Walkthrough - Caves #2 - part 5 BAA Guide
Last update: 11 May 2016
Either way you'll have to be extremely careful during the fight. Don't forget to use cape attacks against more experienced thugs and prevent other inmates from picking up the assault rifle. You'll also have to watch out active pumps on both sides of the room, because coming in contact with them can have serious consequences.
Look around once you've been able to defeat all the hostiles. There are two control panels nearby and you'll have to use a sequencer to shut them down. You may now return to the upper balcony and open the door leading back to Pressure Control Junction. Head forward.
Once you've reached the central area you'll find out that you've been trapped by Joker and that you'll have to defeat his allies to proceed with the mission. Your objective will be to defend yourself against waves of enemy attacks and aside from the standard inmates you'll also be dealing with a new mutant.
Make sure to use the same tactics as before, so you'll have to move away from the beast and wait for it to start running towards Batman. Throw a Batarang at the creature followed by an evasive maneuver. Approach the stunned beast and throw a few punches for additional injuries. It's also a good idea to encourage the mutant to hit one of the electrified barriers instead of a standard wall.
Once you've stunned the beast once or twice the monster will kneel down, giving you an opportunity to hop on its back. Notice that new inmates have arrived in the arena and it would be a good idea to attack them before you'll be forced to get off.
Sooner or later you'll have to start attacking the inmates on your own. During this battle watch out for the mutant, dodging its attacks whenever necessary. You can also ignore the thugs entirely and just run around the room in hopes that you'll be able to ride the beast again or that the mutant will harm enemies without your assistance.
Next phases of this battle are going to be very similar to the first one. Each time when you'll find your way to the monster's back you'll be attacked by a new group of inmates. Defeat the creature only if you've already dealt with other enemies. Doing this will allow you to move on with your current assignment.
Proceed towards the northern corridor and look up with detective mode turned on. You should notice a weak section of the wall and you'll have to get rid of it using your Ultra Batclaw. Grapple up to the new platform, turn around and use the Ultra Batclaw for the second time. Ripping off the second weak wall will allow you to proceed to the top.
You'll have to make a jump towards a smaller platform from here. Choose the Explosive Gel from your inventory and plant the charge on the weak section of the floor. Once this is done return to the previous platform and detonate the charge. You may now witness a cool cut-scene.
Look up again and use your Ultra Batclaw for the last time in this area. Once you've destroyed this section of the wall grapple up to a new platform and head forward. You'll soon find a door leading back to Arkham West.
