It’s hard to believe but after many, many, many delays, Replaced is finally ours to enjoy. The action-platformer set in an alternative cyberpunk dystopian 1980s America sees the story of Warren and R.E.A.C.H.. The aforementioned R.E.A.C.H. being an artificial intelligence that has unwittingly been swapped into Warren’s body. Now, trying to outrun lots of folk who want to kill him, R.E.A.C.H. must return to the lab where it all happened to try undo what has been done.
Replaced: How to Unlock the “Breaking the First Law” Achievement Guide
To unlock the “Breaking the First Law” achievement, you need to perform 50 finishers on enemies. You won’t be able to do this until you’ve unlocked the gun as a weapon in the game. This will be from Chapter 3 onwards.
Once you have the gun, when in combat, you need to build up charge before you can fire it. This is indicated by the little red gun silhouette that is in the bottom left corner of the screen. As you perform successful attacks, the meter will fill up. If you dodge, or take damage it will decrease slightly, so you need to be on the offensive (you’ll need to be to kill them anyway).

Once it’s full you can press RT (Xbox controller) to fire the gun. This is not a finisher. To perform the finisher, you need to be close to the enemy when you press RT. Reach will then perform a sequence of fancy, bad-ass manouevres, and then finish off the enemy.
Do this 50 times, and you’ll unlock the achivement.
Here’s an example of a finisher below:
