Tomb Raider: The Angel of Darkness is a 2003 action-adventure game developed by Core Design and published by Eidos Interactive for PlayStation 2 and Microsoft Windows. A Mac OS X port was developed by Beenox and published by Aspyr the same year. Acting as a direct sequel to Tomb Raider: The Last Revelation and Tomb Raider: Chronicles, the storyline follows Lara Croft as she attempts to clear herself of being the suspect of her former mentor Werner Von Croy's murder while investigating the activities of a black magic cult. The gameplay follows series tradition, with Lara navigating platforming environments while incorporating stealth and character growth elements. The game's development began three years before its release. The intention was to create a different game from previous entries in the franchise, one that could compete better with newer action games and fully exploit the potential of the sixth generation of gaming platforms. It was also planned to be the first in a new trilogy of Tomb Raider games released for the new generation. However, development was fraught with difficulties, which led to the game being delayed twice and numerous planned sections of the game were scaled back in order to meet deadlines. Despite selling 2.5 million copies worldwide, Tomb Raider: The Angel of Darkness received generally negative reviews from critics; while some praise went to its narrative, critics faulted the game for its poor controls, camera and numerous technical issues. In the aftermath of the game's release, the planned trilogy of games was scrapped, and the development of the franchise was transferred to Crystal Dynamics for the next entry in the series, Tomb Raider: Legend (2006).
