I dropped into Blue Gate with a single goal: three stars before the lobby emptied. The Locked Gate had just spawned and the chat was already trading locations. I want you to finish faster than the other teams—here’s how I’d run it.
Week 19 Trials: the moment the server chat goes loud
Monday mornings in ARC Raiders mean every squad is checking the Trials feed the second the server resets.
I’ve played these trials enough to know the pattern: five small tasks stretched across maps, each one forgiving if you box-plan your route. Below I walk you through each objective, the fastest ways to hit three stars, and the little habits that stop useless trips across the map.
How do I get three stars in ARC Raiders Week 19 Trials?
Three stars come from stacking efficiency: pick a route that links objectives, force the right events, and farm high-density encounters. Start with the Locked Gate on Blue Gate when it spawns, clear the Traffic Tunnels for container opens, then chain Matriarch or swamp runs for ARC kills.
Open containers inside the Traffic Tunnels: a single map event changes everything
You’ll hear players calling “Locked Event” before you see the icon.
The Locked Gate spawns on the Blue Gate map. When it’s active you must find four keys scattered at named POIs—Reinforced Reception, Raider’s Refuge, Pilgrim’s Peak, and Ancient Fort—then bring them to the Checkpoint POI to open the gate. The gate reveals the Traffic Tunnels where a Bastion guards a cluster of loot. Kill the Bastion, then focus on vehicles, side bays, and containers to rack up container opens quickly. If you open enough containers in one run, the stars fall into place.
If you’re solo, drop at one of the four POIs to grab keys fast and then sprint to Checkpoint. If you’re in a squad, split: two grab keys, one holds the gate point, one clears the Bastion and containers. The Locked Gate is a silver keyhole in a fortress—treat it like a timered objective and plan your loots accordingly.
How do I open containers inside the Traffic Tunnels?
Wait for the Locked Gate event, collect the four keys from the named POIs, and bring them to the Checkpoint POI. Once the gates are open, wipe the Bastion, then methodically open every vehicle and side bay. If you clear the area in one sweep you’ll hit the three-star threshold much faster than bouncing across maps.
Search Raider Caches: map edges contain the easiest points
Raiders tend to hide their caches on the outskirts—players frequently check perimeter paths first.
Raider Caches spawn on all maps and haven’t changed in Season 3. Hit the usual outskirts POIs and scan rooflines, cargo piles, and small outbuildings. First Wave Raider Caches were added recently and count for the same task; treat them as bonus targets. Raider Caches are hidden pockets sewn into the map’s hem—if you sweep edges while looping toward other objectives, the cache count climbs without extra runs.
Where are Raider Caches located?
They’re usually along the map edges and in small POIs: warehouses, satellite dishes, and feeder roads. If you’re on Spaceport, sweep the hangars and perimeter buildings first. Use the ARC Raiders Wiki or the game’s community Discord to mark known cache clusters on your map before dropping.
Damage Rocketeers, Leapers, or Bastions: big targets, fast progress
High-health ARCs appear randomly, but event spawns are the reliable option.
Your best bet is joining a Matriarch event—the Matriarch spawn guarantees Rocketeers, Leapers, and Bastions in the same fight, so you can hit the damage tally in one go. Use hard-hitting weapons: Jupiter and Equalizer are ideal if you’ve got them, but Hullcracker remains a reliable staple for heavy DPS. Focus fire on one ARC at a time, kite when necessary, and collect assists if you’re not the final blow scorer.
Destroy Ticks: small targets, rapid completion
Ticks are the easiest ARCs; you’ll often clip a bunch while clearing rooms.
Ticks die to a single weapon hit or a pickaxe smash. If you need the count fast, run Stella Montis and open interior rooms; the density there raises your encounter rate. A couple of quick raids and that star is done.
Destroy ARC enemies in the Swamp: concentrated kills with fewer trips
Swamp zones tend to produce clustered ARC encounters, so hits add up fast.
Head to the Dam Battlegrounds map and focus on the Hydrophonic Dome Complex, Old Battleground, and South Swamp Outpost. Any ARC you destroy in those swamp locations counts. If you time an ARC encounter there, clear it fully—one clean sweep often secures the star without another map hop.
Tools I use: the ARC Raiders Wiki for spawn patterns, the subreddit for quick map notes, and the official Discord for Matriarch timers. If you pair those with a simple routing rule—prioritize event spawns, sweep edges on the way to objectives, and force clustered ARC fights—you’ll shave runs down and hit three stars reliably.
Ready to test that route and post your best run on Discord—or will someone else beat you to the lobby bragging rights?
