thus the two ports must be identical.

Sonic Invader was also a table top electronic game from Video Technology.

The game offers 16 variations, including 1 player mode, 2 players (competitive or cooperative), 4 players (two teams of two players), invisible mode and fast mode!
