How to unlock the One-Shot Master achievement in BINARY DOMAIN - Definitive Guide
Also during campaign you will get attacked by little spider robots. Once you kill those you will always get one shot bonus.
Best to head to Chapter 3 where you're trying to reach the rooftops and rinse the tiny electric leech type robots.
Be sure to roll or melee if they attach to you .
Hope This Helps :)
As the name suggests you get this medal when you kill an enemy with a single bullet of anything. Melee doesn’t count, this would probably be easier on lower difficulties but since we are playing on survivor this might prove difficult. The best way to go about this is the little electric leech robots. You first encounter them in Chapter 3 when you are trying to reach the rooftop. They are annoying but are easy to kill, if they ever get on you make sure to melee.
Kill 50 enemies with one shot each. Recommend using Jugland R93 or Yamato 50 Sniper Rifles, the RAOW-SR1 Sniper Rifle is usually too weak for this. Also, you can use any gun to kill Watchers (Surveillance Bots) or Needle Bugs. It's possible to get (3) one-shot bonuses from each Surveillance Bot since they can split apart. Another method is to use the turret to shoot down the Condor Drones that the Iron Raptor launches in 2-4. Kills are cumulative and carry over into chapter select and additional playthroughs.
