Tricorner WayneTech Caches in Lego Batman: Legacy of the Dark Knight

Tricorner is one of Gotham’s denser collectible zones in Lego Batman: Legacy of the Dark Knight, and its 20 WayneTech Caches hold the chips you need to upgrade gadgets back at the Batcave. Most caches open the moment you walk up and interact, but a handful are gated behind specific character abilities, including Catwoman, Batgirl, Nightwing, Gordon, Talia, and Robin.

🦇

Quick answer: There are 20 WayneTech Caches in Tricorner. Roughly half are pickups you can grab immediately. The other half are short puzzles tied to a specific bat-family character’s gadget.

The non-puzzle caches don’t need any special prep. Walk up, press interact, and the chip drops straight into your total. The rest are covered below in the order they appear on the map.

Pier A battery puzzle (115, 119)

This one is the only Tricorner cache that needs a manual puzzle without a bat-family unlock. The battery is sitting behind you when you face the cache, so grab it before you start hunting for targets.

Pick up the battery near the cache and carry it to the main entrance of the Pier A building.

Slot it into the socket. Several Batarang targets will appear around the door frame.

Throw a Batarang at each target to reroute the power. The cache pops open once the circuit completes.

Catwoman cache (163, 156)

You need Catwoman unlocked, since this puzzle uses her wall-climb and her claws to cut reinforced glass.

Move to the right of the cache and scale the climbable wall to flip the first switch.

Drop back down and head left. Use Catwoman’s claws to cut through the glass panel blocking the side room.

Hit the second switch inside the room. Both switches active will release the lock on the cache.

Batgirl cache (136, 182)

Batgirl’s drone is the key here. The puzzle hides a code above the hacking point, and only her drone camera can see it.

Follow the camera wire from the cache back to the hack terminal it leads to.

Launch the drone and fly it up above the terminal until the code becomes readable.

Punch the code into the hack panel to release the cache.

Nightwing cache (185, 196)

Nightwing’s escrima sticks double as a power source for these wiring puzzles. The conductor in the middle needs to be repositioned before you can complete the circuit.

Push the conductor to the right side of its track.

Run one hook from the power source to the conductor, then a second hook from the conductor to the battery.

Walk back to the power source and charge it with Nightwing’s weapon. Electricity flows through, and the cache unlocks.

Conductor alignment cache (205, 205)

No character lock on this one, just a quick alignment puzzle with two rotating conductors.

Rotate the right-hand conductor so its handles line up with the indicator light on top.

Do the same with the middle conductor. Once both are aligned, current flows and the cache activates.

Gordon cache (199, 182)

The building next to this cache is on fire, with a leaking liquid pooling around the base. Gordon’s foam tool clears both hazards.

Switch to Gordon and spray foam over the flames until they go out.

Cover the leaking liquid with foam to neutralize it.

Hit the switch that becomes accessible once the fire is gone. The cache opens.

Talia cache (254, 197)

Talia is unlocked later in the story, so this one is usually mopped up on a return trip. Her dash teleport is the only way past the gap.

Use Talia’s pole-dash ability to chain across the poles toward the lock.

Teleport to the lock at the end of the chain and break it.

Pull the switch behind the lock to release the cache.

Robin cache (279, 167)

Robin’s Batarang has slightly different targeting behavior, and this puzzle wants three hits in a precise order.

Position Robin so all three targets are visible in front of the cache.

Throw Batarangs to hit the targets from left to right. The order matters; hitting them out of sequence resets the puzzle.

The cache pops open on the third correct hit.

How to confirm you have all 20

Open the map and filter for WayneTech Caches in the Tricorner district. The counter at the top of the collectibles tab should read 20/20 once everything is opened. The chips themselves feed directly into gadget upgrades at the Batcave’s WayneTech terminal, so there’s no separate redemption step.

If your counter is stuck below 20, the missing cache is almost always one of the character-locked puzzles. Sweep the eight puzzle coordinates listed above with the right hero loaded into your active duo, and any holdouts should close out quickly.
