First story related achievement. You start off trying to find the voice calling to you, once you meet them, you run through a few narrow streets as the game teaches you how to play. You will come to a factory that you have to run through, in order to progress through the door on the other side, you have to kill the two men inside. You will go down another few streets until there is a man at the end of the road shooting at you. You have to kill him to be able to open the bright red door behind him. After opening it and the cutscene plays, you are free to inspect the house. When you are done, there is a bed upstairs to interact with. Follow the onscreen prompts, and the achievement is yours.
