While playing the campaign in Teardown, the Löckelle Teardown Services facility is your home base, where you have a TV to catch up with the news (also includes advertisements from the game's story) and a computer to read messages and accept missions from people. Your home base also starts to change
over time due to some improvements made by the head of the Löckelle Teardown Services company, Tracy, who is your mother. For instance, the rusted car inside gets repaired over time until it becomes a fully functioning car.

Lee Chemicals is a large chemical plant built near a river and a dam with a hydroelectric power plant. Owned by Lawrence Lee Jr., who was tracked by the police for tax evasion for months. Parisa Terdiman, one of the police officers who have been investigating him, asks the player to acquire evidence for her, such that enough information could get Lee convicted.
