Cyberpunk 2077 is an action role-playing video game played from a first-person perspective. The story of the Phantom Liberty expansion is set in a new district named "Dogtown", which has its own unique characters, quests, gigs, and items. Phantom Liberty introduces a new Relic skill tree with nine abilities. To unlock new Relic skills, players must progress the story of Phantom Liberty, or access restricted data terminals found in Dogtown. The expansion also raises the level cap to 60, and adds new weapons and vehicles into the game. New quickhacks are also added to the game, allowing players to perform actions such as air dashing, seeing through walls, or changing V's appearance on the fly. Vehicular combat is also added, allowing players to drive cars armed with missile launchers and machine guns. Depending on the player's decision, a new ending for the base game will be unlocked.

The Phantom Liberty expansion was marketed together with and released in a similar time frame to update 2.0 for the base game, which significantly overhauled the existing perk tree.

Cyberpunk 2077 takes place in Night City, an American megacity in the Free State of North California, controlled by corporations and unassailed by the laws of both country and state. Players take on the role of Vincent / Valerie, also known as "V" (Gavin Drea / Cherami Leigh), a mercenary who was killed, then revived by an experimental Arasaka biochip called "the Relic", and ends up with a digitized engram of legendary rock star Johnny Silverhand (Keanu Reeves) existing within their mind. Together, V and Johnny search for a way to prevent the Relic from killing the former and replacing their mind with Johnny's.

In addition to some of the characters from the main story, the Phantom Liberty expansion features additional appearances by the following characters: Song "Songbird" So Mi (Minji Chang), a netrunner working for the New United States of America (NUSA) Government; Solomon "Sol" Reed (Idris Elba), a Federal Intelligence Agency (FIA) operative who works for the NUSA Government as a sleeper agent; Rosalind Myers (Kay Bess), the President of the NUSA; Alena "Alex" Xenakis (Yvonne Senat Jones), Reed's former FIA partner who went undercover in the Dogtown district of Night City as a bartender; and Kurt Hansen (Eliah Mountjoy), leader of the Barghest militia who controls Dogtown.

Following a venture into the Pacifica district of Night City, the mercenary V is contacted by Song "Songbird" So Mi, the aide of NUSA President Rosalind Myers. She explains that their aircraft has been hacked and is about to crash in the lawless district of Dogtown, ruled by warlord Kurt Hansen. Songbird asks V to help rescue Myers in return for her assistance in preventing the Relic from destroying V's brain. V saves Myers and escorts her to a safehouse, but they lose contact with Songbird on the way.

With Songbird missing in action, Myers asks V to contact Solomon "Sol" Reed, a NUSA sleeper agent, for help. Reed successfully extracts Myers from Dogtown, after which Myers gives V and Reed a new task: rescue Songbird. Reed enlists the aid of fellow agent Alena "Alex" Xenakis and netrunner Slider in order to locate Songbird. Slider reestablishes contact with Songbird and is shocked to learn that to contact V she has been going beyond the Blackwall, the firewall that protects the world from rogue AIs, artificial intelligences that are hostile to humanity. Songbird tells V she has been captured by Kurt, while Slider is killed when the Blackwall overwhelms him.

Reed reveals that Songbird has been probing the Blackwall under Myers' orders, which is prohibited by international law. V and Reed infiltrate a party held by Kurt and meet Songbird, who explains that her mind is being corrupted by the entities from beyond the Blackwall, and a device in Kurt's possession called the Neural Matrix can cure both her and V's conditions. She sets up a plan to steal the matrix from Kurt and escape, while Reed and V deduce that Songbird orchestrated the plane crash as part of a deal with Kurt, which she later confirms. Reed resolves to rescue Songbird anyway, giving V a device that will knock her unconscious. Meanwhile, Songbird contacts V separately, asking V's help to escape from both Kurt and the NUSA. V, along with Alex, again infiltrates Kurt's headquarters and is then faced with a choice: help Songbird escape, or betray her so that Reed can take her into custody.
