How to unlock the Multi-Kill Master achievement in BINARY DOMAIN - Definitive Guide
The two easiest ways of achieving this is by attacking groups on enemies either with explosives or an upgraded shock blast from Dans Assault Rifle.
There are three good locations to do this where you get this type of kills easily on any difficulty. One is in the sewers chapter 2-5 when you face the monkey-like robots, then again when you face the zombie-like hollow children in chapter 5-3 and when you take control of the Howitzer in chapter 4-5.
I used the Howitzer method. When you first take control of it an Iron Whale transport ship comes in on the right hand side, it opens its doors and 6 assault mechs are just standing there, kill them, load the checkpoint then rinse and repeat until the achievement pops as it keeps count of all your kills. You can move forward to get a better angle and if they have managed to get out of the ship before you shoot they very kindly stand together for a few seconds.
Which ever area you choose, just use the above method.
The howitzer is also a good weapon to take out the four engines of the Iron Whale for that related achievement.
Not to be confused with double or triple kills. You get a multi-kill bonus for killing 4 enemies with a single rocket, grenade, shock burst, or melee attack. Do this 50 times. Kills are cumulative and carry over into chapter select and additional playthroughs. One good spot for this is 4-5 after you have taken control of the Howitzer. When the Iron Whale flies over aim and fire into the open hangar before the shooters have a chance to jump out. Another spot I like is when you have the steady stream of Simians in front of the elevator on 2-5. Change your shock burst to Type-G at one of the shopping terminals, and upgrade your shock burst & bosonic charge if needed. Wait until your surrounded by 4 or more Simians and fire your shock burst into them. Reload either checkpoint when you run out of enemies.
A third spot is in 4-4, after the Crab boss fight. You will get a lot of Alfies coming after you. There are several types of explosives in this room that you can use to get multi-kills if you did not use them on the boss. You can also use a sufficiently upgraded Shock Burst as they drop a lot of bosonic cells. Make sure you have already gotten your trust trophies if you are going to try this spot because trust will keep dropping when going for kills here. Reloading this checkpoint will force you to fight the boss again.
Multi-Kill is 4 or more kills at once. You may not get this on your first playthrough, but don’t worry it carries over through each play through. There are several areas that you can attempt this. Chapter 4-5 you take control of the mobile gun battery. After taking control a Iron Whale (transport plane) will come in from the the right. Simply face the hanger door that will open on the side and shoot a shot and destroy all the bots at once, you will get a multi-kill that will flash on the left side of the screen in blue. Now press start and load checkpoint and rinse and repeat until the achievement pops. In Chapter 5-4, when you fight the prototype hollow children (Zombie scrap-heads) you will come to a point where your team opens a door and you must protect them in a narrow hallway, make sure your electric burst capacity and damage, especially damage is upgraded. They will clump together, overcharge your shot and you can score multi-kills. Another method is when you are storming the building near the end of the game, you take control of the big robot with the cannons after Cain hacks into him. Iron Whales will come close to you to drop off some assault robots. Before they drop them off shoot into the side of the iron whale, the door will be open and you get a multi-kill. Killing 4 or more of them, just reload the checkpoint, rinse and repeat.
