Unlock the Handcannon
When you unlock Fourth Survivor, and play through it, there is a secret room located in the police station lobby next to the front doors. When you walk past this room, HUNK will face the doors leading into it for a moment. Shoot the doors and they will open, taking you to the secret room. Inside is the handcannon on a desk at the left of the room.
To be able to upgrade a weapon to level 5 for unlimited ammo get an "S" rank in all the missions on Hard.
