The last part of this investigation involves a battle against some tough enemies. There will be three waves of enemies. To start, head to the area. You can go upstairs for cover, or find another spot to fight down below. This is a fast-based battle, but with powerful weapon you should do fine.
There are things you can hack in the area to make the battle easier. You can hack cameras and detonate explosives. You can also distract them. This can make it easier to bunch them up and throw an IED at them, or separate them and pick them off one by one. Your choice! After you defeat all the waves, the investigation is complete.
