How to Get the Seeker Grenade Blueprint in ARC Raiders

The Seeker Grenade Blueprint currently drops on Stella Montis, but it does not have a guaranteed room, container or fixed spawn. Search dense container routes, extract as soon as the blueprint is secure, then learn it to craft Seeker Grenades at an Explosives Station. Loading Bay is a practical route—not a guaranteed blueprint location.

Seeker Grenade Blueprint quick facts

Where to find the Seeker Grenade Blueprint

Queue for Stella Montis and search normal loot containers throughout the map. Current databases list the blueprint as map-specific, while player finds span drawers, lockers, boxes, bags and other searchable containers. That spread is why a route with many interactions is more useful than camping one room.

Reports cluster around Loading Bay, Cafeteria and Security, but those are community-reported search areas. Neither day nor Night Raid guarantees the drop, and there is no dependable public percentage for the blueprint. Treat claims such as “open this green drawer for a guaranteed Seeker” as anecdotal.

A practical Stella Montis farming route

1. Choose Stella Montis. Do not spend blueprint-farming runs on a different map unless an update changes the loot pool.
2. Adapt to your spawn. Head toward the nearest dense interior route rather than crossing the whole map automatically. Loading Bay is attractive from a favorable spawn; Cafeteria or Security may be safer from another.
3. Open many container types. Check drawers, lockers, bags, boxes and breachable containers instead of relying on a single community favorite.
4. Move after a clean sweep. Rechecking an emptied room cannot improve the roll. Rotate through connected rooms while listening for Raiders and ARC.
5. Set an exit threshold. Once the blueprint drops, stop treating the raid as a loot-maximization run and plan the least exposed extraction.

Night Raid can be worthwhile if its broader rewards suit your objective, but higher danger is not proof of better Seeker Blueprint odds. For a solo route, value distance to cover and extraction more than theoretical loot density. The ARC Raiders solo-build guide has loadout ideas for surviving these rotations.

How to protect and extract the blueprint

• Use a secure pocket only if your current augment and the blueprint’s live item rules allow it; do not assume every loadout protects it.
• Avoid firing at ARC that you can quietly route around. Noise advertises your position to nearby Raiders.
• Prefer a nearby viable exit over a famous route that requires crossing exposed corridors.
• If the exit is active, clear angles first and keep enough stamina and healing for the final approach.
• After returning to Speranza, learn the blueprint before risking another raid.

Eliminating another Raider can yield a blueprint they were carrying, but it is an unreliable farm and adds unnecessary risk. Consistent container volume and successful extraction matter more.

How to craft and use Seeker Grenades

Once learned, the recipe produces one Seeker Grenade at an Explosives Station level 1 for 2 ARC Alloy and 1 Crude Explosives. The grenade releases a single homing projectile toward a nearby ARC target. It is useful for removing flying units and pressuring a priority machine without the multi-projectile cost of higher-tier options.

Do not throw it blindly into a mixed fight. Confirm the target is close enough for acquisition, keep cover between you and other Raiders, and remember that its single projectile does not make it a universal answer to large machines or squads.

What to do before the blueprint drops

Apollo can sell a limited number of completed Seeker Grenades, and some quests or Raider Deck rewards can award the usable grenade. Stock, prices, level gates and reward tables are volatile, so check the live trader or reward screen. These sources help you use Seekers before finding the recipe, but they do not replace the blueprint.

If you are farming other unlocks at the same time, compare the verified Vulcano Blueprint guide. For general progression, use the updated ARC Raiders leveling routes; blueprint hunting should not depend on unverified XP claims.

Seeker Grenade Blueprint FAQ

Is the Loading Bay a guaranteed location?

No. It is a container-dense community farming route. The blueprint can appear elsewhere on Stella Montis.

Can the blueprint drop during the day?

Yes. Community reports include both normal and Night Raids. No dependable evidence makes a Night Raid mandatory.

Can you buy the blueprint from Apollo?

Current data lists completed Seeker Grenades from Apollo, not the permanent crafting blueprint. Check the item name before spending coins.

Sources and update policy

Map and recipe details were cross-checked on August 26, 2026 against the current ARC Raiders Wiki item record and a second community-maintained item database. Container and POI observations were compared across multiple player reports and are labeled accordingly. We will update the route if Embark changes the Stella Montis loot pool or publishes a fixed source.
