In LEGO Batman: Legacy of the Dark Knight, players can hunt for various Red Bricks, with one of the earliest found in ACE Chemicals during the Red Hood Gang arc. If players missed this collectible, they can replay the mission using the Batcomputer in the Batcave. To locate the Red Brick, players should progress until they receive the 'Follow the bears' objective, leading them down a narrow hallway where they can spot the Red Brick behind glass in a pipe. Upon reaching the end of the hallway, players should turn right into a crawlspace. Using Gordon, they must spray foam on the pipeline to free the Red Brick from its stuck position. After clearing the leaks, players can use Batman to open a hatch and collect the Red Brick. This collectible unlocks the Toxic Waste Modifier, which is essential for achieving 100% completion in the game. The game was released on May 22, 2026, and is available on multiple platforms.
