Spoiler alert- Geralt regains his memory after the fight with dragon

The Witcher 2: Assassins of Kings is a 2011, action role-playing video game developed by CD Projekt Red, based on The Witcher series of fantasy novels authored by Andrzej Sapkowski. It is a sequel to the 2007 game, The Witcher and the second main installment in The Witcher's video game series. It was released for Microsoft Windows, Xbox 360, OS X, and Linux.[7]
The player directs the actions of Geralt of Rivia, a monster hunter known as a Witcher. The fantasy world in which his adventures take place owes much to Polish history and Slavic mythology.
The game was both a critical and commercial success, selling over 8 million copies,[8] by September 2014. The third installment in the series, The Witcher 3: Wild Hunt, was released in May 2015.
The Witcher 2 includes a stealth mode in certain parts of the game, where players must remain undetected as they make their way to a certain objective. Players have the option of stunning enemies if Geralt manages to get behind them, but the player may choose to take a less subtle approach and engage the guards in combat.
