My Friendly Neighborhood

The Conclusion is the overpowered minigun weapon that you can obtain near the end of the game. You can find 3 different film reels throughout the game, which you can put in the projectors in the projector room in the Offices. The second projector from the left is the one you want, as it will play a short video of a robber cracking a safe, showing you a code. The code is always the same though, and it's counterclockwise 7, clockwise 12, counterclockwise 4. The safe in question can be found in the Greek-themed room at the lowest level of the Studios, through the red diamond door in the same room that you obtain the wrench. Inside the safe are fuses, as well as a note giving you the order of fuses. Take them to the same fuse box you had to use previously in the basement, and put in the new fuses in this order: Spade, Star, Diamond, Heart. This will open the other metal door, and lead you to the Pirate Cove area. There's only two enemies in the area, but the pirate George is especially tanky and should be dealt with quickly. You'll find a chest in the cave on the right side of the cove, and you need to find three gems to open it. The first is in the same cave, just sitting on a box with a note next to it. The second is around the docks and at the dead-end at the back of the cove. The third is at the top of the hill, sitting on the sword plunged into the ground. Bringing all three gems to the chest will open it and give you the Conclusion.

The Conclusion has 999 ammo, but cannot be refilled. This doesn't really matter though, because at the point you obtain the weapon, the game is almost over and you realistically won't run out of ammo til the very end. Feel free to use it liberally and mow down all the obnoxious puppets in your way.
