Borderlands 2k Games The basis of the game is false! No Vault. Everyone talks about it, but its not there! Internet

Borderlands, the after market game following the coat tails of Fall Out 3.  Cool cartoony graphics.  Check.  Lots of Guns.  Check.  Interesting introductory storyline.  Check.  Actually living up to the idea of the game and storyline.  NO CHECK. 

I liked this game when I started.  I thought, yeah, trying to play off the Fall Out 3 line, but its an interesting spin.  Well, much to my surprise and unhappiness, THERE IS NO VAULT!!!  There's some big one eye'd monster, like in my pants, but no hot a*s release when you beat it!!  WTF?!  Its a jip and its a poor ending to what could have been a really good game. 

If you've played it, please, let me know what you think.  Thank you.
