ARC Raiders features many hidden loot sources, but Raider Caches are some of the most valuable—and risky—ones to find. This guide explains how Raider Caches work, how to locate them reliably, and where to search on each major map during the Uncovered Caches event.

What Is the Uncovered Caches Map Modifier?

Uncovered Caches is a special map modifier that changes how Raider Caches behave during a match:

• More Raider Caches spawn across the map
• Loot inside the caches is more valuable than usual
• Caches are partially exposed due to recent storms
• Exposed caches can explode if left untouched for too long

This modifier rewards players who move efficiently and know where to search, but it also punishes hesitation.

How to Find Raider Caches

Raider Caches are hidden underground, but they are designed to be detectable if you pay attention.

Audio Cues

• A low whirling sound, similar to a small motor
• A high-pitched ticking noise layered on top

If you hear both sounds close together, a cache is usually nearby.

Visual Markers

• Look for small red arrow-shaped signs
• These signs point directly toward the cache location
• The cache itself is usually buried just below the surface

Once you spot a marker, search the ground in the direction it indicates.

4. Blue Gate

Below are the main maps where Raider Caches can appear during the Uncovered Caches event. Exact spawn points vary, but these areas consistently produce results.

1. Dam Battlegrounds: Raider Cache Map Location

Dam Battlegrounds has uneven terrain and industrial ruins, making audio cues especially important.

Common cache areas include:

• Slopes near collapsed concrete structures
• Edges of the dam where debris has piled up
• Shallow dirt patches close to broken walkways

Sound travels well here, so stop moving briefly and listen.

For players who want to save time in ARC Raiders, some choose to get key progression items directly instead of relying only on cache luck. If you are looking for Arc Raiders blueprints for sale, SHANNENG is often used by players as a straightforward marketplace to find specific blueprints they are missing. It is usually treated as a practical option when farming locations like Dam Battlegrounds becomes repetitive or unpredictable, especially during limited-time map modifiers.

2. Buried City: Raider Cache Map Location

Buried City lives up to its name, with many caches hidden under sand and rubble.

Best places to check:

• Open plazas partially covered by sand
• Gaps between collapsed buildings
• Sunken streets where storm damage is visible

Visual markers are easier to spot here than audio cues due to ambient noise.

3. Acerra Spaceport: Raider Cache Map Location

Acerra Spaceport mixes open ground with metallic structures.

Typical cache zones:

• Dirt areas between landing pads
• Near broken cargo containers
• Around exterior service tunnels

Be careful—open sightlines make cache looting risky if other players are nearby.

4. Blue Gate: Raider Cache Map Location

Blue Gate has a mix of natural terrain and artificial barriers.

Look for caches:

• Along fence lines and barricades
• Near rock formations disturbed by storms
• At the edges of pathways leading between zones

Caches here often sit slightly off the main routes.

Tips for Farming Raider Caches

• Move with a plan—wandering wastes time and increases explosion risk
• Lower your movement speed briefly to hear audio cues clearly
• Check cache locations early in the match when competition is lighter
• Do not fight near exposed caches unless necessary

Efficiency matters more than combat when targeting Raider Caches.

Raider Caches are one of the most consistent ways to earn high-value loot in ARC Raiders, especially during the Uncovered Caches event. By learning the audio signals, recognizing visual markers, and understanding common spawn areas on each map, you can find caches faster and avoid unnecessary risks.

Knowing where to look—and when to move on—is what separates successful raiders from players who leave empty-handed.
