With the most recent update, Jbird stated that there were new codes added to the sub keypad. While an exact number would be nice, I enjoy the mystery. I have only found one new code, but I'm hoping others have found some new ones. I found the code "PACK" on a shipping container inside the final boss arena. When putting that code in, you get a bonfire sale. I cannot confirm this, but after putting that code in, you might have more time inside the sub before you get ejected.

What new codes have you found?
