The fastest way to farm money in Armored Core 6 is to replay Destroy the Tester AC with a high-stagger close-range build. It pays 95,000 COAM, takes roughly 90 seconds to three minutes once mastered, and requires no late-game equipment. For larger individual payouts, replay Attack the Dam Complex, which pays about 270,000 COAM, or use Infiltrate Grid 086 for a reliable mid-game route. Open Replay Mission from the Sortie menu, finish quickly, and avoid unnecessary repairs, ammunition use, and optional detours.
Armored Core 6 does not use a traditional gold system. COAM is the currency used for weapons, frames, generators, boosters, and expansions. You can also sell owned parts for their full purchase value, so farming is mainly important when you want to buy and test several builds without waiting for the campaign to unlock more missions.
Best Early COAM Farm: Destroy the Tester AC
Destroy the Tester AC is the best repeatable money mission for a new save. It unlocks in Chapter 1, has a single primary target, and places the Tester AC in an open arena rather than a long level filled with mandatory encounters. Its listed reward is 95,000 COAM, and a clean clear is usually much faster than replaying a mission with multiple objectives.
Step-by-step route
- Open Sortie > Replay Mission and select Destroy the Tester AC.
- Use the starting launch sequence to move directly toward the marked Tester AC instead of exploring the surrounding terrain.
- Stay at close range and fire both shotguns together to fill the enemy’s Impact gauge.
- When the stagger bar turns yellow and the target becomes staggered, use a direct-hit punish such as the Pile Bunker’s PB-033M Ashmead charged attack.
- Repeat the stagger cycle until the Tester AC is destroyed, then accept the results screen and immediately launch the replay again.
The Tester AC has enough mobility to punish slow, ground-bound builds, but its attacks are easy to read in the arena. Boost diagonally rather than retreating in a straight line, and use an Assault Boost only when closing distance or crossing the arena. If the Pile Bunker feels inconsistent, replace it with SONGBIRDS shoulder grenade launchers for a safer stagger punish.
Fast Farming Builds for Repeat Missions
Build around Impact damage, short engagements, and low repair costs. A simple early-game setup uses dual WR-077 HARRIS linear rifles or dual shotguns, with SONGBIRDS on the shoulders. Once unlocked, dual SG-027 ZIMMERMAN shotguns are one of the fastest options for farming because two point-blank volleys build stagger rapidly. The DF-GN-08 SAN-TAI generator provides strong EN capacity for aggressive movement, while the BST-G2/P06SPD booster supports quick ground repositioning.
For a close-range Zimmermans build, prioritize a medium biped frame that can carry both shotguns and your preferred shoulder weapons without exceeding the load limit. Put the OS Tuning points from Arena rewards into Direct Hit Modifier and Weapon Bay if you want to swap a shoulder weapon for a melee weapon. Weapon Bay lets the shoulder slot carry a second firearm, making a Zimmerman-to-Pile-Bunker rotation possible.
The basic rotation is simple: fire both Zimmermans, Assault Boost toward the staggered target, switch to PB-033M Ashmead, and use the charged attack during the stagger window. Against normal MTs, one volley is often enough. The goal is not maximum style or an S rank; it is the highest reliable net COAM per minute. For more build-focused optimization, compare this approach with Steamoz’s solo class build advice, even though the games use very different combat systems.
Best Mid-Game Alternative: Attack the Dam Complex
Attack the Dam Complex is the better choice when you want a larger payout per completion. The mission lists approximately 270,000 COAM and becomes particularly efficient after you are comfortable destroying the initial MT groups and the two main AC encounters. It takes longer than Tester AC, but one clean run is worth nearly three early farms.
Efficient Dam Complex route
- Move through the first objective area using Assault Boost, destroying only enemies blocking the mission route.
- At the first combat section, target the heavier MTs before they can surround your AC. Do not waste shoulder ammunition on light targets.
- When the mission directs you to the dam objective, stay mobile and use vertical movement to avoid concentrated fire.
- Against the AC encounter, use the same Impact-first rotation: dual shotguns, then a melee or SONGBIRDS punish after stagger.
- Finish the objective and extract without detouring for unneeded enemies or collectibles.
Use this mission when your Tester AC clear is slower than about two and a half minutes or when you need a break from the same arena. A heavy reverse-joint or biped build can work well here, but watch your ammunition. Missing grenade shots and firing at distant MTs can reduce the final reward through resupply and ammunition deductions.
Grid 086 and Other Useful Mission Replays
Infiltrate Grid 086 is a dependable mid-game farm because its industrial layout contains predictable enemy groups and a valuable final encounter. It is not as fast as Tester AC, but it gives more combat variety while still paying a solid mission reward. Use the shortcut routes through the central structure, ignore optional enemies that do not guard the objective, and save your highest-damage weapons for the final AC battle.
Destroy the Weaponized Mining Ship is another worthwhile replay once unlocked. Its approximately 250,000 COAM payout makes it attractive if your build can destroy the mining ship quickly. Fly between the marked weak points rather than hovering directly in front of the vessel, then focus on exposed targets after each attack cycle. A fast reverse-joint AC or a lightweight biped can reduce travel time considerably.
Later missions can provide higher single-run rewards, but they are not automatically better farms. Long missions with bosses, mandatory travel, and expensive ammunition can produce less COAM per minute than Tester AC. Measure the complete run from the replay loading screen to the results screen, not just the number displayed in the briefing.
How to Maximize Net COAM Per Run
The mission result is reduced by repair and ammunition expenses, so the displayed reward is not always your actual profit. Use the lightest effective loadout, avoid taking direct hits, and do not fire explosive weapons at targets that can be killed with a rifle or shotgun. If your AC finishes with heavy damage, a slightly slower but safer build may be the better farm.
Never buy a replacement part just to test it during a farming run. From the Garage, selling a weapon or frame returns its full purchase price, which means you can liquidate unused parts without losing COAM. Keep one reliable farming build saved, sell experimental equipment after testing, and buy it again when you are ready to use it.
OS Tuning also matters. Damage Control reduces incoming damage, Repair Kits increase the value of each repair, and Access Speed shortens important interactions. None directly increases COAM, but Damage Control can reduce deductions during longer replays. For PC performance, stable frame pacing helps with stagger timing; Steamoz’s Steam Deck settings guide explains the same kind of performance-first approach for portable play.
When to Stop Farming and Return to the Campaign
Farm only until you can purchase the specific weapon, frame, generator, or FCS needed for your next build. Armored Core 6 unlocks more equipment through campaign progression, Arena completion, Loghunts, and New Game Plus, so excessive early grinding is rarely necessary. After buying the key parts, return to the story and unlock stronger options that make later replays faster.
For most players, the efficient order is Destroy the Tester AC early, switch to Attack the Dam Complex after its payout becomes available, and use Grid 086 or Destroy the Weaponized Mining Ship when you want variety. The official Armored Core VI Steam page lists the game’s core features, while the official Armored Core website provides current game information. For developer updates, check FromSoftware’s official site.
If you want a broader guide library after optimizing your AC, Steamoz also covers performance settings for demanding games and Steam Deck game recommendations. In Armored Core 6 itself, however, the rule remains straightforward: choose the shortest mission you can clear consistently, protect your AP, and repeat it through Replay Mission.
