ARC Raiders Augments and Shields Guide: Best Builds by Role

Augments are the foundation of every ARC Raiders build: they set your carry limit, inventory layout, Safe Pockets, utility slots, and—most importantly—which Shield tiers you can equip. For the current live game, the strongest all-purpose choices are Looting Mk. 3 (Survivor) for high-capacity solo or squad raids, Tactical Mk. 3 (Defensive) for sustained fighting with a Heavy Shield, and Combat Mk. 3 (Flanking) for mobile PvP. Do not choose a Shield first and try to force it into a build; choose the Augment that supports your job, then equip the Shield whose protection and movement penalty fit your route.

ARC Raiders has received important equipment changes since the older 1.39.0 update. The October 8 Frozen Trail 2.0 update reduced the Heavy Shield movement penalty from 15% to 10% and improved its durability, while Live Update 2.3.0 on October 27 increased its base charge from 80 to 90. These live changes make Heavy Shields more competitive without removing the mobility advantage of lighter setups.

How Augments and Shields Work

An Augment is more than a backpack. It defines how much total weight you can carry, how many slots are available for loot and combat supplies, which protected Safe Pocket slots you have, and whether you can equip a Light, Medium, or Heavy Shield. You cannot replace an Augment once you are Topside, so solve compatibility and inventory problems before launching.

Shields reduce incoming damage while they have both charge and durability. They are not simply extra health. A higher-tier Shield gives more charge and better damage mitigation, but Medium and Heavy Shields also reduce movement speed. That trade-off matters most when you need to rotate through exposed terrain, escape a third party, or reach an extraction before another squad closes in.

Key rule: every Augment supports a Light Shield, but only selected models accept Medium or Heavy Shields. If a Medium Shield will not equip, your current Augment is the problem—not the Shield itself.

Best ARC Raiders Augments by Role

The strongest Augment depends on what you intend to accomplish Topside. Carrying capacity favors loot runs, integrated recovery tools favor defensive fights, and fast sidearm handling matters most when you can actually create flanking angles. Compare the role and limitation together before committing to a frame.

A finished Augment and its crafting Blueprint are different items. A finished frame can be equipped for a raid, while the Blueprint unlocks the corresponding recipe when you meet its crafting requirements. The ARC Raiders Augment catalog lists the individual Mk. 1, Mk. 2, and named Mk. 3 variants for comparing the exact frame you need.

Best Solo Build: Looting Mk. 3 (Survivor) + Medium Shield

Looting Mk. 3 (Survivor) is the most complete Augment for players whose priority is getting out alive with enough loot to make each raid matter. It supports Light and Medium Shields, has an 80 weight limit, five Quick Use slots, three Safe Pockets, and an extra deployable utility slot. Its unique effect restores downed health while you remain stationary, up to 75% of your maximum downed health. This recovery does not revive you by itself.

That passive is not an excuse to crawl into an open lane and hope for a rescue. Its real value is buying your squad more time to clear pressure, rotate back, or force an enemy to commit deeper than they want. For solos, it offers a little more room for an unlikely recovery window or a safer negotiation after being downed.

• Primary weapon: Kettle, Ferro, or Anvil based on budget and intended ARC pressure.
• Secondary: A pistol or Hand Cannon if you expect close-range interior fighting.
• Shield: Medium Shield. It is the practical balance between survivability and movement.
• Quick Use: healing, Shield Rechargers, one mobility item, and an emergency escape utility.
• Deployables: reserve the extra slot for a barricade, zipline, mine, or situational tool you find Topside.

Use Survivor when you are running long loot loops, carrying quest items, moving through mixed PvE and PvP zones, or playing with a squad that can realistically revive you. If you are deliberately hunting boss-tier ARC targets, a Heavy-Shield build offers more direct protection.

Best Secure-Loot Build: Looting Mk. 3 (Safekeeper) + Heavy Shield

Looting Mk. 3 (Safekeeper) is the specialist choice for raids where one protected item is worth more than the rest of your inventory. Its defining feature is a Safe Pocket that accepts any item, allowing you to protect valuables that would not normally fit in a standard protected slot. It also supports every Shield tier, including Heavy.

This is the best Augment for blueprint hunting, rare boss materials, valuable weapons you need to secure, and objectives that create a strong incentive to leave immediately after success. Its 65 weight limit is respectable, but it does not match Survivor for bulk scavenging. Treat Safekeeper as a protection build, not a “fill every slot” build.

• Place the irreplaceable item in the special Safe Pocket as soon as you acquire it.
• Use a Heavy Shield when you expect a forced exit through exposed ground or a high-pressure extraction.
• Do not stay in the raid merely because you still have open inventory slots; this Augment is strongest when it protects the one find that matters most.
• Bring enough Shield recovery to sustain the Heavy Shield. Its reduced 10% movement penalty still makes some late disengages harder than with Medium.

Before risking rare components, review the ARC Raiders keep, sell, and stash guide so valuable crafting and progression items do not disappear into a bad post-raid cleanup decision.

If your objective is an Augment recipe rather than a finished frame, distinguish the item you extract from the craft you can eventually make. The ARC Raiders Blueprint catalog separates recipe unlocks from finished equipment; finding or protecting a Blueprint does not automatically provide the crafted Augment.

Best Defensive Squad Build: Tactical Mk. 3 (Defensive) + Heavy Shield

Tactical Mk. 3 (Defensive) is the premier hold-the-line Augment. It supports Heavy Shields, includes an Integrated Shield Recharger, and lets you use Shield Rechargers while running. That combination is especially valuable in extended ARC encounters, noisy objective areas, and squad fights where you must survive a retreat rather than win every trade immediately.

This is the build for the player who anchors a revive, controls the safest angle, carries the squad’s utility, or remains behind to cover an extraction. The Heavy Shield’s current 10% movement penalty is real, even after the reduction from 15%, so you still need to route more carefully than a Medium-Shield player. Start every engagement with a retreat lane in mind; do not make the Heavy Shield solve a positioning problem you created.

• Primary weapon: Bettina, Anvil, or Ferro for reliable pressure against armored ARC targets.
• Secondary: A close-range option for indoor pushes and defensive holds.
• Shield: Heavy Shield.
• Utility priority: Shield Rechargers first, healing second, then a defensive deployable or smoke tool.
• Squad job: hold a lane, cover revives, absorb the first response to an ARC pull, and call the reset when the fight becomes a third-party magnet.

For weapon choices that fit this role, see the ARC Raiders weapons and gadgets guide. A durable build still fails if it lacks a weapon that can handle the target you chose to fight.

Compare normal and stronger Shield Rechargers alongside your healing and escape tools before assigning Quick Use slots. The ARC Raiders Quick Use item list distinguishes Shield recovery from healing, combat, and mobility supplies; carrying the wrong mix can waste the Defensive frame’s main advantage.

Best Aggressive PvP Build: Combat Mk. 3 (Flanking) + Medium Shield

Combat Mk. 3 (Flanking) is the best Augment for players who win fights by changing angles, breaking contact, and rapidly swapping to a sidearm rather than by standing in a damage trade. It supports Light and Medium Shields, has a 60 weight limit, two Safe Pockets, five Quick Use slots, and three deployable utility slots. Its passive makes stowed or unequipped Pistols and Hand Cannons 33% faster to equip.

The perk only matters if your loadout is designed around it. Pair a primary weapon for your opening range with a pistol or Hand Cannon that can finish a damaged opponent inside tight cover. The three deployable slots are equally important: they let you bring tools for entry, denial, and escape instead of spending your entire kit on raw healing.

• Primary weapon: Tempest, Kettle, or another controllable PvP primary.
• Secondary: Pistol or Hand Cannon; do not waste the swap-speed perk on an unused sidearm.
• Shield: Medium Shield for survivability without the Heavy Shield’s greater rotational cost.
• Utilities: one movement tool, one denial tool, and one extraction or repositioning tool.
• Fight rule: use your first angle to gather information; use the second angle to deal decisive damage.

Flanking is not the best build for standing in front of a boss or holding an exposed extraction. It is for initiating from a strong position, forcing enemy attention to split, and leaving before the opposing squad can turn your push into a slow trade. The ARC Raiders PvP fundamentals guide covers the sound, positioning, and disengage rules that make this playstyle work.

Best Sustained Combat Build: Combat Mk. 3 (Aggressive) + Heavy Shield

Combat Mk. 3 (Aggressive) supports all Shield tiers and restores two health every five seconds, but the effect pauses for 30 seconds after you take damage. That means its health regeneration is a between-fights sustain tool, not an in-fight healing substitute. It has a 65 weight limit and two grenade slots, making it a strong option for players who expect repeated fights and have the discipline to reset after each engagement.

Choose this over Tactical Defensive when you want heavier personal fighting capacity and can carry your own healing and Shield recovery. Choose Defensive instead when the ability to recharge a Shield while moving and the integrated tool are more likely to decide the raid.

Combat Mk. 2 is the cheaper version of this concept. It supports Heavy Shields and provides one health every five seconds, also pausing for 30 seconds after damage, making it an excellent progression Augment when you do not want to risk a Mk. 3 frame.

Best Support Build: Tactical Mk. 3 (Healing) or Revival

Support has two distinct approaches, and the correct Augment depends on what your squad lacks. Tactical Mk. 3 (Healing) also received a significant change in Patch 1.29.0: Cloud of Renewal became an area-of-effect heal, with 45 healing and a 45-second cooldown.

• Tactical Mk. 3 (Healing): supports Medium Shields, carries three healing-item slots and three grenade slots, and releases Cloud of Renewal when you are revived from a downed state. The 45-point area heal can benefit nearby teammates, but it can also heal enemies caught in the effect. Choose it for aggressive squads where revives happen frequently and teammates can capitalize on the cloud without helping the opposing squad.
• Tactical Mk. 3 (Revival): includes an Integrated Defibrillator and passive health regeneration, but supports only Light Shields. Choose it for a designated medic who prioritizes revives, stays behind cover, and avoids becoming the first target.
• Tactical Mk. 3 (Smoke): supports Medium Shields and deploys smoke after a Shield break. It is a useful alternative for squads built around recovery, exits, and crossing exposed lanes.

Do not confuse an integrated tool with a freely selectable gadget. The Defensive Augment’s Shield Recharger and Revival Augment’s Defibrillator are built into those specific Augments; you only gain them by equipping the corresponding frame. Cloud of Renewal is a healing effect, not an additional revive ability.

Every Augment Family Explained

ARC Raiders groups its regular Augments into Combat, Looting, and Tactical families. Each offers different inventory layouts, Shield compatibility, and special abilities. The Free Loadout also has its own basic Light-Shield Augment, but it does not replace a specialized frame for a planned raid.

Combat Augments

Combat frames prioritize Shield access, personal sustain, grenade capacity, and fighting weight limits.

• Combat Mk. 1: entry-level Medium Shield access. Use it when you need a simple combat-ready kit without risking higher-tier gear.
• Combat Mk. 2: first affordable Heavy Shield option; slow passive health regeneration improves recovery between encounters.
• Combat Mk. 3 (Aggressive): stronger sustain and more grenade capacity for extended combat.
• Combat Mk. 3 (Flanking): Medium-Shield mobile-combat frame with fast sidearm swaps and extra deployable slots.

Looting Augments

Looting frames emphasize capacity, Safe Pockets, and getting out with progress rather than winning every fight.

• Looting Mk. 1: a reliable early-game Light-Shield scavenging frame.
• Looting Mk. 2: adds greater capacity, more Safe Pockets, deployable slots, and automatic Tick removal.
• Looting Mk. 3 (Cautious): Light Shield only, but excellent capacity, Integrated Binoculars, and a weak emergency Adrenaline Shot when your Shield breaks.
• Looting Mk. 3 (Safekeeper): the item-protection specialist with Heavy Shield access.
• Looting Mk. 3 (Survivor): the best broad looting frame for volume, Safe Pockets, and downed survival.

Tactical Augments

Tactical frames lean into Quick Use capacity, special recovery effects, and integrated utility.

• Tactical Mk. 1: basic Medium Shield access with five Quick Use slots.
• Tactical Mk. 2: deploys a small smoke grenade when your Shield breaks; useful while learning resets and escape timing.
• Tactical Mk. 3 (Defensive): the Heavy-Shield specialist for sustained defense.
• Tactical Mk. 3 (Healing): revive-response support with an area heal and extra healing and grenade capacity.
• Tactical Mk. 3 (Revival): dedicated revive utility at the cost of Medium and Heavy Shield access.
• Tactical Mk. 3 (Smoke): Medium-Shield support frame focused on automatic smoke cover after Shield break.

Shield Selection Rules That Prevent Bad Builds

Shield selection is a trade-off between protection and movement, not a simple ranking by tier. Use the following rules to match the current 40-, 70-, and 90-charge options to your actual raid plan.

1. Use Light Shield when speed, low risk, and cheap replacement cost matter more than prolonged fighting. It is the default choice for Free Loadouts and Light-Shield-only Augments.
2. Use Medium Shield for almost every mixed PvPvE raid. The 5% movement penalty is manageable, while the extra charge and mitigation give you more room to heal, reposition, or finish a fight.
3. Use Heavy Shield when your Augment supports it and your raid plan includes direct pressure: boss hunting, objective defense, squad anchoring, or expensive-item extraction. Its 90 charge and 10% movement penalty make it more flexible than before.
4. Do not wear Heavy Shield automatically for every fast, exposed loot loop unless you are protecting a specific high-value objective. You may survive the first exchange but still lose time on the later rotation.
5. Carry Shield recovery that matches your plan. A Heavy Shield without enough recharge capacity is just extra weight after the first hard engagement.

The most common mistake is treating Shield tier as a universal power ranking. Heavy Shield offers the greatest protection in a committed fight, but Medium Shield is usually better for a mobile solo build, and Light Shield is often correct when the purpose of the raid is to scout, loot, or recover economically.

Role Builds for Common Raid Plans

These three loadouts turn the general recommendations into practical raid plans. The best combination depends on whether you are recovering resources, deliberately drawing ARC pressure, or coordinating a three-person push.

Budget Recovery Run

Augment: Looting Mk. 1 or Mk. 2
Shield: Light Shield
Weapons: replaceable primary plus a cheap sidearm
Supplies: healing, one Shield Recharger, one escape or traversal option
Goal: extract with materials, not chase gunfire.

Use this after an expensive loss, when you need crafting supplies, or when you are learning a map condition. Take fights only when they block an objective or offer a clean advantage. A low-cost kit becomes profitable through consistent extracts, not surprise heroics.

High-Risk Boss or Elite ARC Hunt

Augment: Tactical Mk. 3 (Defensive) or Combat Mk. 3 (Aggressive)
Shield: Heavy Shield
Weapons: an ARC-capable primary with sufficient ammunition plus a close-range backup
Supplies: multiple Shield Rechargers, healing, area denial, and a planned retreat utility
Goal: secure priority drops, then extract before the encounter attracts more Raiders.

Heavy-Shield boss kits work because they absorb more pressure while you manage the target, adds, and incoming players. The increased 90 charge helps, but it does not replace cover or a retreat route. These kits fail when a team tunnels the boss without reserving an escape lane. For target-specific preparation, use the ARC Raiders boss and elite guide.

Three-Person Push Squad

Frontliner: Tactical Mk. 3 (Defensive) + Heavy Shield
Flanker: Combat Mk. 3 (Flanking) + Medium Shield
Support/loot carrier: Looting Mk. 3 (Survivor) + Medium Shield

This composition gives the group a durable anchor, a player who can create off-angles, and a high-capacity Raider who can carry supplies and secure loot. The frontliner should not chase every down; the flanker should not be the first player to hold a revive; and the Survivor player should not take the first exposed entry. Roles matter because they prevent three players from bringing the same strength and sharing the same weakness.

The same equipment checks apply to any organized team, including players using ARC Raiders squad assistance: decide who handles revives, Shield recovery, and valuable loot before entering the raid. An agreed role matters more than giving everyone the heaviest available Shield.

Common Augment and Shield Mistakes

Most failed loadouts come from mismatched equipment or a passive ability that does not suit the fight. Check these problems before risking an expensive Augment.

• Equipping a Shield before confirming compatibility: inspect the Augment’s supported Shield tiers before buying or crafting a Medium or Heavy Shield.
• Using Heavy Shield as a default: its protection is excellent, but even the reduced 10% movement penalty can cost you time on fast routes that do not require Heavy protection.
• Ignoring weight limit: a powerful combat kit becomes unreliable when ammo, healing, loot, and utilities overload the frame.
• Overvaluing passive regeneration: Combat regeneration stops for 30 seconds after damage. It helps during quiet resets, not while you are being pushed.
• Misusing Safe Pockets: protect irreplaceable blueprints, objective items, rare components, or the single item that turns the raid into progression—not low-value filler.
• Forgetting that Augments cannot be swapped Topside: check your Shield, supplies, and intended role in the loadout screen before queueing.
• Running a specialist frame without its purpose: Flanking needs a sidearm plan, Safekeeper needs a high-value objective, and Defensive needs enough Shield recovery to exploit its advantages.

Final Build Recommendation

If you want one answer for most raids, run Looting Mk. 3 (Survivor) with a Medium Shield. It offers the best balance of carrying capacity, protected inventory, Quick Use flexibility, and survivability without accepting the extra movement cost of a Heavy Shield.

Move to Tactical Mk. 3 (Defensive) with a Heavy Shield when your squad is intentionally taking long fights, defending an objective, or hunting dangerous ARC targets. Choose Combat Mk. 3 (Flanking) with a Medium Shield when your value comes from fast angles, sidearm swaps, and deployable utility. And if the entire raid is about protecting a single rare item, Looting Mk. 3 (Safekeeper) is the correct investment.

Before committing expensive equipment, check the Augment’s Shield compatibility, your available weight, the utility slots you will actually use, and the route back to extraction. The Heavy Shield buffs make defensive setups stronger, but they do not make a specialized Augment equally effective in every situation.

FAQ

These answers clarify three mechanics that can affect an Augment choice even after you have selected the right Shield.

Does Looting Mk. 3 (Survivor) revive you automatically?
No. Its passive restores downed health while you remain stationary, up to 75% of maximum downed health. You still need a valid way to be revived; the passive only helps you survive longer while downed.

Can Tactical Mk. 3 (Healing) revive a downed teammate with Cloud of Renewal?
No. The cloud heals Raiders in its area after the Augment wearer is revived. An earlier issue that allowed it to revive downed Raiders was fixed in Live Update 1.33.0. It can also heal enemies within range.

Is a finished Mk. 3 Augment the same as its Blueprint?
No. A finished Augment is equipment for a loadout. A Blueprint teaches a crafting recipe, provided you have the necessary workshop progression and materials. Protecting one does not automatically give you the other.

Conclusion

Choose the Augment for the job, confirm Shield compatibility, and pack enough recovery for the fights you expect. Survivor with Medium remains the flexible default; Defensive with the buffed Heavy Shield is the stronger choice for committed pressure, while Flanking and Safekeeper reward specialized raid plans.
