The cinematic action-adventure that forced Lara Croft to grow from an inexperienced young woman into a hardened survivor has been re-built for next-gen consoles, featuring an obsessively detailed Lara and a stunningly lifelike world. Lara must endure high-octane combat, customize her weapons and gear, and overcome gruelling environments to survive her first adventure and uncover the island’s deadly secret. The Definitive Edition of the critically-acclaimed action-adventure includes bonus content and combines all of the downloadable content from the Xbox 360 version.
