What to know

  • Community-wide goal – The event is global: all players contribute to a shared progress bar, beginning November 13, 2025.
  • Materials required – Players donate common crafting materials: Metal Parts, Fabric, Plastic Parts, Rubber Parts, Chemicals.
  • Event currency: Merits – For each donation (e.g., sets of 5 items) you receive Merits; there is a cap (in Phase I you can earn up to 900 Merits).
  • Phased unlock – Once the required community total is reached (Phase I), the new map Stella Montis unlocks and the event moves to Phase II (Staking Our Claim) with personal progression and reward tracks.

In the November 2025 “North Line” update for ARC Raiders, developer Embark Studios introduced a major community event called Breaking New Ground, which is the first phase of the Stella Montis Community Event. The goal: the entire player base works together to gather specific resource materials, donate them via the in-game “Live Event” interface, earn “Merits” (an event currency) and unlock the map Stella Montis, a previously inaccessible research facility high in the mountains. Once Phase I is complete, Phase II (“Staking Our Claim”) begins with new progression tracks and rewards.
