Walkthrough - Arkham Island #3 BAA Guide

Last update: 11 May 2016

It would be a good idea to wait for a few seconds to listen to what Joker has to say. Enemy snipers have appeared in the area and you should activate detective mode to locate them. One of the snipers is occupying a nearby tower. Ignore the laser beam, because obviously his line of sight is much bigger. Generally you'll have to try and surprise the snipers from the back or from one of the flanks. Use your hook to get to the first tower quickly.

Snipers usually move between two different spots, so you can't be too certain about what you're doing. I would recommend hiding inside the tower and waiting for the first sniper to move. Once he's stopped exit the tower and surprise him from the back. Perform a silent takedown, so he won't make too much noise.

The second guard tower is located to the east from your current position. In this case you should wait for the sniper to look the other way and approach the tower from the north-west. Use the hook to grapple up and perform a silent takedown on an armed opponent.

There are also four inmates on the ground level. I would recommend stunning the first one with a successful Glide Kick. One he's down eliminate the rest and make sure to perform successful cape attacks against the opponent armed with a knife. Once you've secured this area head east and locate a passageway leading back to Arkham East.

More thugs will appear once you reach the area where an ambulance was parked the last time you were here. You shouldn't have problems neutralizing them as long as you remember to perform counterattacks and to use your cape whenever necessary. New sniper is occupying the left tower, so you should use your hook to get to it quickly.

Just as before you should wait for the sniper to look the other way. Jump over the railing and perform a silent takedown. A second tower is located to the south and it would be a good idea to grapple up to a long metal balcony leading to it (screenshot #2). Wait for a right moment and neutralize the second sniper.

There are also two other snipers in the area and they're occupying a small roof section above the entrance to Arkham Mansion (screenshot #1). I would recommend approaching their positions from the north, however watch out, because one of them may see you. Take cover behind a large obstacle (screenshot #2) and wait for him to turn around.

Wait until it's safe and start running towards the balcony. Obviously you must use the hook to get there. There are many different ways for you to get rid of the snipers, including grabbing them while hanging on the ledge, using Batarangs or performing silent takedowns. Either way they must be neutralized before you'll be allowed to proceed with your current mission.

Drop down and use the main entrance to Arkham Mansion. I guess you won't be too surprised to find a new force field (screenshot #1). You can't enter the mansion from here, so you must head back outside. Use the hook to grapple up to the roof of this building.

Once you're standing on the roof look up and you should be able to notice a ventilation shaft. Use your newly acquired Batclaw to pull the grating and then use the hook to enter the shaft itself. You'll soon end up inside a small room. Open the door to enter Arkham Mansion. You'll find yourself standing in an area called Mansion Entrance Hall.
