The Surge 2

Just wanted to add that if you don't get this one on the first Checkpoint, that there are at least 2 more in the game where you can get this cheevo.
Theres a path to disable them without sounding Alarm on every one of them, usually from the tops of containers or roofs.

Yeah, this is odd … I had used almost this same path but didn't get the achievement. Rather than jump down where he did, I used my turret to kill the other floating "eyebot" further up the street, dropped down there (undetected), and came back up without being seen to this port/terminal. After disabling the station from that terminal, alarms went off and I was attacked by the wandering guy. Not sure what I did wrong.

I just did this, there is a patrolling unit to watch out for, he has a 4 maybe 5 point patrol. Waiting for him to walk towards the gravity lift seems to work.

If you find yourself in a medbay next to a room full of rubble, water, poison and nanites,

This didn’t work for me. But maybe it didnt because I had already triggered this spot much earlier in the game. Even loading out into a different zone and reloading back in and trying. Nothing. 🤷🏻‍♂️ But managed to snag it on the next AID Gateway with stealthy skills learned in Assassin’s Creed 😉

I got it first try in NG+.

I did the same thing on the very first gate, once you’ve triggered a gate even once, then it won’t work for the achievement.

An alternate way but still very similar way to get this is to just fall down to the truck first (they still won't see you) and wait till the wandering guy is walking away.

If you mess it up, be sure to quit to xbox menu then load the game and revert the save to the last med bay visited and try again.

The route worked for me! It did take a couple of tries, however.

To add onto this, there is a 3rd scanner in the A.I.D. Command section in the game maybe a little less than halfway into the game. This is a really easy one as well. Just make sure to have 5 grenade charges for your drone, as you will need to take out 1 A.I.D. guard once you go up the grav-lift (you'll know everything I'm referring to once you start exploring the A.I.D. Command area). Kill that guard with the 5 grenade drone charges which should be enough, then hop down once the 3 legged robot goes the other way and take out the scanner.

I was worried I'd have to go through and mop this up on NG+ since I don't see the 3rd scanner mentioned at all but there definitely is one if you managed to walk through the 1st 2 and set off the alarm like I did before I knew.

*edit*

Adding onto this as there is an even easier 4th checkpoint after the 3rd mentioned above in the A.I.D. Command area. You'll come to a 4th checkpoint in this area where there will be 1 enemy on the ground floor you can take out. Right next to them are stairs going up the metal A.I.D. sctructure where you'll see a partially opened metal door you'll have to hitX to pry open like you've done many times already throughout the game. once opened, you'll have to deal with another guard and then pry open 1 more door. Inside this door is a chest and above it, the thing you need to fry with your drone to disable the gate. This is by far the easier if you messed up the early game checkpoints.
