A vertically scrolling shooter from AV Artisan that has some compatibility quirks.
Earth Defense, which reads The Earth Defend on its title screen, was made by AV Artisan and published by Realtec in North America and Taiwan in 1995. This is an unlicensed cart, made without Sega's licence. It is a vertically scrolling shooter.
Before you buy
Reportedly the cart has to go straight into the console's cartridge slot. With a 32X attached the Realtec logo shows but the console keeps resetting, and it will not run at all on the Majesco Genesis 3. Loose carts sit below the middle of the unlicensed pack.
