46. Target Earth
Cheat: All Weapons
Target Earth is one of the hardest games on the Genesis, but worthwhile if you're a fan of anime-styled mech shooters. This code is worth trying out just for the challenge of unlocking it. To get all the weapons, you need to make a beeline for the boss at the other end of the first level without picking up any weapons or destroying anything. You'll know you succeeded when you've beaten the level with over 2800 points. Now you can enjoy the rest of the game with solid firepower.
