A complete guide to Armored Core 6 OST Chips: Master Arena missions and optimize your mech with advanced strategies.
Understanding OST Chips: The Core Upgrade System
OST Chips serve as the fundamental building blocks for enhancing your Armored Core’s performance in Armored Core 6. Unlike temporary boosts or consumable items, these chips provide permanent, stat-based improvements that directly shape your mech’s capabilities throughout the entire campaign and beyond.
Think of OST Chips as the skill points of Armored Core 6. They are a finite resource you earn through challenging combat scenarios, used to unlock powerful enhancements across several key categories.
Managing a mech effectively demands balancing multiple combat vectors simultaneously. You must fine-tune your boost speed for evasion without sacrificing stability, equip weaponry capable of breaking an enemy’s posture for critical hits, and reinforce your armor to survive punishing boss encounters. OST Chips give you the direct control to address these needs.
The beauty of the system lies in its flexibility. Whether you favor a lightweight, high-mobility skirmisher or a heavily armored tank build, OST Chips allow you to invest in the stats that support your chosen playstyle, making your mech truly your own.
OST Chips unlock upgrades in distinct categories: Offensive (new melee combos, weapon bay efficiency), Defensive (AP increases, damage mitigation), Mobility (boost speed, quick-turn capabilities), and Support (repair kit effectiveness, scan duration).
The cost structure is tiered. Basic upgrades, like a minor increase to your core Armor Points (AP), may cost a single chip. More transformative abilities, such as acquiring a powerful new Assault Armor explosion or significantly enhancing your generator output, can require three or more chips, demanding careful long-term planning.
Acquiring OST Chips: The Arena Grind
Your sole method for obtaining OST Chips is to prove your prowess in the Arena, a dedicated combat simulator accessed from your garage menu.
The Arena presents a series of ranked matches against AI-controlled Armored Cores, often based on enemy pilots you encounter in the main story. Each victory awards you a set number of OST Chips and progresses you to the next, more difficult opponent. This is not a side activity but a core progression system.
Pro Tip: Don’t wait until you’re stuck in the story to tackle the Arena. Revisit it after every main mission unlock, as new opponents frequently appear. Early and consistent Arena clears provide a steady chip income to power up for tougher story bosses.
For veterans of the series, this format will feel familiar. The Arena has long been a staple for testing builds and earning rewards. In Armored Core 6, it’s seamlessly integrated into the progression loop, serving as the perfect training ground to experiment with new chip-funded upgrades before a high-stakes mission.
Common Mistake: Attempting to brute-force Arena matches with an unoptimized loadout. If you’re struggling against a particular AI, leave the Arena, use your chips to counter their strengths (e.g., boost speed against a slow, heavy hitter), then retry. The Arena is a puzzle to be solved with upgrades.

Advanced Optimization and Strategic Spending
With a finite chip supply, strategic investment is crucial. Your early priorities should address fundamental survivability and mobility. Upgrades to your core AP (health) and your booster efficiency are universally valuable, regardless of your eventual build. They provide the safety net to learn enemy patterns and complete missions.
Optimization Tip for Advanced Players: Once fundamentals are covered, align your chip spending with your weapon choices. If you rely on melee, invest in chips that reduce melee cooldown or increase lunge distance. For missile boats, prioritize lock-on speed and missile reload. Specialization yields greater returns than generalization.
A major pitfall is spreading your chips across too many weapon types early on. It’s better to have one devastating weapon system than three mediocre ones. Focus your offensive chips to maximize the effectiveness of your favorite primary weapon.
Endgame Consideration: Before starting New Game+, aim to have cleared all available Arena ranks. The chips earned will give you a significant power baseline for the increased difficulty. Some of the most expensive and powerful upgrades are designed with the replayability and challenge of subsequent playthroughs in mind.
