The game cartridge and box shapes as well as quality in graphics and box art are identical to AV Artisan's previous titles Funny World & Balloon Boy and Mallet Legend's Whac-a-Critter, both published by Realtec. Earth Defense was also rare in that it was a simultaneous 2 player vertical scrolling shoot 'em up on the Genesis which primarily featured single player shoot 'em ups. The player takes on the role of a jet pilot assigned to liberate five world continents from a technologically advanced army.
Weapons
Players had two different types of weapons to choose from during combat. A vulcan/spread shot weapon and a wave/beam shot weapon. Rather than possessing bomb-like items, the players had a shield item that made the ship temporarily invulnerable.
Compatibility Issues
The game cannot be played through a Sega 32X. The game must be put directly into the Sega Genesis' cartridge slot. When the game is inserted into a Sega 32X, the RealTec logo will show up, but the Sega Genesis will keep resetting itself. The game will not run at all on the Majesco Sega Genesis 3.
