Rise of the Tomb Raider's third and final add-on, Cold Darkness Awakened, will be released March 29 on Windows PC, Xbox 360 and Xbox One, publishers Microsoft Studios and Square Enix announced today.
The downloadable content introduces a new mode in which Lara Croft heads to an old Cold War-era research facility and finds that a breach has allowed a contagious illness to escape into the surrounding area. The deadly disease turns Trinity soldiers into "bloodthirsty killers who thrive on carnage" — aka zombies — and Lara has to use every tool at her disposal to survive as she attempts to re-seal the base.
Cold Darkness Awakened is the last piece of Rise of the Tomb Raider's $29.99 season pass. Players who don't own the season pass will be able to buy the DLC pack on its own for $9.99 on Steam, the Xbox Live Marketplace (Xbox 360), the Xbox Games Store (Xbox One) and the Windows Store.
