As you travel through the ACE Chemicals plant in LEGO Batman: Legacy of the Dark Knight, you can collect a series of WayneTech caches. Each of these hidden treasure chests contains a single chip, which you can eventually put towards various gadget upgrades and unlocks when you return to your Batcave’s workbench.
Below, you’ll find the locations of all the WayneTech caches you can find at ACE Chemicals. See also: our guide to finding all the hidden Ace Cards to unlock one that you can display in your Batcave, and the location of the Red Brick in the ACE Chemicals level.
WayneTech Cache #1
In the room where you have to glide across the pool of toxic waste:
Before heading across, face away from the gap and grapple up to the higher ledge.
Follow the yellow arrows painted on the wall, gliding across a smaller pool of sludge, and find the first WayneTech chest in a small back room here.
WayneTech Cache #2
In the next room with the hanging chemical vats:
Grapple up to one of the swirling vats and jump down onto the pipe pictured above.
Follow the pipe until you find a vent leaking out toxic waste. Have Gordon shoot it to block the flow.
Jump onto the platform behind the pipe, head through the crawlspace, and find the WayneTech cache on the other side.
WayneTech Cache #3
In the room with the giant fan:
Use the fan to glide up to the platform, then shoot or Batarang the button to shut off the air flow.
Jump down to the bottom of the room to grab the WayneTech cache.
Press the red button to reactivate the fan and glide back up to reach the next area.
WayneTech Cache #4
This chest is found in the room with the giant vat of purple goo. Just head to this back corner to find it.
WayneTech Cache #5
While chasing Red Hood One:
Climb this ladder and use Batman’s Batclaw to pull the panel out of the wall.
Head through the newly revealed opening to find the final WayneTech cache.
With that, you’ve found all five WayneTech caches at ACE Chemicals, and gotten five new chips to boot: head back to the Batcave whenever you’re ready to spend those on gadget updates. Don’t worry if you miss one on the first go-around, as you can always replay the mission to pick up whatever you may have left behind in LEGO Batman: Legacy of the Dark Knight.
