This next spot is kind of odd as you must assemble a swan into a boat. Steer around the mines, and get to the other side. There is a gate on this side, and Riddler needs to mind control some people on the other side. An oxygen tank on one side needs to be smashed. There will be a red thing there that the man can step on, and the gates will open. The other tank thing needs to be smashed, and built to a lever to open the door to the next area.

This next area has a canister in a glass box, but you cannot get it now.

This area also has some toxic waste that Ivy can walk across safely, but Riddler can’t. Go ahead and smash some areas on the right and build a car, then drive that car over to Riddler. Riddler can drive over the waste, and go to his window, where a door will open to the next area.

This next area, Ivy has to go through gas and jump up to a pressure point to stop the poisonous gas. Riddler needs to follow her closely. The next area has to have Ivy step on a pressure point and pull a lever. A vault door will open, and the characters can go through it. There is a hot pipe close by here, and it is significant, but there isn’t any way to get to it.

In this next area, an elevator will need to be built. It won’t be complete unless Ivy uses here plant-growing powers on two pots. A tall plant will grow, then a shorter on the right. Ivy needs to jump up on the short one, then the tall one, then on a level higher. She can bash some stuff, then build the doors needed here.

Both characters an now get in the elevator, and go to the next level. This one requires the use of a few pressure platforms. The first is obtained by using the Riddler’s mind control on a man who will push something off the tiles. This is a generator that can be built, and standing on the green light will cause something nice to happen. This will result on standing on the other green light. The final area is fixing something on the right, and then jumping up and down until a certain generator makes contact, which is above the platform, by the way.
