GHOST 1.0

By the time you get to the biped, try to have the skills Motivation and Urgency from Ghost's Row in the skills tree. With these, the biped will have double walking speed, will take 50% less damage and will deal increased damage based on the alarm level. Try no to get the alarm too high though, if the turrets are already shooting 3 pellets per volley, it's gonna be hard to do this achievement. Don't let the tanky health of your robot fool you, it can drain quick if you don't go cautious, this corridor is savage.

Now, as you enter the corridor, use the missiles to destroy the debris and all other debris you find towards (it's a barrage of missiles, press once and it will shoot a volley of missiles). The enemies will always aim for the head so when a bullet is close, press and hold down to crouch and when the bullet is close again, let go of the down button to get back up. Unfortunately, they will shoot your head while you're crouched and as you get up, you'll have to tank the damage on the legs but you'll have dodged a lot of bullets so it's better than tank all the damage. Somewhere at the middle of the corridor, Turrets will spawn forward and behind of you, this is where you'll get the most damage because you'll have to deal with the turrets and the robots... Try dodging as much as your can while shooting, try using the missiles or that other secondary weapon that I didn't even used... If you pass the turrets then it's easier. Floating mines will start to come from behind, big robots will spawn in the front but they are slow so keep dodging and shooting. Don't forget to barrage the debris with missiles, enemies tend to stay behind the debris shooting you and your machine gun takes too long to destroy the debris. Also, when there's no enemies in the screen, start shooting on the lower left of the corner of the screen then start walking, they will spawn and you early shooting will kill them before they can even react. Oh, don't leave the biped and try to hack into another robot, they will keep shooting the biped even if you don't control it.

If they destroy the biped, you can go back some rooms by foot (like, get far away from the room you find the biped -teleporting doesn't count-) and eventually it'll respawn. Or just kill yourself. Or just "Save and Quit" before entering the room then try again... Go cautious and you can get the achievement

edit: The Motivation unlocks only after getting skills points in the Labs Zone so you can only have it unlocked in the New Game+, in your first run you'll have to cross the corridor with just Urgency skill. The Motivation Skill helps but not that much, with Urgency only is still doable but hard anyway.
