43s Wrecking Crew [Extreme]: Bruce Wayne Predator: 3 Medals: Initiation DLC - Batman Arkham Origins

These final two maps with mostly armored guys are especially difficult for this character as there is no fast way to knock them down or disarm them. You need to rely on ledges and grates for faster takedowns. 1st and 2nd Medals Start with grappling around and pounce the unarmored guy on the far side for the first medal. You want to Shuriken the extinguisher before knocking him out to avoid getting shot at. Then you can use the grate to takedown the armored guy in the smoke for the second medal. The remaining two unarmored guys should come running to your position. Disappear with the Kujiki bomb and you can do a double takedown. The smoke will clear and you will be spotted. Quickly disappear again and jump away. I actually meant to jump across and hang on the opposite platform where you can get a good view of the oncoming enemies since the jammer guy is still active. Once they come close to the railing, you can grapple on and should be able to perform a double ledge takedown. 3rd Medal Make sure the remaining guys spot you or they wont jump down. Drop the smoke grenade once they are close to the weak wall. If they are not close enough, you can use a redirect, shuriken or stun to get them closer and they should not move again while inside the smoke, giving you enough time to go around for the takedown. To make things easier, you can instead toss a smoke grenade into the oncoming crowd and pull them down. However, for some strange reason, double over the ledge takedowns dont work well in the smoke and you have to move to a different spot to pull down another guy. If all else fails, you can always grate takedown. Then you can lure the last guy down to the weak wall and ultra stun him in front of it and wait for him to get up. The riskiest approach is not to use the Kujiki bomb at all and try to lure everyone down near the weak wall. Drop a smoke pellet as soon as someone gets in front of the wall and then go around for the takedown.
