The Arena, From the Deep Guide - Horizon Forbidden West

First thing first, it's best to fight on the outskirts of the arena.

Because the fence can stop this annoying thing, it is not 100% defense but it can make all the difference.

Now for the actual fight.

Once you drop, don't attack right away as the snapmaws will likely start blasting before you can fire back.

So you have to run behind the fence on one side or the other.

The gist of the fight is this:

1. Every time you get near the machine, you have to use the weapon technique on it, if you have the energy. 2. Then shoot one salvo of bolts which make the machine enter a shocked state. 3. Once the machine is shocked, you have to keep firing with shock bolts.

Doing this the machine never leaves the state until dead.

Weapon technique.

Enter a shock state.

If the machine leaves the shocked state on you, you must feel overwhelmed. It's best to retreat for a bit and start the process again.

Whenever you have the time, reload the weapon.

Destroying the tide ripper without him leaving the shocked state is the same tactic as before.

He will never leave the shocked state.

Fence blocking the attack as mentioned before.

The last one is really easy again using the shock bolts to bore him down.

Note that the order by which you destroy them can depend on your situation, who gets near you first, second.
