Before you can hunt down the nefarious Dr. Cossack, you need to topple his eight robot minions. Why do all evil geniuses these days arrive on the scene with eight robots to do their bidding?
In many previous adventures, you couldn't visit a stage once you had cleared it, but that's not true this time around. You can visit a stage as often as you like, and you can keep what you find. This makes it easy to farm for energy tanks. It also allows you to have fun playing around with your favorite equipment in places where otherwise you couldn't.
Most importantly, it prevents you from missing a few hidden objects… but you don't have to worry about that, anyway. After all, you're following this guide!
