Shadowrun Returns

Progress for this achievement (along with many others) carries over after loading previous saves. Because of this there's an easy way to get the achievement really early on. Start a new game and choose the rigger class, this will start you off with a decent drone.

During the first encounter you can use this drone to kill all the enemies. On your first turn go to your actions bar, tap RB, and activate "control mode" at the far right. Then simply use the drone to shoot twice and hold Y to skip everyone else's turns. Since it is a tutorial encounter you don't have to worry about dying.

Once all the enemies are dead go to the menu and select "restart level". This will put you back just before the encounter. Rinse and repeat until you have killed enough for the achievement to pop.

This can be done by either getting the required skills and a drone yourself - or by just hiring a rigger for your runs, who brings 1-2 drones along. Just check the equipped drones, before hiring. Wouldn't want pure support drones, when you want to make things dead.
Similar to the other "use X to kill Y" achievements, it helps when you soften up your targets a bit. This achievement also stacks between your characters, so no need to get sad when you don't have it once you first finished the story.
