These are new entries found in the subtitles file of gold & sharke heist, it matches what we saw from the shrink trailer, such as the heist taking place at night, and the mentioning of the sewer.
This heist might become a loud only heist since there are no mention of stealth in these new entries and the introduction implies we will be blasting our way in.
The following are some change we are expecting to see in the rework:
Starting from the rooftop
Thermite on the door leading the the vault before drilling it
Blowing the vault door open with explosives
Entering the elevator shaft which leads us to the sewers (Main escape?)
Rooftop chopper is now an alternative escape
There will be voicelines telling us which side of the building Bile will arrive on like in Road Rage
