Sinister Strip is already one of the best drop spots in Fortnite Chapter 7 Season 3, but most players completely miss the locked prison cell hidden in its basement. Crack it open and you’re looking at a near-guaranteed Mythic Limitless Seven Sliders, a chunk of XP, and a possible Vault Key, all within the first two minutes of a match. Here’s exactly how to do it.
| Detail | Info |
|---|---|
| Location | Sinister Strip (northeast building) |
| Method | Deactivate 2 power grids via sewer wires |
| Loot | 2x Rare Chest, 2x Regular Chest, 1x Sprite |
| Key Reward | Mythic Limitless Seven Sliders (near-guaranteed) |
| Bonus Reward | 1,000 XP (Path of Least Resistance quest) |
Head to Sinister Strip and locate the large building directly opposite the giant Sprite hologram structure at the center of the POI. Enter from the south gate and go down the staircase to the basement. You’ll find the locked prison cell behind a reinforced door — the bars are electrified and the door is sealed until you kill the power.
Stand in front of the locked door. You’ll see two thick red wires running from either side of the door. Follow the wire going left. Drop down and trace it through the sewer tunnels below. The path branches several times, but just keep the wire in sight and you won’t get lost. Eventually you’ll hit a vent — open it, pass through, and you’ll reach the North Prison Security Grid. Interact with it to deactivate.
Return to the locked door and now follow the wire going right. Head back into the sewer and trace it through the tunnels. You’ll pass a gnome sitting in the tunnel — that’s your confirmation you’re on the right path. Find the second vent, open it, and deactivate the South Prison Security Grid.
Important: Both grids must be offline before the door unlocks. Don’t head back early.
With both grids shut down, the electricity on the door disappears and you can walk right in. Completing the unlock also triggers the Path of Least Resistance quest, rewarding you with 1,000 XP on the spot.
| Item | Quantity | Notes |
|---|---|---|
| Rare Chest | 2 | Primary loot source |
| Regular Chest | 2 | Standard loot |
| Sprite | 1 | Random type |
| Mythic Limitless Seven Sliders | 1 | Near-guaranteed from Rare Chest |
| Epic Vault Key | Possible | Opens Dark Voyager’s Vault in Sinister Strip |
The Mythic Limitless Seven Sliders is the real prize here. Unlike normal sliding in Fortnite, which has a hard distance cap, this item removes the limit entirely — letting you slide indefinitely. It’s one of the most broken mobility items in Chapter 7 Season 3, useful for rotating through storm, escaping third-parties, and maintaining speed while aiming. The drop is near-guaranteed, making this one of the most reliable Mythic sources on the map that doesn’t require fighting a boss.
The Epic Vault Key from the Rare Chest opens the Dark Voyager’s Vault, also inside Sinister Strip, for even more high-tier loot.

It’s in the basement of the northeast building at Sinister Strip, the one directly opposite the large Sprite hologram structure. Enter from the south gate, go down the stairs, and you’ll find it at the bottom.
You get 2 Rare Chests, 2 Regular Chests, and a random Sprite. The Rare Chests have a near-guaranteed drop of the Mythic Limitless Seven Sliders and a chance to drop an Epic Vault Key for Sinister Strip’s Dark Voyager Vault.
Follow the two red wires from the locked door into the sewers below. Each wire leads to a power grid — deactivate both (North and South Prison Security Grid) and the door unlocks.
It removes the normal sliding distance cap, letting you slide continuously. It’s excellent for rotations, escaping zone, dodging fights, and maintaining movement speed while shooting.
Yes. Completing the unlock triggers the Path of Least Resistance quest, which rewards 1,000 XP immediately.
