On Dam Battlegrounds, the Matriarch is no longer in the old central “Breach” lane between Power Generation and the Control Tower. Instead, it now spawns out on the south‑west edge of the map, in the dry desert area by the water towers and the Electrical Substation.

Current spawn spot

  • Look for the desert‑like basin on the south‑west side of Dam Battlegrounds, away from the main dam structures.
  • Key landmarks are:
    • The cluster of water towers along the western rim.
* The nearby **Electrical Substation** complex right next to those towers.

* A small enclosed building closer to the water‑treatment elevator, just north‑east of the substation.

The Matriarch usually sits in the open ground between these structures and will wake up as soon as it detects movement or incoming fire, so approaching across the flat sand is extremely dangerous.

How to home in on her

  • If Shani has a special Matriarch voice line at the start of the raid, that means the Matriarch event is active; if you’re on Dam Battlegrounds when you hear it, she is somewhere on this map.
  • Climb a tall point near the western side of the map (for example the Control Tower or other high platforms) and scan toward the water towers/substation; the Matriarch’s huge silhouette and missile trails are visible from far away.

In short: load into Dam Battlegrounds when the Matriarch event is live, head to the south‑west desert around the water towers and Electrical Substation, and you’ll find her patrolling that open basin.

Wondering where the Matriarch is on Dam Battlegrounds in ARC Raiders? She now spawns on the south‑west desert edge by the water towers and Electrical Substation, not the old central Breach lane.
