Shadow of the Tomb Raider’s latest DLC adventure is now available as a download for $4.99 USD standalone or for free for players who have a Season Pass. You can find the release trailer below.

Titled “The Serpent’s Heart,” Lara must infiltrate an enemy fortress and face off against Kukulkan cultists, all the while staging a daring prison break to save of the lives of loyal rebels. Lara will also have to face the Slayer’s Gauntlet and navigate dangerous rapids in order to receive the power of the serpent god.

Players who complete the challenge tomb will be rewarded the Divine Bounty skill, which causes fallen enemies to yield more gold when looted. The Serpent’s Heart will also offer players the Dragon Scales outfit–which reduces fire damage, prevents stumbling and accelerates health regeneration–and the Serpent Lash bow, which will deal extra fire damage.

Additionally, the Thirsty Gods tomb from the main campaign has been added to the growing list of tombs available for Score Attack and Time Attack modes. The full list of tombs includes Judge’s Gaze, Underworld Gate, Howling Caves, Path of Battle, Temple of the Sun, San Cordoba and Ancient Aqueduct.

Shadow of the Tomb Raider is available now for PlayStation 4, Xbox One and Windows PC/Steam.
