Lara Croft and the Guardian of Light is an isometric platform action video game developed by Crystal Dynamics and published by Square Enix for the PC, PlayStation Network and Xbox Live Arcade as part of the Tomb Raider series for digital download. Unlike previous games in the series, the game does not carry the Tomb Raider brand and will have a heavy emphasis on cooperative gameplay, both online or locally. In the multiplayer, players will take the role as either Lara Croft or a 2,000 year old Mayan warrior named Totec. They will have to work together in order to stop the evil spirit Xolotl and retrieve the Mirror of Smoke. A single-player campaign mode will be available that will not include the non-playable character AI following or helping Lara. Guardian of Light will use the same game engine as Tomb Raider: Underworld, and will include modern visuals and physics. The video game was shown at E3 2010 on 14 June and was released for the Xbox Live Arcade on 18 August 2010, but online co-op gameplay will not be enabled until 28 September, the day of the PC and PlayStation Network release.
