47s Hard Time [Extreme]: Predator: 3 Medals: Batman Arkham Origins

The size of this map and the number of places to hide makes this map less difficult than it seems despite a lot of armored guards with thermal headsets. Start out by stringing up the two unarmored guards. The first one on top is easy. You want to wait for the second one to move up and string him to one of the center vantage points to lure the other guards up. Then you may or may not have a double over the ledge opportunity as two guards move to the first guy you strung up. Sometimes only one guard will move to that position. 1st Medal After you climb onto the top platform engage Detective Vision and throw the sonic batarang to the nearest thug and take him out to score the first medal. 2nd Medal You can use the standard batclaw, knock over and ground pound to eliminate two of the thugs on top. If you have the batclaw disarm upgrade, you will automatically get the medal. Its important you move through the room under the glass ceiling after each takedown as that will lure the other thugs into position for the final medal. 3rd Medal Because of all the noise you made in the room earlier, the last guard should investigate directly under the glass ceiling without waiting for him to take a hostage, saving some time.
