Most boss fights in Armored Core 6 have a few small tricks to beating them, but offer the flexibility to use whatever AC build you want. There are some exceptions though, including the Ice Worm boss fight, which comes during the Destroy the Ice Worm mission in Chapter 3. This is the final mission of this chapter and if you don’t come into this fight with the right weapons setup, you will fail the mission. Here’s everything you need to know about beating the Ice Worm boss fight in Armored Core 6.
How to beat the Ice Worm
For this fight, you will need to have the shoulder weapon VE-60SNA Stun Needle Launcher, which is automatically unlocked by completing the prior mission. This weapon is necessary for stunning the Ice Worm, so you have to have it equipped. For the rest of your weapon slots, you will want to focus on high damage weapons, like grenade launchers or missile launchers. The reason for this is there is basically a damage check that you have to pass, otherwise you automatically fail the mission. Don’t worry though, you won’t need to fight any smaller enemies during this mission, as you will have some companions that will take care of that.
The mission structure is simple, you need to take down the Ice Worm’s shield by shooting it in the face with the Stun Needle Launcher. The worm moves a ton and you need to hit in the face–the game tells you the head, but it needs to be the face straight on. Just wait for the Ice Worm to stop moving and shoot. The Stun Needle takes a few moments to fire after activating it, so you need to lead the shot slightly.
