Arc Raiders: Turnabout Quest is one of the most challenging and rewarding missions in the Arc Raiders universe. Combining combat, environmental puzzles, platforming, and strategic boss encounters, it tests both reflexes and intellect. Completing this quest not only advances the story but also grants high-tier loot, including Arc-Infused Weapon Cores, rare crafting components, and legendary cosmetic ARC Raiders Items. This guide walks you through every phase of the quest, ensuring a smoother experience and maximizing rewards.

 

Quest Overview

The Turnabout Quest begins at the Sealed Gate of Echoes, a towering crystalline structure radiating unstable Arc energy. Your mission is to investigate the anomaly and stop the corruption threatening the surrounding world. To tackle this quest effectively, players should ideally be level 45 or above with a gear score of at least 380. This ensures you have sufficient damage output and survivability for the challenging enemies and environmental hazards.

 

Key rewards include Arc-Infused Weapon Cores, rare crafting materials, and cosmetic items like the Echo Stalker Cloak. The quest's structure blends puzzle-solving, combat encounters, and platforming sequences, requiring players to be adaptable and attentive.

 

Phase 1: Arrival at the Echo Gate

Upon entering the quest, you first encounter the Echo Gate interface. This area features four Resonance Nodes arranged in a diamond pattern, each with rotating symbols. To proceed, you must match the nodes to the glyph pattern displayed on the central Arc console. Accuracy is essential, as even a single mismatched symbol prevents activation.

 

Once the nodes are aligned, the gate activates with a surge of Arc energy, opening a path deeper into the Shattered Vault. However, almost immediately, you face your first combat challenge: an ambush by Arc-corrupted Sentinels. These enemies teleport unpredictably and have high mobility. Prioritize larger Sentinel Brutes, which can stagger allies. Using tracking grenades and area-of-effect abilities helps reveal cloaked enemies, while maintaining lateral movement avoids teleportation strikes. Clearing this ambush allows you to advance toward the next area.

 

Phase 2: Navigating the Shattered Vault

The Shattered Vault is a vast, ruined cathedral filled with crystalline structures and Arc energy. Floating platforms and rune-inscribed crystals create a visually stunning, but dangerous, environment. Your first task here is to restore three Arc Foci by solving light-beam redirection puzzles.

 

The first focus requires directing a beam through two crystal prisms to illuminate three runes. Each prism rotates, and the beam must pass through them in the correct color order. The second focus involves a mirror and two side crystals, where the mirror must face east, and the beams from the side crystals redirected accurately. The third focus is the most challenging, requiring precise timing to pass a beam through spinning lenses. Activating the focus at the wrong time resets the puzzle, so patience is crucial.

 

After restoring all three Foci, a bridge across the Crystalline Chasm becomes accessible. The platforming here demands careful timing, as platforms fade in and out in a cycle. Dashing between platforms while using the Arc Shield to mitigate fall damage is recommended. Successfully crossing this area brings you to the Arc Gate leading to the Anomaly Chamber.

 

Phase 3: The Arc Anomaly

The Arc Anomaly is a warped, unstable arena populated with Arc Phantoms and environmental hazards. Your objectives are to defeat all Phantoms and stabilize the Arc Core.

 

Arc Phantoms teleport unpredictably from portal flares. Destroying the flares prevents reinforcements from entering the battlefield. Phantoms are weak to EMP rounds and Pulse Blade attacks, so players should adjust their loadouts accordingly. After clearing the enemies, you must stabilize the Arc Core through a multi-step sequence: aligning stabilization beams, activating safety conduits, and overcharging the core. Each step triggers waves of environmental hazards, so maintaining high mobility is essential. Once the core is stabilized, the final boss, Vexar Prime, arrives.

 

Phase 4: Boss Encounter - Vexar Prime

Vexar Prime is a powerful corrupted Arc construct with three distinct combat phases. Each phase requires awareness, strategy, and adaptability.

 

Phase A: Energy Assault

In the first phase, Vexar hovers above the arena, firing Arc Orbs in spread patterns. Lateral movement is essential to avoid damage. Destroying surrounding light beacons reduces the number of incoming orbs, making the fight more manageable. Phase A ends when Vexar's health drops below 70%.

 

Phase B: Ground Siege

Vexar transitions to the Ground Siege phase, slamming the floor to spawn Arc Sentinels and leaving Arc Spores on the ground. The spores detonate if you remain in one spot, and sentinels heal Vexar if left alive. The recommended strategy is to prioritize the sentinels using area-of-effect attacks while continuously moving to avoid spores and slam attacks. Proper positioning is critical to surviving this stage.

 

Phase C: Core Rupture

The final phase exposes Vexar's core, unleashing massive shockwaves, a vortex that pulls players inward, and tracking laser beams. The Arc Shield ability is invaluable here for absorbing shockwave damage. To avoid laser lock-ons, players should move unpredictably, using dashes to escape the vortex. Timing and positioning are crucial for avoiding fatal damage during this phase. Once Vexar's health reaches zero, the boss explodes, signaling the successful completion of the quest.

 

Combat Tips and Recommended Loadouts

To maximize efficiency, equip weapons suited to both single-target and area-of-effect damage. Arc Rifles are ideal for precise, high-damage shots, while Pulse Launchers handle multiple enemies and shields. EMP Blasters are effective against Arc constructs, particularly during boss fights.

 

Armor mods are equally important. Overcharge Resilience, Shield Regeneration Acceleration, and Arc Damage Boost provide survivability and offensive enhancement. Maintaining distance in boss fights, using Arc Shields in hazard zones, and conserving consumables like health packs and overcharge energy are all critical strategies. You can buy ARC Raiders Materials to craft them.

 

Puzzle Solutions and Environmental Awareness

Success in Turnabout Quest requires careful observation of environmental cues. The Resonance Node puzzle at the Echo Gate demands precise symbol alignment. Light-beam redirection for Arc Foci requires attention to prism rotations, mirror orientation, and timing with spinning lenses. Stabilizing the Arc Core involves aligning beams, activating conduits, and overcharging at the right moments. Failing these puzzles can force repeated attempts, so patience is key.

 

Secrets and Hidden Rewards

Hidden throughout the Shattered Vault are Echo Fragments, which unlock the Legendary Cosmetic Cache and the Echo Stalker Cloak when all are collected. Fragments are often located in hard-to-reach areas, such as behind ambush zones, on floating platforms near the Arc Foci, and under collapsed arches. Exploring thoroughly ensures that you collect all fragments and obtain maximum rewards.

 

Common Mistakes to Avoid

Players often make several mistakes during Turnabout Quest. Rushing through platforming sequences without timing can lead to falls and unnecessary damage. Ignoring light beacons during the Vexar fight increases orb spam. Using the wrong weapons on certain enemies, or attempting to divide attention between Vexar and minions, can result in avoidable deaths. Prioritization, patience, and methodical execution are essential for a smooth completion.

 

Loot and Farming Strategies

After completing the quest, players can re-engage Vexar Prime for higher-tier loot drops. Increasing the quest's difficulty improves the chance of obtaining rare Arc-Infused Weapon Cores. Completing all combat phases without dying grants additional experience points, making repeated runs a valuable way to level and gather resources. Exploring every nook of the Shattered Vault ensures access to hidden items and maximizes rewards.

 

Conclusion

Arc Raiders: Turnabout Quest is a standout mission that challenges players with its combination of puzzles, platforming, and combat. Mastery of this quest requires careful observation, precise execution, and strategic planning. By understanding each phase, equipping the appropriate loadout, and exploring thoroughly, players can overcome the Turnabout Quest, earn valuable rewards, and gain skills that will serve them in subsequent, more demanding content. Its complexity and variety make it a highlight of Arc Raiders, offering a memorable and rewarding experience for all who take on the challenge.
