In Crime Scene Cleaner, you play as a janitor hired by the mob to clean up their dirty work. This guide will show you how to unlock the Lookin’ Out My Back Door achievement/trophy.
During Mission #10: Call in Dead"”the final mission"”you've definitely got your work cut out for you. But like the previous levels, there's a hidden area tucked away, and with it, an achievement just waiting to be found.
This time, you're on the hunt for Zack's hidden room, which is located upstairs in the control room of the warehouse.
To reach it, start by running up the conveyor belt to access the upper level. From there, jump down into the area ahead and head to the left to enter a room"”it looks like a cafeteria. From the cafeteria head to the right and pass through an office space. At the end of this room, you'll find a locked door that you'll need to hack open. Once inside, you'll be in the control room, where those keycards you've collected throughout the level will finally come in handy.
To find Zack's secret spot, look to the left of the control panel and locate a row of lockers. Place your stepladder next to them and climb on top. From there, jump onto the nearby vent, then carefully make your way over to the overhead pipes. Follow the pipes until you reach a closed grate.
Punch through the grate, crouch through the opening, and you'll drop down into Zack's secret hideaway. Doing so will unlock the Lookin' Out My Back Door achievement/trophy. To exit the room you’ll be able to leave through the door located in here.
