Phantom Liberty is how you do DLC. It compliments but never erases the base game's experience. In fact, for me, Phantom Liberty's shorter, more concentrated length, themes, lighting, sound design, story, and just about every aspect completely eclipses the base game. Phantom Liberty ditches the petty grudges of mega corps and rebellions and ups the ante to the big leagues with assassination attempts on the President of the New United States of America (NUSA) and undercover operations against the tyrant of Dogtown.
I cannot praise CD Projekt Red enough for just how deftly they weave espionage, thriller, and, surprisingly, horror so effortlessly that other developers should look on and take notes. Stealth, psychology, battles of sheer will, Phantom Liberty showcases newcomers Idris Elba (as Solomon Reed) and Minji Chang (as Songbird) in such spectacularly heartbreaking stories that will have you by the balls (or ovaries, and, ew, I've made myself uncomfortable).
Twists, turns, you'll be exposed to it all, and, just when your nose is pressed right to the screen, CD flips from spy thriller to techno-horror and your expectations for both will never quite be the same (for this, I recommend siding with Reed when it comes, you will not be sorry). Update 2.0 for Cyberpunk 2077 was an apology for the broken state it released in, but Phantom Liberty is a promise to try and avoid those mistakes in the future. If it weren't DLC and 2023 weren't so packed with fantastic gaming experiences, Phantom Liberty would be a serious contender for Game of the Year. Heck, in some places, it still might grab that title.
