What's the vault code?

733197 - 438. The first few numbers are given to you when you inspect the body at the Q-COS station. If you go in to scavenge supplies you get 700 idium free, or some free idium crystals (random). Then you have the option to go to the vault or leave. Then options to inspect the turret, the body, and read the first few numbers of the code. You are only asked to enter the last 3 numbers.

Once you enter the vault you get to unlock another place. So you get the option to go to the corporate battlefield, Tortuga station (very hard) and vivid nebula (hard).

Gamble with the pirates in Tortuga enough and you'll be offered a chance to win an unburnt keycard with the code. Every visit the vault after that and you'll have it automatically.
