Walkthrough - Arkham Mansion - part 1 BAA Guide

Last update: 11 May 2016

You'll find yourself standing above e very large room that's being guarded by three thugs. Take your time to locate the only inmate armed with a gun and use the Glide Kick ability to stun him. Once he's down take care of the remaining two before he gets up and picks up his weapon. Eliminating him as well will allow you to secure this area.

Look up and focus on finding a small edge. Use your hook to grapple up to that platform. Once you've found your way to the top find a grating and use your Batclaw to get rid of it. You may now use your hook to find your way inside the ventilation shaft. Eventually you should be able to reach the Main Hall.

Head down and you should end up standing above a large hall. There's a group of inmates beneath you and you'll have to attack them. Use the Glide Kick ability to stun one of the enemies and then take care of the rest. This is going to be a challenging battle, so don't forget to rely on counters and cape attacks.

Head north once you've eliminated all hostile units. Use the stairs to reach an upper section and then proceed through the left door to end up in the West Wing Corridor. Press the crouch key upon your arrival in this new area. Head forward and perform a silent takedown on one of the inmates who was holding hostage some friendly guards.

Familiarize yourself with the info on how the collars work and notice that a new upgrade called Sonic Batarang has been unlocked (you still have to purchase it if you're interested). Once you're ready proceed through the door located in front of you and you'll end up in the Arkham Records Room. Use your hook to immediately grapple up to the nearest gargoyle.

There are a couple of armed thugs in the room and you'll have to eliminate them one by one. It would be a good idea to use other moves aside from the Glide Kick ability. The newly unlocked Sonic Batarang is an interesting gadget when you want to distract enemy units and you should also consider acquiring Inverted Takedown ability (screenshot #2). Bear in mind that the collars have alarms, so you'll have to move away each time to avoid detection.

Obviously your objective here is to eliminate all the inmates without receiving any major injuries. Once it's safe leave the gargoyles and inspect the central area to find the hostages. All you have to do is to press the action key and Batman will automatically free them. Listen to their statements and then proceed through the northern door to the North Corridor.

Keep heading north and locate the stairs to reach your current destination. Eventually you'll have to find a new ventilation shaft. Use the shaft to travel to a new location. Find the second shaft in the north-west which will be located near the ceiling (screenshot #2).

Walk through the second shaft and once you're inside a larger room with a lot of pillars proceed to your left. The final third ventilation shaft is located near the floor. Use the tunnel to reach Dr. Young's Office and don't forget to listen to an interesting conversation along the way. Head down and approach three thugs stationed outside of doctor Young's room.

Land on the ground without making too much noise and approach the inmates. One of them is standing a little further away from the door and he'll be using a gun, so eliminating him should be your top priority. Once he's gone focus on his colleagues. Head on to your right when it's safe and use your Batclaw on a nearby grating. Doing this will gain access to a new ventilation shaft.
