The first part of the ‘Riddler’s Revenge’ Most Wanted mission can be found inside a Riddler Garage (it’s the one with all the question marks – very hard to miss!) located at the train yard just east of the GCPD HQ building on Bleake Island.
Enter the garage door with all the green question marks at the map icon on the map. This will act as an elevator and take you down to a challenge below.
As soon as you can get off the elevator, move forward and park in front of the bollards blocking the path. The Riddle will appear on the screens here and eventually give you Riddler Access Code which we can use to open the door ahead, although sitting still for a few minutes will reward you with a fairly amusing monologue.
When you are ready to go, head through the door and you’ll find a starting line. Yep, we’ll need to do a race of sorts. We’ll have to complete three laps of the course, completing each within a certain time limit. As you drive through the course, you’ll need to use the Riddler Access Code we received earlier to add/remove/move obstacles, ramps and platforms on and off the race track.
In this race we’ll be able to control the large white and red doors/platforms with the access code. Each of the three laps is slightly different, with the addition/removal of additional obstacles/platforms to make things increasingly difficult. Fortunately this race is pretty straightforward and aside from the need to drive along the wall when the floor gives way in the first tunnel on the final lap, there are only a couple of tricky jumps involved and if you get stuck, try playing with the Riddler Access Code to find a way through.
Once you have successfully complete the third lap, the Riddler will praise you and activate a pressure plate near the starting line as a reward.
Step on the pressure plate with Batman and note the lights on the wall – the green light is most important. If you switch to Catwoman at this point you will notice that the lights on the wall are in the same pattern as a series of pedestals with keys. The red light pedestals are bad! Make sure you find and interact with the green pedestal to continue.
Don’t worry if you can’t quite figure it out right away as you’ll be able to switch between the two characters as many times as you like to make sure you get the correct key. Head up and interact with the pedestal that matches the green light to continue.
Successfully complete the first Riddler trial.
