The Nightmare is a downloadable content release for Shadow of the Tomb Raider, developed by Crystal Dynamics and released in 2019 for PlayStation 4, Xbox One, PC, Mac, Linux, and Google Stadia. The expansion places Lara Croft inside Croft Manor for a trial in which she confronts familiar enemies and fallen allies. Its central challenge tomb, Howl of the Monkey Gods, can be completed in either single-player or cooperative play and rewards a new weapon upon completion. The DLC introduces several additions to Lara's arsenal and wardrobe. The Scales of Q outfit doubles resistance to melee damage, while the Grip of Fear axe improves climbing efficiency and increases the likelihood of knocking enemies down for extended periods. A new skill, White Breath, releases a hallucinogenic vapor cloud on impact that causes poisoned enemies to turn on one another. The update also makes five campaign tombs available in Score Attack and Time Attack modes.

Storyline

Lara Croft walks in on Uchu and Jonah Maiava swapping scar stories. When Uchu asked Lara to share hers, she brushes the subject off fast. Jonah then asks about Uchu's face scar. Uchu tells them about a poison that could help the rebellion, and that the scars were from his ultimately failed attempt to get it. To obtain the White Breath recipe, one must take the Path of fear alone. Lara offers to get the recipe. Lara follows the path and finds a woman on it, who doses Lara with the White Breath. Lara hallucinates about her family, and friends getting killed, and finally sees herself as the cause of it. She overcomes the effects of the poison, and presses onward to the trial, which held the recipe for the White Breath. Lara returns to Paititi and gives the recipe to Uchu. Jonah still curious of the full story behind Uchu's scar asks about it, but Lara now knowing what the Path of Fear meant diverted the question.
