This is for beating the fourth Riddler challenge which can only be accessed after beating the third.
This is a circuit race requiring you to do three laps of a circuit as it gets increasingly harder.
There are only two obstacles ;
A) roof levers - these are the big levers that you control with
. As one set goes up, another goes down.
Ensure you raise the ones you need before hitting them, but don't collapse a roof if you are in its fall zone.
B) random green spikes - these come down randomly and you have to dodge them. The position they are going to strike at is marked by the floor turning green.
There is plenty of leeway on the time, so you should get it no problem.
Complete all three laps then stand on the pressure pad.
Check the map , locate the correct cabinet using batman and then pick the correct key up with catwoman for your achievement,
