If you are on PC you can download a mod that will let you use the harpoon gun in the game. It will replace the railway rifle when it is being used. The vault dweller’s hand doesn’t physically touch the gun when it is used in the game and bubbles come from the gun every it’s fired. This suggests that it was initially designed to be used underwater before it was cut. You can download the mod for the harpoon gun here from xxdeathknight72xx.
In other Fallout news, Bethesda has announced that they will be releasing a beta patch on steam next week to fix some of the bugs in the game.
