M19 Handgun: It is found in the first room on the right as you enter the attic (Guest House 2F). It is next to a box of bullets and a first aid med bottle.

Knife: It is given by the Deputy through the window (Main House 1F). You cannot miss it.

G17 Handgun: It is found in the garage (Main House 1F) during the first Jack Boss fight. Grab the Deputy's lost gun off the ground during the battle.

Broken Handgun: Once you get outside the house, you will find a trailer. The Broken Handgun is on the bed inside the trailer. You must use a Repair Kit to fix it and get the M19 Handgun again.

M37 Shotgun and M21 Shotgun: The M37 Shotgun is a powerful weapon that can be found in the Main Hall of the the building where you meet family Baker. First, get the Scorpion Key. It is found in the cellar with the slime monsters. The key is sticking out of a piece of meat. Next, use the Scorpion Key on the recreation room upstairs (go up the stairs from the Main Hall) to find the broken shotgun inside. Then, go back downstairs to the Main Hall (Main House 1F) and take the M37 Shotgun from the soldier statue's hands and replace it with the broken shotgun to make the door behind you open so you can escape. You can also repair the broken shotgun to get the M21 Shotgun. After escaping to the Yard, look under the porch to find a removable metal part. Behind it is a box that contains a Repair Kit. Combine it with the broken shotgun to get the M21 Shotgun. It only carries two shells, but they are much more powerful than the M37 Shotgun. This weapon is very helpful for difficult areas towards the end of the game.

Burner: First, find the Burner Grip and Burner Nozzle in the Old House. The Burner Grip is found in a trash can on the deck outside the Gallery, near the bridge to the Save Room. The Burner Nozzle is found in the Water Station of the Old House. Combine both parts to create the flamethrower. This weapon is required to progress further into the Old House.

44 MAG: This powerful pistol is only available if you collect 9 Antique Coins and spend them in the Yard. The Trailer Save Room contains several bird cages with items inside. Use the Antique Coins to unlock the cage to get the 44 MAG.

Grenade Launcher: After getting the Crow Key, return to the Drawing Room on the first floor of the Main House to find the Grenade Launcher inside the supply closet.

MPM Handgun: This standard pistol is found in the lower-left office (Maintenance Room) on the first floor of the Wrecked Ship. It is easy to miss -- so go there as soon as possible.

Survival Knife: It is found on the bench, just outside the elevator doors on Wrecked Ship 2F. You must collect it if you want to survive on the Wrecked Ship for long. Note: This weapon transfers to Ethan after completing the Wrecked Ship.

P19 Machine Gun: This weapon has to be acquired by Mia on the Wrecked Ship. First, go to the second floor and enter the Lounge. There are a bunch of paintings on the wall; the ones on the left have to match the ones on the right. Complete the puzzle and grab the Corrosive from inside the safe. Then, go to the bottom part of the bunks and open the door to find the Captain's Key inside a drawer. Finally, go to the fourth floor and enter the Captain's room to find the P19 Machine Gun. Note: This weapon transfers to Ethan after completing the Wrecked Ship.
