Wind Tunnels and Sand Worms

After the opening cutscene, move Gris to the right. She will gain the ability to jump after passing through a fog cloud.

Backtrack slightly to the left to find a pillar and a collapsed statue. Let Gris fall and get up without touching the controller to complete the 'First Stage of Grief: Denial' challenge.

Continue right, ascend a large rock, and collect the first pulsing light (Star).

Proceed right, jumping across crumbling platforms. Collect a second Star shortly after starting to climb a black mountain.

Continue to a large gap. You'll need more stars to cross.

Climb the stairs on the left to a leaning tower. Ascend the zigzagging stairs to the top. Your two collected stars will form a bridge to a smaller tower where you can collect a third Star.

Before returning to the gap, mount the first staircase of the leaning tower and jump left. Activate the Memento symbol to collect your first Memento.

Return to the gap. Your three stars will form a bridge. Cross it and continue right until you reach a crumbling stone hand. A cutscene will play, and you will complete the 'Red - A Color Has Been Brought Back' challenge.

Continue to a giant staircase leading to a temple. At the top, you'll see a pictogram.

Proceed past a blood-red tree. Your star companions will leave you to form a constellation.

Continue down the stairs and head right until you slide down a red mountain.

On flat ground, continue right to a black tower. Climb it to complete the Prologue.
