Still Got It! (Bronze) - Hit all targets in the attic with the toy gun
During Chapter 4, you will be up in your attic, looking at some paperwork. After finishing with that, you are free to explore. On the one side of the room, you will find a toy gun that fires ping pong balls, with clips throughout the attic that replenishes its ammo. The targets you need number in four and are circular cardboard things hanging from the ceiling. If you have the auto-aim lock-on option on, then the reticle will snap to them. If you can't find them all, look in the video to see their locations. Upon hitting all four targets, the trophy will pop.
