There are 3 achievements that are story related. You just need to play the game to unlock them.

Enter the Batcave



Identify the witness in act 2



Finish the game

Once you get to the Batcomputer in the Batcave, select a character and grab the tablet on your right.

Once you are in the batcave, you can start the Batarang trial minigame. You just need to score 30. You can do it on the original trial or on the Enigma version.

Once you arrive in the Batcave, there are two blood vials in front of you. Once of them is empty but you can fill it with your own blood. There are three more vials in a drawer on your right. You have to analyse the five blood samples to unlock the achievement. Before you can analyse them you have to put them in the centrifuge on the right.

In the Batcave, get to the case files and select the third button with the Riddler. Then select each file and put together the pieces of each item.

In the Batcave, go to the garage. Once you have selected a vehicle, you can activate the thruster by pushing the top of the trackpad on your controller (the same way you select something in the menu).

As soon as you arrive at the dead end to find Nightwing, look behind you from where you dropped. You can see the cameo. The trick is to use the grip button on your controller to zoom in.

There are four items in a fridge at the morgue. You need a key card to open the door of the fridge. You will find it inside the drawer where lies one of the victims. Once you open it with the key, look on the left and you will see the key card. Open the door and scan all four items.

When you are in the morgue, you probably noticed a lung on a table. Grab it and bring to the head next to the safe. You will find the other lung next to it and the missing eye is above the safe. Put all the pieces together and the achievement is yours.

There are three AR targets in the batcave. Use the two levers in the forensic area to locate them and destroy them with your batarang.
At the dead end you have to find 2 fuse boxes and CCTV.
At the tipping point, in the morgue and when you go rescue Robin, you have to destroy 2 cameras and 1 fuse box to destroy.
In the last level, there are 3 cameras to destroy.
The CCTV cameras and the fuse boxes are usually easy to spot with their red lights.

That is the hardest achievement for sure. In order to help you, you can go to the main menu to learn what you have left to discover in each part of the game.


This logo means you are looking for a mystery cube somewhere in the environment.


This means you have to put together a green dot and its question mark.


When you see this, you have to scan the area to find a riddle and then scan the object which is the solution to the riddle.

I am quite sure you have to finish the game once before you can look for all the cubes.
I won't write here all the solutions but you can write a comment if you can't solve a riddle or find a trophy.
