A Happy Place
Last Updated: 9/6/2017
This easter egg is found in the Hideout, accessible through the "Mission" menu.
After gaining access to the Hideout, head to the shooting range with a gun and shoot the trash can that is very close to you on the left side of the window.
After shooting the trash can, turn around and you’ll notice that 4 rats are starting to form a line on the floor. Shooting all of the rats will display a message that says, “You sent all the rats to a happy place in (insert your time)”.
