After they split up, you should be able to just follow one over behind the shipping crates for a takedown. Stick to the left of the crates and stay low, then listen to the two guards. Knock out the lone guard and drag him behind the barriers. The shipping containers will provide great cover. You should be able to just follow the left side here. Go under the raised door to reach the next area.

It shouldn’t be too difficult to run up and stun the far one, then do a takedown on the closest. Walk down and move up along the barricades to reach the two guards at the little post. Listen to Pritchard, and hop over to reach a guard that’s facing away from you. Move to the left and swing around quickly to reach the door into the main building. Move through the pipes and fry the one waiting just outside it, and then cut to the right to quickly fry the final guard at this crossroads. Then, I hide in the pipes and waited for him to approach, which led to a very quick stun gun shot. I was able to just peek out a bit and get spotted by the single guard facing into the alley. Otherwise, you’ll need to find a way to take out the three guards at the crossroads. If you can punch through walls, go up the fire escape to find a raised entrance to the building. This is where you’ll come out on the stealth path, and where you should go if you come in by any other route. The best landmark that I can give is the fire escape by a burned out car and some pipes on the ground. Whether you shoot your way in the front, or sneak in behind the front barricade, you’ll have two options to move to the concrete building that’s in your way. You’ll also get a quest note on the screen that you failed the objective, if you’re spotted. If they get a glimpse of you, but don’t actually open fire or raise an alarm, then you’re fine. Note that if you’re doing this for Cloak and Dagger, the requirement for not being spotted isn’t that brutal. Regardless, it’s actually fairly difficult to get inside without behind spotted. There should also be sewer paths too, if you’re comfortable with that. You can take this path to reach the same area that you’d drop onto. Hit the main guard, wait by the crates, and then shoot the second when he walks over to investigate. It’s easy to just tranquilize both guards. If you have the strength augmentation to carry heavy objects, you can move the crates out of your way. The second quieter choice is to look in the alley to the far left.
