Once you've suited up, you'll start trying to hack a signal. You can listen to either of the Green nodes for information and flavor audio but you want to use the sticks to navigate your cursor to the yellow circle. Once you're there, hold the A button to decrypt the signal and listen in.
Once you've listened to the message, turn back towards the ladder you came up and in the distance you should see what looks like a courthouse, as well it should. Make your way along the rooftops until you get close. Hold the A button and run off of one of the buildings to glide. If you are close enough to the enemies in front of the building, you should see a little blue Bat symbol above their head. This is your target and you can change it by adjusting your gliding. Once you've picked an enemy, hit the strike button to glide kick into them, starting a fight.
These enemies may have bats but that doesn't change them too much. It really only means you should be careful to counter them when they attack because their attacks do extra damage and may daze you a bit. If you manage to get your combo counter high enough then you should be prompted to use a takedown move by hitting two buttons. Do so to instantly take one of the enemies out of the fight. Remember to keep the combo meter going so you can get more takedown chances. Once you've eliminated them, move inside. Yes, through the front door.
