This week's ARC Raiders trials are mostly easy if you stop wasting time on bad targets. The fastest clears come from Bastions, Salamantis Shredders, clean Heavy Fuse Grenade placement, and smart event timing for ARC Probes and Snitches.

The goal is simple: hit the highest-value targets, avoid contested farms, and leave bad map conditions immediately.

↖ Heavy Fuse Grenade Trial: Best 3-Star Method

The mistake is throwing Heavy Fuse Grenades at armor. Don't do that.

You want the grenade trapped near weak areas.

↖ Best Heavy Fuse Grenade Targets

In our runs, one grenade landed under 3,000, while another broke 4,000 from better placement. Same tool. Different result. Placement is everything.

↖ Key Rule

Heavy Fuse Grenade damage does not stack.

Throwing multiple grenades at the same ARC does not combine the score. Each grenade is a separate attempt.

If the first throw is bad, the second can still clear it. But more grenades will not fix poor placement.

↖ Best Execution

• If you find a Queen or large ARC event, get above it.
• Break the top panel.
• Drop the Heavy Fuse Grenade inside.
• If no event is active, use a Bombardier and throw underneath it.
• Aim to hit the legs and rear weak point.

Result: easy 3-star without needing perfect setup.

↖ ARC Probe Trial: Fastest Way to 3-Star

ARC Probes are simple once you know the scoring.

Crashed probes are safe. Landed Prospecting Probes are faster.

↖ ARC Probe Scoring

A crashed probe gives 667 points, so five crashed probes can finish the trial.

But during Prospecting Probe events, landed probes are better. Each one has three lootable sides after breach.

↖ Best Probe Routes

↖ Important Warning

When you breach a landed probe, it can call in ARC. Sometimes twice.

It also pulls nearby ARC until the breach finishes. This can snowball fast.

If you find a landed probe:

• Clear an escape path first.
• Start breach.
• Loot all three sides.
• Leave if ARC pressure gets ugly.

These probes are also great for ARC circuitry and Advanced Electrical Components, so loot them properly.

↖ Snitch Trial: Best Farming Spots and Loadout

This is the slowest trial if you pick the wrong map.

Each Snitch gives only 300 points. You need about 10 Snitches for 3-star.

That means contested spawns ruin the run.

↖ Best Snitch Map Conditions

In our testing, Snitches felt close to a 4-minute respawn in some spots. If nothing appears, rotate. Do not sit there hoping.

↖ Best Snitch Weapons

If other Raiders are shooting the same Snitch, Seeker Grenades help secure credit while it bounces around.

↖ Best Hidden Bunker Spot

Use the roof of the departure building.

From there, we can watch around four Snitch spawns consistently.

But this spot gets contested. Bring:

• Jupiter or Osprey
• Seeker Grenades
• Zipline or safe mobility tool

The roof is strong, but getting down can be awful if a Vaporizer or Watcher pressures you. Do not risk the whole trial on a bad drop.

↖ Snitch Rule

If Hidden Bunker is active and quiet, farm it.

If it is crowded, switch to Electromagnetic Storm or do another trial first.

↖ Salamantis Ground ARC Trial: Farm Shredders

This one is easy. Do not overthink it.

Kill Shredders. Ignore low-value trash unless it is already in your path.

↖ Salamantis Point Values

You need around 8–9 Shredders for 3-star, with small enemies adding extra progress along the way.

↖ Best Execution

• Prioritize Shredders immediately.
• Kill Fireballs if nearby.
• Do not chase Ticks.
• Rotate if other Raiders are clearing the same area.
• Use explosives when ARC groups stack up.

The only real threat is competition. If another squad is farming with heavy explosives, move. Empty ground is wasted time.

↖ Bastion Trial: Fastest Damage Route

Bastions are one of the cleanest 3-star trials this week.

One Bastion gives around 2,250 points with proper damage. You usually need one kill plus partial damage on a second.

↖ Best Bastion Method

Do this every time:

1. Shoot the leg weak point.

2. Move behind the Bastion.

3. Place Deadline on the exposed weak point.

4. Finish damage or rotate to the next Bastion.

Simple. Fast. Reliable.

↖ Best Bastion Farming Route

The Power Generation Complex to Dome Complex loop is efficient because the locations are close and Bastions appear to work around a 5-minute respawn.

↖ Best Bastion Loadout

If the area is contested, rotate. Fighting over one Bastion is slower than finding the next one.

↖ Best Weekly Trial Priority

Do the reliable damage trials first. Save spawn-dependent trials for good conditions.

If Hidden Bunker is active and quiet, bump Snitches up. If not, don't force it.

↖ Common Mistakes to Avoid

↖ FAQ

↖ What is the fastest weekly trial to 3-star in ARC Raiders?

Bastion damage is the fastest for most players. One Bastion gives around 2,250 points, and a second partial damage cycle is usually enough for 3-star.

↖ How many Snitches do you need for 3-star?

You need about 10 Snitches. Each gives 300 points. Farm Hidden Bunker if active, or use Electromagnetic Storm as the safer backup.

↖ Do Heavy Fuse Grenades stack damage?

No. Heavy Fuse Grenade damage does not stack. Each grenade is scored separately, so placement matters more than quantity.

↖ How many ARC Probes are needed for 3-star?

You need five crashed probes at 667 points each, or usually two landed Prospecting Probes if you loot all three sides after breach.

↖ What is the best target for Salamantis ground ARC damage?

Shredders. They give around 350–380 points each. Fireballs and Ticks are only bonus progress and are not worth chasing.

↖ Summary

This week's ARC Raiders weekly trials are quick if you farm the right targets.

Start with Bastions using Deadline on the leg weak point. Then clear Salamantis ground ARC by farming Shredders. Use Heavy Fuse Grenades only on trapped weak-point setups, not armor.

For ARC Probes, wait for Prospecting Probe events when possible and loot all three sides. For Snitches, use Hidden Bunker or Electromagnetic Storm, bring Jupiter/Osprey, and rotate if spawns are contested.

The clean route is simple: high-value damage first, event-based objectives second, contested farms last.
