I'm the same as Stoked - just beat the game but didn't quite understand the ending. If there's a site that explains it or something, that'd be great!
Also, in the exact oposite as Stoked, it said I "zero" starred the final boss, which I find almost impossible as I beat him really quick. Rav/Rav/Com to stagger to start, immediately did "Army of One" and pounded on him. Then had to heal once quick, and then Rav/Rav/Com again. Beat him on the second stagger...can't believe that should be zero stars. You must have to beat him in like 20 seconds to get a 5 star...
