Lara Croft has accidentally triggered an apocalyptic event by raiding a Mayan tomb. Now she must find the legendary city of Patiti in order to set things to rights. Her job is made harder by the paramilitary organisation, Trinity, who seem to have their own reasons for wanting to let events play out.
Along the way, Lara Croft explores the depths of wild South American forests and mountains, hunting beasts, finding hidden tombs, solving puzzles, and trading with and aiding villagers along the way.
She must also battle Trinity's soldiers as she strives to reach Patiti before them, needing to work out how to stop the apocalypse that she has accidentally triggered.
