ARC Raiders: Sentinel ARC Enemy Guide

What to know

• Sentinels are medium unarmored turret ARC enemies found outdoors, usually on high ledges or rooftops.
• They attack with a powerful sniper-like heavy ammo shot after locking on with converging orange lasers.
• Aim for their vulnerable yellow canister to deal extra damage.
• Use cover to avoid their shots, and keep moving or dodge roll to evade damage.

Sentinels in Arc Raiders are a challenging enemy for ranged combat, often spawn high above on buildings or ledges. They stand out as threatening due to their powerful, slow-firing sniper shot preceded by visible laser targeting, giving you a clear warning to seek cover. Unlike indoor enemies like the Tick, Sentinels are commonly found outside overseeing open areas. This guide covers its locations, loot drops, combat behavior, and how to handle it efficiently.

ARC Raiders Sentinel: Quick overview

ARC Enemy Sentinel locations

Sentinels are stationary turrets found outdoors on rooftops, ledges, and other high spots overlooking key areas. They appear on maps like Dam Battlegrounds, Buried City, Blue Gate, and Acerra Spaceport—often near control towers, plazas, or checkpoints. You can spot them easily by their swiveling arm and yellow weak canister.

They use a visible laser to lock on before firing powerful shots, so use cover and move carefully when approaching. Sentinels often guard high-loot zones, and nearby ARC husks may drop Sentinel Firing Cores when destroyed.

How to fight the Sentinel in ARC Raiders

Before entering open areas, scan rooftops, ledges, and other high ground for stationary Sentinel turrets. Their silhouette is distinctive, and they guard these vantage points overlooking key outdoor spaces.

Once targeted, the Sentinel’s lasers lock on to you before firing. Use nearby cover to break line of sight immediately when the lasers lock on, or dodge roll and strafe to evade the shot.

Aim your shots at the Sentinel’s yellow canister located on its swiveling arm for increased damage. Use medium to heavy ammo weapons to maximize efficiency and reduce the fight duration.

Upon destruction, Sentinels drop valuable loot including the Sentinel Firing Core, Advanced ARC Powercell, and Heavy Ammo.

ARC Enemy Sentinel combat tips

• Always seek solid cover when you see the Sentinel's orange targeting lasers converging; this is your warning before a heavy sniper shot.
• Use dodge rolls, sliding, or quick movement to avoid the slow but powerful heavy ammo shots from the Sentinel turret.
• Focus your fire on the yellow vulnerable canister on its swiveling arm to deal extra damage and kill it faster.
• Prioritize high-damage or sniper-type weapons since Sentinels are stationary and slow to react.
