Vault

personal vault??? wut??? There is no personal vault in this game. There's a vault hunter's outfit and a pistol from dlc....if that's what your talking about.

If it is concerning vault upgrade (not the full vault edition)

You MUST BUY THE full game gamesharing won't work with vault upgeade you MUST OWN the base game digirally

If you have a disk vault wont work

Go to the multilayer menu and select Vault. There will be three options on the new menu. Online Vault, Friend's Vault and Theatre. Just select the top option.

Fallout 3 was set in a vault inhabited by vault dwellers ?? Your character (The vault dweller) was issued a PIP boy exclusively used by vault dwellers from Vault tech. Fallout New Vegas was set in the South West with a character called the courier who had
no affiliation or connection to the vault genre, but mysteriously has a PIP boy on His or Her wrist. In Fallout 3 there is a Vault tech headquarters, but nothing remotely present in New Vegas. I think Rage is correct and You are sadly mistaken again. No
offense, just fact.

speaking vaulting over a rail......whats with the vaulting-in-place exercise?...you and your buddies approach the same short fence/wall and they all vault over just fine, but for some reason XBL decided you needed a workout and it doesn't let you vault over
the same obstacle your friends just vaulted over and instead you just stay there stupidly vaulting in place....the animation is the same, but you land where you started ...what a treat
