This one is required before you can start Mission 4: Carmine Falcone. You’ll work through three connected mirror rooms, each asking you to place specific objects on pedestals in the right order

How to solve the Mirror Puzzle:
There are three pedestals and a teddy bear. Place the teddy bear on the left pedestal. After solving the puzzle, the Riddler will officially introduce himself.

Looks like the first Mirror Puzzle was just a warmup. The second puzzle wants you to place a bust, a lamp, and a candlestick in this order from left to right. The candlestick is already there, but on the wrong pedestal. Let’s move it to the right first.

Remember: You can always use “Detect”.

For the lamp, just take the one from the Second Mirror Puzzle and place it onto the left pedestal of the Third Mirror Puzzle. Sneaky one!

The correct code for the building’s windows can be seen on the floor next to the Riddler Puzzle box. To start, look for the bright blue glowing power cable below the puzzle box. Destroy all green boxes to reveal a box with two target this switch sets the lights at the bottom windows. Lights 2-4 have to glow, with the first one to be out (as in the screenshot below).

Here, lights 1 and 2 have to glow; the two in the middle have to stay out. The third switch is hanging on the southern side of the puzzle’s building. Here, only the fourth light has to glow.

The puzzle box is sitting on a live power grid – touch it and you’ll fry. You’ll need to glide to a button on a suspended pillar to cut the power, then switch characters to grab the box.

This Riddler Puzzle box is trapped on an active power grid and can’t be retrieved without turning the power off.

Follow the power cable to the upper active grid. There is a pillar in the middle of it that has the off button. Since there is no grapple point on that pillar, you have to glide to it. A good starting point is the nearby “Wayne Financial Billboard”. You can also use the updraft vent down below.

While standing on the power button, switch to another character to retrieve the Riddler Puzzle Box.

A hotel sign is hiding the puzzle box. Three batteries, two generators, and one elevator ride later, you’ll knock the “O” loose and be able to grapple up to claim it.

First, there is a battery next to a dumpster on ground level. Put this battery into the elevator on the ground floor. Now the elevator is usable to reach the other two generators attached to the house. Retrieve one of the batteries from one of the two Riddler question mark signs on the roof. Then, ride the elevator two levels up to place the battery in the first generator.

Now, pick up the battery from the other Riddler question mark on the roof, ride the elevator to the next generator, and insert it. Now, ride the elevator to the top floor and leave it there. Return to the ground floor, remove the elevator’s battery, and put it back into the slot next to the dumpster. This will break the “O” from the “Hotel” sign, and you can grapple up to the elevator to pick up the Puzzle box.

Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
