Cyberpunk 2077's Phantom Liberty expansion features a unique Easter egg that offers players a glimpse into the history of CD Projekt Red, the game's development company. Founders Marcin Iwi?ski and Micha? Kici?ski appear in Dogtown, the central location of the expansion, selling Braindances, interactive virtual reality experiences that symbolize key moments in the company’s past.

Each Braindance represents a correlating moment in CD Projekt Red's history and is priced in Eurodollars to denote the year of that event. For example, 'The Snitcher' is available for 2007 eddies, reflecting the release year of The Witcher.

Other Braindances include references to Iwi?ski's past selling imported games in Poland, the Polish localization of Baldur's Gate in 1999, the release of open beta Gwent in 2017, Thronebreaker’s launch in 2018 (a role-playing game related to Gwent), and finally, Cyberpunk 2077's debut in 2020. Every Braindance possesses a distinct description, often humorously alluding to their corresponding events or products.

The Phantom Liberty expansion was released on September 26, shortly following Update 2.0. This game-changing update invigorated Cyberpunk 2077 with new features such as improved AI and a revised perk system. The update and subsequent expansion led to a surge in the game's popularity on Steam.

IGN, in its 9/10 score review, acknowledged the marked improvements in the game, stating that the expansion has turned the tide for CD Projekt Red’s future RPG, especially post the 2.0 update and the anime adaptation, Cyberpunk: Edgerunners.
