Which is free for Season Pass holders, or available as a single DLC purchase. Slightly different to "New Moves Packs" in that this is narrative-specific content, but paid-for post-release content, nonetheless.

Here's the official skinny:

In “The Pillar,” players will venture into the game’s newest challenge tomb known as Path of Huracan to discover the truth behind the legend of the Maya apocalypse. To reclaim an ancient treasure, Lara Croft must defy the treacherous storms of an all-new challenge tomb, all while fighting the forces of Trinity.

“The Pillar” offers new customization options with the Sinchi Chiqa Battle Dress outfit, which reduces damage from projectile weapons and allows additional ammo to be crafted. The Oathtaker’s bow deals greater damage to armored enemies, and the A Thousand Eyes skill allows Lara to use Survival Instincts when moving through tree canopies or concealment walls.

The first DLC release “The Forge” is also available now, and is playable in either co-op or single-player. Tombs from the main campaign, “Judge’s Gaze,” “Underworld Gate,” “Howling Caves”, and “Path of Battle” are all now playable in Score Attack and Time Attack modes.
