Alternatively, you could stage an ambush by placing a few traps along the convoy’s path.
Once the convoy is defeated, loot the remains of the Bellowback - the quest should update.
Return to the tall building where the NPCs you met recently are staying.
so you can obtain the second part, you must jump into theflooded elevator shaftand dive into the water.

It also doesn’t require manual activation - Aloy puts it on automatically when needed.
Swim to the very bottom and start exploring the flooded city.
Make use of Focus, which serves as a sonar of sorts.

Travel in the direction of the first node.
Use plants at the floor as hiding places and avoid being hit by machines by dashing (CIrcle).

You should also read through info regarding its armor elements and the attacks they grant him.
Use the ammo types the Tideripper is weak to.

Despite its size, the Tideripper is quite agile.
Focus on running around the arena and keeping your distance, dodging to the side whenever you better.
After winning the battle, it’s possible for you to optionallytalk to Morlund and his team.
