So I've played through this game on all three difficulties, trying to get all the achievements (almost there, but now I have to restart on Normal 'cuz I missed Blast Wave/Rampage, sigh). I've enjoyed a lot of it, but one thing I find kinda unsatisfying is the ending. I love the credits, but the end of the story kinda leaves you hanging. You meet the super powerful alien, and then--what? It never shows what happens next. Does this bother anyone else? Do people think they're setting themselves up for a sequel?
