Alien: Isolation

Maintenance jack is used automatically when you press

Can be done right at the beginning of Mission 4. Walk down the hallway until you see an android that's facing to the right. The first time you can even run up to him and hit him quickly, but the next few times he seems to be more aware.

Hit him twice and immediately step back so he doesn't grab you. Run back to the beginning of the Mission and wait for a few seconds. Take your time and walk back. He will be standing in the same are and you can hit him again. On easy he takes 7 hits, so you have to repeat this 3 more times.

Start up mission 4 and walk around past the reception and continue down the walkway you'll come across an Android with he's back to you slowly walk up to him and use twice and then turn and run away back to the start thus losing him. Once back at the start start making your way back to him and creep up on him and do the same as before then return back to the start and do this one final time and he will die netting you the achievement.

Just be very careful after you return to him because if you run or walk up to him he probably will turn around and chase you.

Maka91 offered me he's video to show how its done so thank him.

I realize there's already a few guides up but here's my video contribution.

This details how to get three achievements at once (including My Turn Now) for the first android encounter of the game.

I use some extra features such as the air filtration to disrupt the android's vision, and detail exactly where to go/what to do.

(Note: I did this on Normal mode, so your results may vary depending on difficulty).

Hope it helps!

I would like to add that you can get this without using the Maintenance Jack at all. I was using the Bolt gun to make headshots on the Androids that spawn behind you when you Overload the Beta Core to activate the Purge (Mission 14)

I remembered getting it this way on the 360 version as well. So you don't need to go out of your way or care that much on your first playthrough.

Ever wondered if the smokebombs have any use? They actually do. Aside from being the only item that only cause the Alien to drop, but not investigate it also allows you to sniff Alien or Android booty completely unharmed.

Load up M12 and sprint all the way through the level until you reach the point where you have to turn on 3 generators.
After you turn on the one in the middle an Android behind you will spawn/stand up, plant a smokebomb before doing so and craft a 3rd one. Turn on generator, turn around and wack the Android twice.
Take a few steps back, toss smoke and wack him again.

Any mission after getting the smoke is fine obviously, but chances are the Alien is around.
