Map conditions are one-hour variants of an ARC Raiders map that Embark rotates on a published schedule. Night Raid is the one most players chase: Embark calls it a scenario with better loot, and it currently runs on five of the seven maps, not Dam Battlegrounds or Spaceport.
Each condition changes something different, from lightning that leaves loot behind to a Frigate you can board. Below is which conditions run where, what Embark says each one does, and how to catch the one you want, checked on 9 October against Embark's map conditions schedule and patch notes.
Which conditions run on which map
This is the rotation on Embark's schedule in the week Frozen Trail launched, most frequent first. The ARC Frigate is live on one map in every hour of the day.
| Map | Conditions on the current rotation |
|---|---|
| Dam Battlegrounds | ARC Frigate, Prospecting Probes, Harvester, Uncovered Caches, Electromagnetic Storm, Matriarch |
| Buried City | Bird City, ARC Frigate, Night Raid, Prospecting Probes, Hurricane |
| Spaceport | Electromagnetic Storm, ARC Frigate, Matriarch, Harvester, Launch Tower Loot, Prospecting Probes |
| The Blue Gate | ARC Frigate, Harvester, Night Raid, Electromagnetic Storm, Matriarch, Uncovered Caches, Prospecting Probes, Close Scrutiny |
| Riven Tides | Beachcombing, Night Raid, Uncovered Caches |
| Stella Montis | Night Raid |
| Pendola Pass | ARC Frigate, Night Raid, Redirection |
Embark sorts conditions into two kinds. Major conditions change how the raid plays: ARC Frigate, Close Scrutiny, Electromagnetic Storm, Hidden Bunker, Hurricane, Locked Gate and Night Raid. Minor ones add an event or a loot source to an otherwise normal map.
Night Raid: what actually changes
Plenty of guides promise extra keys, meaner ARC or a loot multiplier at night. Embark has said none of that. Here is what it has confirmed:
- Better loot: Embark describes Night Raid as one of the "scenarios that have better loot". It has never put a number on it.
- No free loadout: since 16 June, free loadouts are blocked on Night Raid, so you drop in with your own gear at risk. It started as a three-week test, and Embark has kept it since.
- A different ARC mix: a March patch increased the variety of Leapers, Bombardiers, Bastions and Rocketeers during Night Raid.
- Darker Stella Montis: most lamps are off at night there, which makes flashlights and listening matter more.
When Night Raid runs
Stella Montis gets Night Raid most often. The Blue Gate gets it least, and its two windows land about half a day apart. Hours per day were similar in every region.
| Map | Night Raid hours a day | Usual gap between windows |
|---|---|---|
| Stella Montis | About 6 | 1 to 8 hours |
| Pendola Pass | About 3 | 1 to 10 hours |
| Buried City | About 3 | 6 to 13 hours |
| Riven Tides | About 2.5 | About 8 hours |
| The Blue Gate | About 2 | 12 to 13 hours |
Dam Battlegrounds and Spaceport had no Night Raid on the current rotation, though older guides still list both.
The major conditions
ARC Frigate
One of ARC's largest ships patrols the map. Find a way aboard, work through its passageways and unlock paths while fighting ARC, including the new Hydra turret. It's one of only two places Amplification Modules drop.
Electromagnetic Storm
Lightning strikes the map, and Embark says a strike sometimes leaves a valuable item behind. Runs most on Spaceport.
Hurricane
Wind batters you, flying debris wears down your shield and visibility drops. It also unearths First Wave Raider Caches, which favour high-tier materials.
Close Scrutiny
Less loot lies around the map, but ARC Assessors carry the riches, with Vaporizers around the operation. Free loadouts are blocked here too. Currently on The Blue Gate.
Locked Gate
Security Codes come from Code Printers and expire when you extract. Some side entrances open with the main gate. On Embark's list, but not on this week's rotation.
Hidden Bunker
Activate the rooftop antennas and the bunker opens after a short delay, with blueprints you only find during this condition. On Embark's list, but not on this week's rotation.
The minor conditions
Beachcombing
Sweep a Dockmaster's Detector across the sand to dig up buried loot. You earn the detector from the Avian Alarm project.
Bird City
Nests in the chimneys hold trinkets, with more bird traps, more ziplines, more flying ARC and more Raiders nearby than usual.
Launch Tower Loot
The rooftop activity has a better chance of high-tier loot while this is live.
Redirection
New in Frozen Trail, on Pendola Pass only. Embark hasn't detailed what it changes yet.
Harvester, Matriarch, Prospecting Probes, Uncovered Caches and Lush Blooms are on Embark's list too. Embark hasn't published what they change beyond their names, so we've left them out rather than guess.
How to catch the condition you want
- Set your region first: Embark's page defaults to Europe. Oceania gets each slot 9 hours before Europe, Asia 5 hours before, South America 6 hours after and North America 7 hours after.
- Use the bell: click it on any upcoming condition for a browser alert when it starts. Alerts only fire while the page is open.
- Watch the game too: the in-game countdown appears 60 minutes ahead, and your party can see live conditions in Speranza and ping where to go.
- Plan a day ahead: the rotation repeats roughly every 25 hours, so a slot you missed tends to come back about an hour later the next day.
Want an operator for Night Raid?
Map runs come in Day, Night or a mix on the five Night Raid maps, booked into the windows on your server region. Frigate runs put our operators on the ship with you.

Map condition questions
How long does a map condition last in ARC Raiders? One hour. Every condition on Embark's schedule runs in a one-hour slot on one map, starting on the hour.
Which map has Night Raid most often? Stella Montis, with about six Night Raid hours a day, the only condition on its rotation.
Do map conditions give double Trials progress? Not any more. Embark removed the bonus for major conditions in Trials Season 4 in April 2026.
Is Cold Snap still in ARC Raiders? Not right now. It isn't on Embark's current list of map conditions.
