After the credits, you find yourself back at the main menu and discover that the Riddler has shown up and scattered challenges throughout the game. From here you can replay the game again from start to finish, focusing on destructible objects and Riddler trophies, or you can jump into any scene you want, break and find what you need, then head back to the main menu to go to another without actually finishing the primary parts of the scene. The main menu shows you which Riddler Challenges need to be completed by scene, as well as how many destructible items you've broken (although not where they are).
For reference, you do not need to replay the Origin scene. There are no destructible objects in any of the Act I scenes, although The Mansion and Suit Up scenes each have 3 Riddler Trophies in them. Each of the other six scenes has three destructible objects and all of them (except for the Batcave) also has three Riddler Trophies. The Batcave has 9 Trophies in it.
There are three types of Riddler Trophies: Cubes, Hidden Question Marks, and Riddles.
- The Cubes are glowing green boxes that you have to find and pick up (usually with the Batclaw, although occasionally just with your hand). Sometimes they are out in the open, sometimes you need to do something to unlock them.
- The Hidden Question Marks can be revealed with the scanner. The large, green question marks are incomplete, missing the period at the bottom. Somewhere in the area is an object you can pick up with the green period on it (you'll often find this before you find the major part of the question mark). Take the object to where you can see the question mark and hold it up to make the ? symbol and unlock the trophy.
- The Riddles are written in hidden green ink, again revealed by the scanner. Each one will point you to some other object in the area. Scanning that object will solve the riddle. It should be noted that you can solve the riddle by scanning the object without ever finding the riddle itself.
Each time you get or solve a Riddler trophy, you are taken to a game board with a bunch of images on it of characters or symbols representing vehicles. The squares will then flip over as if this is a memory/match-pairs game and a cursor will move across them, waiting for you to choose a square. You cannot lose this. Once you choose a square you choose it permanently. When you happen to get two identical images (whether they are consecutive or just randomly at different points of progression), a new character hologram or vehicle unlocks in the Batcave.
There are also three types of destructible objects:
- Security Cameras can be destroyed by Batarangs.
- Fuseboxes can be destroyed by the Batclaw.
- Special VR Targets in the Batcave that can be destroyed by Batarangs.
Act I, Scene 2: Mansion
Riddler Trophies:
- Open the drawer of the table next to the piano to find a cube.
- Head to the large round table with a map of Gotham on it. You can rotate the table with the bar running along the outside. The cube is on the table behind a locked grate with the number 13 on it. Around the edge of the table are a number of loose buildings; each can be put in a particular location. Each also has a number of dots on the bottom. Green are positive, red are negative. You want to place buildings in spots so the score adds up to 13. To do this, place the ones with a green 9, a green 5, and a red 1. Once these are in place, press the button next to the cube to get it.
- The last location in the room has a globe. Rotate it to find the cube, which you should be able to simply grab.
Act I, Scene 3: Suit Up
Riddler Trophies:
- The first cube is sitting on a strut down and to the left. You can get it with the Batclaw once you get it.
- Once you have the scanner, there is a riddle to your right. The answer is on the left, where you can find a stray Batarang stuck in a beam. Scan it to solve the riddle.
- The second cube is on the bottom of a strut on the right (essentially in the same spot as the first one, but underneath the beam). You can see the green glow, but cannot get it until you are geared up and start the elevator to descend to the Batcave. Have your Batclaw ready and snag it as you descend.
Act II, Scene 1: Batcave
Destructibles:
The Batcave has three unique destructibles. From the forensics station, use the levers on either side of the station to manipulate the spotlight. Scanning around you will find three blue targets along the outer edges of the cave, two on the right, one on the left. After you reveal one, throw a Batarang at it to destroy it. You may also notice part of a large green question mark on the left. That is part of the first Riddler Trophy in this section...
Riddler Trophies:
The nine trophies in the Batcave are divided into three sections, with three trophies in each.
Forensics Area:
- Use the levers to the right and left of the main panel to move the spotlight around. Shine it on the cave wall to the left and up a bit. You'll see most of a giant question mark. Head to the surveillance station and grab the communicator with the green dot on the back. Head back to the forensics area and hold the communicator with the dot up to complete the question mark and unlock the trophy.
- You'll notice a Riddler cartridge by the forensic table, on the right. Put it in the panel in front of you to start a Riddler version of the VR Batarang game. Each level has a single green target you have to hit. Avoid the blue targets. You need to score over 20. Once you've done that, a Cube will be waiting for you when you exit the game.
- Use your scanner on the forensics panel to reveal a riddle. The answer is Ra's al Ghul's sword, which you can find in the evidence section (second case). Scan its hologram to solve the riddle.
Batcomputer Area:
- At the Batcomputer, turn around and scan the platform behind you to reveal a riddle. The answer is the flower on Joker's hologram.
- Bring up Robin's hologram, and turn it around to reveal the cape in the back. Use the scanner to reveal a partial question mark. One of the cartridges on the left has a green dot on it (not as obvious as with most other objects). Hold it in the right place to form the ? and unlock the trophy.
- There is a cube behind the main control panel, down below a bit (it can be hard to spot, even though it's in the open). Use the Batclaw to grab it.
Garage Area:
- In the garage section, bring up the Batplane and use the levers to rotate it around, scanning it as you go. You'll eventually reveal a riddle. The answer is the tire of the Batmobile. Bring it up and scan a tire to solve the riddle.
- With the Batmobile up, use the levers to spin it around and find a cube tucked in the back.
- Note the large green arrow toward the ceiling across from you. Go back to the Batplane. Pull out your Batclaw to get it ready. Pull the launch lever. The ceiling will open to let the plane leave, revealing a cube, and given you a few seconds to snag the cube with the Batclaw before you are taken to the next scene.
Act II, Scene 2: Dead End
Destructibles:
From the upper fire escape where you start, there is a fusebox directly across from you. The second fuse box is at the bottom, in the section to the left of Nightwing (near where the Riddler puzzle mentioned below is). The camera is on the right side of Nightwing, high on the wall.
Riddler Trophies:
- From the top of the fire escape, grab the apple next to the window (notice the green dot on it). Head to the bottom of the alley and over to the right of the main crime scene. Scan the wall back toward the crime scene to reveal a partial question mark. Hold up the apple to complete the question mark.
- Head to the other end of the alley and scan the wall to reveal a riddle. The answer is is the Iceberg Lounge, a poster of which is in the center section of the alley, on the wall opposite the body.
- Head to the middle balcony and look across from you to see three green lights/pressure plates. You have to hit all three with a Batarang in rapid succession (they will light up again after a few seconds once hit). Once all three are out at the same time, the cage with the cube will unlock. Use the Batclaw to get it.
Act II, Scene 3: Tipping Point
Destructibles:
There are two cameras and one fuse box. The first camera is straight above your head when you start. The second camera is over on a building to the left of where you start. Head to the statue to the left and look away from the Penguin. The fuse box is to the left of the doors leading into the building. You can see it from the left statue or if you turn around while interrogating the Penguin.
Riddler Trophies:
- From the statue to the right of where you start, you can turn around and use the scanner to find a riddle. The answer is the fire extinguisher.
- When interrogating the Penguin. Look down and to the right to find a cube you can get with the Batclaw.
- From the statue to the left of where you start, look away from the center area to see a cage with a cube and a series of small to large lights, that will light up in sequence, left to right. You need to hit the largest with a Batarang while it's lit to unlock the cage and release the cube.
Act III, Scene 1: Shrapnel
Destructibles:
There are two cameras and one fusebox in the morgue. All three can be seen from the starting position. The first camera is to the left above the locked evidence cabinet. The second is to the right behind and above the second body. The fusebox is on the far wall, near a closed door.
Riddler Trophies:
- When standing next to the tape recorder, there is a riddle on the wall. The answer is the heart of the anatomical model by the safe on the other side of the room, next to the safe.
- When standing by the locked cadaver drawer, turn around to look at the other side of the room and find the cube sitting in an open drawer on the other side. Get it with the Batclaw.
- Grab the clipboard with the green dot on it from the same place as just above. Head back to the first body and scan the pillar toward the center of the room to reveal a partial question mark. Use the clipboard to complete it.
Act III, Scene 2: Birdcage
Destructibles:
The three destructible objects in this area are all in the top section before you head down to Robin. This area has two cameras and one fuse box. The first camera is outside the sewer up and to the left on a sign. The fuse box is down a tunnel on the right, past the gate. When you first enter and look into it, you might see Killer Croc go by. The fuse box can be seen after he passes. The second camera is at the end of the sewer where you can look down on Robin. It is on a pillar on the left.
Riddler Trophies:
- As you head down the sewer, you'll come to a spot with a green arrow pointing up. Look in the opening above you to see a hook with a green dot on it. Use the Batclaw to get it. Continue to the end of the tunnel, but do not go down to Robin yet. Scanning to the right, you should reveal a partial question mark. Use the dot on the hook to complete it.
- From the same exact place (again don't head to Robin), notice the green arrow pointing up on the left. Directly above you are five green lights. You have to hit them with the Batarang in a particular order. If you hit one out of sequence, they reset and you have to start over (this is not timed). The order is (1) left-most, (2) second from the right, (3) second from the left, (4) right most, (5) center. Once these are hit, a cage with the cube will unlock above you.
- Head down to Robin and start the scene. When you remove the cover of the electrical panel, you can find a riddle on the inside of it. The answer is the bandage on Robin's leg.
Act III, Scene 3: Reflections
Destructibles:
There are 3 cameras in the first part of this scene. One is just off the elevator on the right, one is on the left near the first game, and the last is by the cells, to the right if facing back toward the entry hall.
Riddler Trophies:
- Head down the hallway and notice a valve on the left, with a green dot on it. Turn the wheel until the line matches the dot to unlock the cage above you and get the cube.
- Shortly past the previous one, you can find a riddle on the wall on your left. The answer is the ventriloquist dummy (Scarface) you will find in one of the cells when you get to that section.
- At the office where you hit the button to open the door, there is a clipboard with a green dot on it. Grab it and head back toward the elevator. You can find the question mark just as you leave the elevator. Use the dot to complete it.
When you break the final destructible you will unlock:
Bits & PiecesDestroy all 18 CCTV Cameras, Fuse Boxes and AR Batarang targets

When you've found all of the trophies as well, the game should be 100% complete and you will unlock the final achievement:
Knight Out100% the game. Complete the main story, find all Riddler secrets and acquire all the trophies
