Characters : The Guardian of Light stars Lara Croft, a fictional English archaeologist and Totec, an ancient Mayan warrior and leader of the Army of Light. An evil spirit called Xolotl is the antagonist. Some of his minions that he makes come to life include: giant spiders, demon like creatures, and huge trolls. Lara is again voiced by Keeley Hawes and Totec is newly voiced by Jim Cummings.
Plot : Two thousand years ago in ancient Central America, a battle was waged between Totec, the Guardian of the Light, and Xolotl, the Keeper of Darkness. Totec's army was defeated when Xolotl used the mirror of smoke to unleash hordes of ghastly creatures that fought on his behalf. Totec survived the battle and found a way to defeat Xolotl, imprisoning him in the mirror of smoke and becoming its immortal guardian in the form of a stone statue. In the present day, Lara Croft reads of the legend and attempts to find the mirror. After a long and dangerous journey she is successful. While examining the mirror, she is caught unaware by a band of mercenaries. Led by the local warlord, they had followed her into the temple. Unknowing or unbelieving of the curse upon the mirror, the warlord takes it from Lara. His reckless handling of the mirror releases Xolotl. The stone statue of Totec comes to life and warns Lara that Xolotl must be stopped before the light of dawn. Depending on the number of players participating, Lara and Totec either join forces or go their separate ways to try to stop Xolotl.
