A mech showdown in Armored Core 6

The battles in Armored Core 6 are half-won in your garage, where you’ll spend countless hours tinkering with your mech. Upgrades here will require materials like OST chips, so here’s everything you need to know about OST chips in Armored Core 6. 

Unlike most FromSoftware games, toppling a foe in Armored Core 6 takes more than just being a combat grunt, as customization has always been the core of the mech series. Even though you can crack metal skulls wide open with mechanics like stagger, you’ll eventually be torn apart by mean mechs if you refuse to craft new builds. 

Fortunately, you have a lot at your disposal to build in Armored Core 6 and can swap a lot of parts, like the head or core, and you can even buy yourself a new pair of powerful legs. You will need them if you’re to survive the game’s grueling campaign.

One such important resource is OST Chips. So, here’s all you need to know about OST chips in Armored Core VI: Fires of Rubicon.

What are OST Chips in Armored Core 6?

OST Chips are essentially a form of currency that’ll let you tune your mech in Armored Core 6 with new abilities, more damage, or armor. They can be used in the OS tuning section of your Garage and it will cost upwards of one OST Chip per upgrade.

All of the new abilities will unlock new gameplay mechanics, and will be slotted into the Expansion section on the Assembly menu.

OST Chips in Armored Core 6 can be obtained by simply playing Arena Mode. The Arena Mode is unlocked once you’ve completed a certain number of missions in Chapter 1 itself.
