Phantom Liberty is the only DLC for Cyberpunk 2077, so I'll skip a lot of things that article covers. Phantom Liberty takes place in Dogtown, a section of Night City that's next to Pacifica. Like Pacifica, it was meant to be the rich part of town, but something went wrong, and it became a half-built slum. It's home to a gang named Barghest, named after mythical hell dogs, so they named their territory Dogtown. (To me, this is a Witcher reference.)
You can't complain about this anymore. It's perfect!
