Quoted from Phbooms:Yeah it's weird because there's actually 4 regular Hoth modes and only 3 on all the other "planet" modes.
Yeah, I don't get this either. The playfield only has inserts for "I, II, and III" and then the planet insert. How do you know if you're in this fourth mode? what's the indication (there isn't an insert for it)? If I played the other three (technically 2 since hoth I is already complete) I would expect to go direct to the planet MB wouldn't I?
