The fourth riddle is located beneat the Elliot Memorial Hospital, but in order to get to it, you need to find the Own the Roads side mission nearby. Clear that one and the walls will drop, allowing you to drive your Batmobile inside and take the elevator down to the next riddle. This will be another race, aptly named The Crushinator, which has you switching back and forth between the red and white sets, while also trying to avoid green blocks coming down to try and make the Batmobile into scrap metal.
This race is another three laps, with each one getting slightly harder than the previous one. Once you've managed to do the first one or two laps, you should have a fairly grounded idea on how to go through without too much trouble. The hardest parts are probably the green things that pound the ground, but there is a pattern to all of them. Upon finishing, the pad nearby will activate and you can switch to Catwoman, where you need to pick a glass case like in the second riddle.
| As with the first race, you will unlock a new AR Challenge called The Crushinator, which has you running through a single lap. The goal is to get three stars, which requires you to finish in under a minute. |
