Walkthrough - Arkham Island #8 BAA Guide

Last update: 11 May 2016

Start off by blowing up a new wall located close to your current position. After that approach the ledge and notice that new Ivy's plants have appeared in the area. There's also a new sniper here (screenshot #1). Make sure he's not looking your way and glide towards his tower. You shouldn't have problems figuring out what do next, because all you have to do is to perform a well-known silent takedown.

Eventually you'll have to return to the Botanical Gardens building located in the Arkham East district. I wouldn't recommend travelling through Arkham North, because you would have to eliminate two new snipers there. It would be possible to neutralize them, but you would only waste your precious time.

I would recommend heading towards the southern passageway to Arkham East (screenshot #1) which is going to be the well-known Abandoned Tunnel. Don't forget to destroy the plants along the way. Thankfully it'll be very easy to spot them.

Once you're inside the tunnel keep heading east and watch out for new plants. In this case you should be more careful, because some plants will be well hidden. You'll also have to use your hook several times in order to avoid large obstacles. Reaching Arkham East shouldn't take too much of your time.

Start off by destroying a nearby plant, so you won't get surprised by it later on during the game. There are two snipers in the area and you'll have to play it all out correctly if you want to avoid sustaining injuries. Use your hook to get to the first tower located to your left (screenshot #2). Don't climb over the balustrade and instead remain in a hanging position.

You'll have to wait for first of the snipers to move slightly to your right (screenshot #1), closer to your current position. Approach him quietly and perform a silent takedown. If you would decide to attack him right away you would risk being seen by his colleague. Take cover behind the left wall and zoom in the view (from cover) to locate the second sniper (screenshot #2). You must wait for him to start moving to your right before you leave this structure and move towards his tower.

Approach the second guard tower from the west. It would be a good idea to grapple up and to grab the sniper. Doing this would allow you to hang him on the rope. If you feel confident try performing a silent takedown on him. Once it's safe return to the ground level and head over to the Botanical Gardens building. Open the door to end up in the Glasshouse Entrance.
