The thirteenth chapter of Death Stranding begins after completing order #68 - Crybtobiote Delivery: Capital Knot City Isolation Ward. This page of the guide to Death Stranding focuses on the ninth chapter.
[Order No.69] Go to Her Beach
Where the mission begins: Complete chapter 12.
This mission starts on the beach. Your task is to find Amelie. This will complete the chapter.
Remember not to enter the water. Remember that Sam can't swim. The main character can drown which will force you to repeat the mission.
Keep running to the left, along the shore, until Sam decides to stop.
If he sits on the ground, don't order him to get up. This will trigger a cut-scene.
When you find Amelie, the game will suggest that you have a choice. Remember, however, that there are no choices in Death Stranding. We have described this aspect in the FAQ section.
If you allow the woman to enter deep water, the game will force you to go through this mission again.
You can't stop her with a weapon. Bullets won't hurt her.
To save her, you just need to hide the weapon and hug her. This completes the mission and starts the last, fourteenth chapter.
