Jets'n'Guns/Lagoon

Communications with the Glutosians have informed you of the presence of a pirate base on Coldfoot Epsilon, an ice moon. Prepare yourself for a ground mission.

This level has an interesting boss. It's a huge, flying submarine (although technically, above water it would be called a supermarine), complete with torpedoes and all that. Fire your weapons at the front part, avoid the torpedoes, and bomb the top part when you get the chance. Should be pretty easy.
