The ARC Raiders event schedule isn't a fixed timetable you can memorise. It's a live server rotation, and each map rolls its own condition. If you're planning a raid around particular gear, checking the current ARC Raiders Items available to you can help, but the map tracker matters more. Conditions usually run for about an hour, although downtime can appear between rotations. A Night Raid on Dam Battlegrounds doesn't mean Spaceport will get one too.

How the Rotation Works

Dam Battlegrounds, Spaceport, Buried City, Blue Gate, and Stella Montis all run conditions in parallel. They don't share a neat hourly timetable. That's why old screenshots and saved Discord messages cause so much confusion. You might load into one map during a storm, find another running a loot event, and see no modifier at all on a third. The sensible move is to check a live conditions tracker just before you queue.

Choosing the Right Condition

Night Raid and Electromagnetic Storm are the main picks for weekly Trials because both double Trials points. Night Raid brings darkness, fewer extraction options, and more aggressive ARC units. Electromagnetic Storm adds rain, lightning, and masked footsteps, so staying in the open can be a bad idea. Hidden Bunker, found only on Spaceport, also grants double points despite being labelled Standard. You'll need to align four antennas before reaching its better loot, so a squad has a much easier time.

Loot, Blueprints, and Map-Specific Objectives

Not every useful condition is classed as Major. Harvester is the key event for the Equalizer and Jupiter legendary blueprints, while Matriarch offers an elite-loot boss encounter. Prospecting Probes is handy for mechanical parts, Husk Graveyard spreads ARC components across the map, and Lush Blooms helps with nature resources and cash. Locked Gate is exclusive to Blue Gate and matters for Trials involving mine disarming. On Buried City, Close Scrutiny raises PvP pressure around choke points, while Hurricane can disrupt movement, stamina, throwables, and shields.

What to Check Before You Deploy

Spaceport's Launch Tower Loot is better suited to organised teams, and Uncovered Caches rewards players who already know where sealed containers sit. Bird City is unusual because it follows a weekly cycle rather than the normal hourly rhythm. Beachcombing was added with the Riven Tides update and remains tied to that location. Conditions have continued to expand through updates such as Flashpoint, so relying on a familiar pattern is risky. Check the active map, match the event to your goal, and leave room for a quick extraction.
