There are 7 stages (not including Meteor X) that you can romp around in. Here's the lowdown of these stages. (Note: Level refers to cliffs and such which make for higher altitude.)
-Tokyo 2: This is a one level place with LOOTS of buildings. It's easy to get your rage meter up in this place.
-Glacier a/b: This place has many levels annd lots of buildings to blow up. Careful! The ground is slippery.
-Nova a/b: Planet Nova-10. This place also has stuff to destroy, and lakes place on multiple levels.
-Meteor-Z: No, not Meteor X. This is Meteorr Zeta. this is a lot like Nova-10, it just looks a tad different.
-Moon Base: The most fun stage! This place is barren, has only one level and has low to no buildings. However, that is compensated for the extremely faboo (did I just say "faboo"? Oh, well) LOW GRAVITY! YEEHAH!
