ARC Raiders Event Timer — South America

ARC Raiders features 15 different map conditions (events) that rotate across all battleground maps throughout the day. Events typically last 60 minutes and rotate hourly, with different conditions appearing on different maps simultaneously.

Since the patch 1.42 update (August 2026), each regional server (Europe, North America, South America, Asia, Oceania) runs the same event rotation shifted by several hours. Times on this page reflect the South America server — use the region selector above if you play elsewhere.

Boss events like the Matriarch and Harvester are extreme-threat encounters that spawn powerful ARC enemies with the best loot drops in the game. Close Scrutiny (Flashpoint update) introduces the ARC Assessor and Vaporizer with high-risk, high-reward mechanics.

Environmental conditions like Night Raid, Cold Snap, Hurricane, and Electromagnetic Storm change the map's environment, affecting visibility, temperature, or electronics. Night Raid and Cold Snap are particularly popular for blueprint farming.

Loot events like Uncovered Caches, Locked Gate, Launch Tower Loot, and Prospecting Probes reveal bonus loot locations across the map, making them ideal for material farming runs.
