The Evil Within I DON’T HAVE TIME FOR THIS – Achievement / Trophy Guide
In Mission 7 you are only allowed to kill the Keepers (Metal Box) that are necessary to progress in the chapter. The first one will attack you after the cutscene. Kill him and run into the room that opens up and use the valve. Ignore the keeper and run right into the next gassed room and use the valve. Kill the Keeper as soon as he spawns into your room and run to the desk to pick up valve you have to replace. Wait right here until the keeper comes to you and Freeze him with a bolt so you have enough time to turn down the gas to the exit. You won’t have enough time if you don’t freeze him. After you complete the chapter the achievement/trophy will pop.
