: Copper x2
Once in control, remove the container van by pulling it out of the way. Next, pull yourself to the car but don't stomp on the container vans ahead yet. Glide to the area to the left to find a copper key.
Shipyard Copper Key, The Trade
Get back to the container vans and stomp on them three times to clear the path. The dock will start to collapse so keep swinging across until you reach the warehouse. Once there, quickly kill the enemies and use demon pull to remove the ship's propeller and save Virgil and Kat. Continue escaping the collapsing buildings until the car slows down before hitting the train.
There's a second key that you can get during this sequence so we'll have to get that first. Pull the bus ahead to create a foothold then check the platform to the left to find the copper key above.
Street Copper Key, The Trade
Continue to where the car is headed then kill the enemies blocking your path. Reach the train bridge's foundation then smash it with Eryx
