ARC Raiders Event Timer

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.

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

Environmental conditions like Night Raid, Cold Snap, Hurricane, and Electromagnetic Storm change the map's environment, affecting visibility, temperature, or electronics. These conditions create unique gameplay opportunities — 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.
