Use the route below as a historical walkthrough, not a guarantee that the event or map is still live: the Roblox listing checked October 8, 2026, does not confirm that the hunt remains available.
Before you start
The circuits are described as bright green circuit boards hidden around the event areas—not items to buy from a shop. The location guides differ on some landmarks, so check the in-game counter after each pickup and use the alternate clues below if a spot does not match your map.
The route below follows Destructoid’s January 21, 2025 walkthrough. It reported that finding all nine awarded 1,000 XP and 500 Batteries; treat those amounts as guide-reported rewards and verify them against the in-game tracker.
Where to find the nine circuits
Play area
- At the enemy spawn portal: Check the portal where enemies enter the play area.
- In the arena center: Look around the middle of the arena.
- Behind a rock formation: Search around the rocks for a partially obscured board.
Portals, Ranked board, and Summon Unit area
- Behind the Toilet Fortress portal: Check behind the portal leading to Toilet Fortress.
- Behind the Ranked mode board: Look near the Apocalypse City map area.
- Beside the Summon Unit area: Check next to a wooden block.
Trading Plaza
- At the left archway: Search beside a pillar at the left arch in the Trading Plaza.
- Near the far-end wooden statue: Look beside the statue.
- Above the water: Check the top of a statue standing in the water.
If the landmarks do not match your map
A separate January 18, 2025 guide gives alternate clues and a different arrangement. These are useful places to search if the numbered route above does not fit your version; do not assume the two guides describe one confirmed sequence.

- Tech City: Search beside the portal, at an intersection, and beside a gray cone-shaped structure.
In either route, inspect behind portals, rocks, boards, and structures, as well as elevated spots. Let the in-game counter—not a guide’s numbering—confirm whether you have collected each board.
Is the Defense Tech circuit hunt still available?
Availability is not established. The Roblox experience listing checked October 8, 2026, mentions a new lobby and summer event but does not confirm the Defense Tech circuit hunt. If the event area or its tracker is absent in your game, this historical route may no longer be usable.
