Batman: Arkham Knight

Once you get to this part in the league of assassins mission, you'll be in your batmobile and you'll want to follow the green line that appears on your minimap. It takes you to the dock area just to the northeast of Panessa Studios on Bleake Island.
Youll then have to go into the sewers. Use your line launcher to get across the water. Use explosive gel on the wall, then proceed until you see a large hole. Jump down into the hole and approach the Lazarus source and hit A. You will then have to fight off some assassins. Hit the lazarus source again and a cutscene will ensue and the acheivement is yours after it ends

Follow the path of the Lazarus particles in the batmobile to the docks (1581, 2708). Navigate the tunnels, dive to the bottom of the pit, inspect the source and then fight the small group of enemies. After the fight, inspect the source again. The achievement will pop after the short cut scene.
