Armored Core 6 Sea Spider Boss Guide

Want to complete the Ocean Crossing mission in Armored Core 6, but Sea Spider is preventing you from getting into the cargo ship? Don't worry, I'm here to help.

Armored Core 6 features many bosses in Chapter 2, and Sea Spider is one of them. You will encounter Sea Spider before boarding the cargo ship during the Ocean Crossing Mission. Up until this point, you took down every enemy with ease. The Sea Spider in AC6 will be the first to challenge your skills seriously.

When you face off, don’t wait for the right moment. Here are some helpful tips that you can use to beat the Sea Spider:

  1. Keep a mobile build to enable quick and constant movement to dodge his attacks.
  2. Stay in mid-range to be aware of the attacks.
  3. Use miniguns (x2) and songbird rocket launcher (x2) to drop its HP while staggering it to pieces.

Use a Staggering Attack Strategy

Fire your arms and shoulder weapons at Sea Spider. In the beginning, you will also take damage, but a while later, you will start to dominate and stagger him. Once he is staggered, your attacks will deal more damage.

Learn Sea Spider’s Attacks

If you observe Sea Spider’s Attacks, it has no weak points and employs double layers of charged laser and melee slam as primary attacks. Therefore, you need to remain agile to dodge attacks. The easiest way to dodge attacks is to continuously rotate around the boss, as it can perform melee attacks from the turret on top.

In the first phase, Sea Spider remains on the ground, so to attack him, you must stay in mid-range till its stagger is broken. If you notice the boss’s pattern, it has single attacks that can deal massive damage. So, you must read its movements.

  1. To dodge the double layers, you must move (twice) to the side immediately after you hear the double beep sound queue.
  2. The charged lasers begin anti-clockwise and will move in your direction, a single jump will dodge this attack.
  3. The melee attack starts as the boss stands on its hind legs just before slamming its front down, so you must quickly boost diagonally forward to end up behind the boss and stagger him from behind.

The second phase is critical as Sea Spider’s energy falls below 50%, and it starts flying in the air. You must stay airborne and maintain enough boost energy to quickly boost when needed. Maintain your distance while attacking it in the air.

Best Build to Defeat Sea Spider

To defeat Sea Spider in Armored Core 6, I will use a heavy build like a tank. You will get many items by playing missions before you face the Sea Spider boss in AC6. But some must be purchased, and you should have a budget of around 1.4 million COAMs.
