Land onto the small rooftop neighboring the communications tower, to find here a chest with a collectible in it, a generator and three pressure plates. Start by using the Shock Gloves to charge the generator. You now need to return left, quickly, and run over all of the pressure plates before they deactivate again. You may now turn and use the claw to grab onto the Datapack at a distance.
It is quite difficult to obtain this collectible. Start by positioning yourself on the pressure plate on the roof, right above the chest (the screenshot).
Turn towards the building opposite the street and glide towards that building. In the mid-flight, additionally hold down the attack button and plan the flight in such a way, so as to reach the pressure plate on the building's wall. If you have done everything properly, Batman should lean against the wall for a moment (the screenshot). For a fraction of second, release the flight button, thanks to which your character will bounce off the wall and glide towards the last one of the pressure plates. You need to behave here in the very same way as earlier, i.e. bounce off the wall properly. Land and collect the Datapack from the chest.
Locate the chest attached to the church tower, as well as a pressure plate on the ledge below. Land onto the plate and use the hook to pull yourself towards the upper part of the church's rooftop. Just as quickly, use the claw to grab onto the Datapack before the chest shuts again.
Locate the row of five button neighboring the collectible. Take a moment to learn the order in which the buttons go on, and hit the rightmost one, with the Batarang at the moment at which it activates. You may now collect the Datapack from the chest.
Datapack 9 (The Abandoned Courthouse)
You visit the Abandoned Courthouse while completing the side mission connected with Anarky, but you can go there at any moment throughout the game. Do not attempt taking through the main entrance, because it is unavailable. Instead, take the Northern entrance located at the building's back and deal with the nearby bandits, if necessary. The Datapack can be found in the main courthouse, to the right of the stairs.
Datapack 10 (The Church)
You visit the Church, among others, while completing the side mission connected with the Black Mask, but you can go there at any moment throughout the game. Deal with the nearby bandits, or walk around them, take the main entrance. Go towards the altar and find the venting shaft access shown in the above screenshot. You can find the Datapack inside the shaft.
For finding all 10 Datapacks, you receive the audio file connected with Commissioner Loeb.
