Goodbye, Night City ghosted in old-school style: no red eye icons and no noises heard by enemies, the environment left undisturbed, enemy equipment returned to its original state (cameras at 2:10). All the usual restrictions still apply: no kills or takedowns, no quickhacks, no cyberware.
(And to be technical, I didn't return the door at 2:02 to "original state" because the game doesn't allow you to relock unlocked doors. If I tried to leave the holding pen by jumping to the 2nd floor Bruce would have unlocked it anyway.)
Goodbye, Night City is an SOS: Merc Needed side gig you get from Dakota Smith, where you have to rescue a smuggler named Bruce Welby imprisoned in Militech's compound. The optional objective only asks you not to kill any Militech personnel; staying stealthy isn't required.
Rules:
No quickhacks
All attributes left at 3 (minimum)
No perks
No extra cyberware in any slots besides the ones I have installed by Viktor: eye, hand, OS
Very Hard difficulty
