How to unlock the Snakebite achievement in Wolfenstein II: The New Colossus - Definitive Guide
1) After you pick up the Constrictor Harness in Manhattan Nuclear Bunker there is a good spot to obtain this achievement. For the Übercommander you have to enter a small pipe, left side of this hole is a train waggon, go under there and crawl forward and you will see the legs of the Übercommander and from a soldier, now wait that one of them are close enough to you and then push the melee attack button
2) Another place without playing a whole district is at the beginning of the New Orleans Confinement Wall District. Go left side in first hole after you leaving the hole you see on your left side a train waggon. Shoot in front of this train waggon to get the attention of the enemies here and crawl under the train waggon and wait for some enemies that they come close to you and then hit the melee attack button.
Towards the end of the mission, you'll come to an area with an Übercommander that can only be accessed using a floor grate (there will also be another soldier in there with him). Go into the grate and come out where they can't immediately see you. I'd recommend making a save point right here. Fire an unsilenced weapon at the ground, then get back in the vent. The soldier will walk over to where you were and you can easily take him down with . The achievement should pop right there, but if you want to get a few more to max out the perk, reload the save point and do that four more times.
Here's a clip of me doing this to demonstrate:
Hopefully this helps some people. If you see a mistake or have something to add, let me know and I'll edit (don't just downvote with no comment, that doesn't help anyone).
This achievement is best done post-story.
After obtaining the Constrictor contraption (either through the story or by finding it in the Nuclear Bunker district of Manhattan), there are two spots to easily get this done.
The first is during the Wall district of New Orleans. After infiltrating the Wall, make your way to the lowest level without causing any alarm. Here, there are two enemies on patrol; one is walking back and forth through a large, red-lit tunnel, and the second is standing still in front of a cart of boxes. Do whatever you can to eliminate the mobile guard stealthily. Once that is done, pass through the tunnel and exit so that you are behind the cart of boxes. Now crouch in front of the cart and move forward. This will cause BJ to squeeze underneath. Crawl forward and when the melee/execution button prompt appears on-screen, click it to perform a Constrictor Harness takedown.
The second place to get this done, which is actually right after you pick up the Constrictor contraption if you didn't choose it as part of the story, is during the Übercommander assassination mission in the Manhattan - Nuclear Bunker. Towards the end of this mission, you will need to crawl through a floor grate in order to reach the room with the Übercommander. Go into the grate and peak your head out of the exit. Make a manual save here, fire an unsilenced weapon at the ground, and then crawl back into the grate. This will cause the soldier guarding the Übercommander to come forth and inspect the noise. When he is close, perform the Constrictor Harness takedown to unlock the achievement.
