If you ever thought that a harpoon for underwater combat is an essential element of any post-nuclear role-playing experience worth its salt, there are both good and bad news for you. Yes, you can get a harpoon in Fallout 4, and yes, doing so will probably mess up your save files.
A Fallout 4 player who goes by the name of xxdeathknight72xx has recently found a harpoon lying around amid the unused game files. According to the player, this frightening (in more ways than one) weapon was around during the Fallout 4 Beta but then got discontinued for some reason.
Adding the weapon to the game will override your railway rifle. Judging by the reload animation that includes air bubbles coming from the harpoon, the developers intended for players to use it underwater. It may be that the harpoon was part of a quest that did not make it to the release, or possibly it could be a part of a future DLC.
A mod that adds the harpoon to the game can be downloaded here. A problem is, since there is no ammo for the harpoon to be found anywhere in the game, you will have to use console commands to replenish your ammunition. That could be an insurmountable obstacle for people playing Fallout 4 on PS4 and Xbox One: If you pardon the pun, there is no console for the consoles.
In fact, Bethesda’s VP of marketing Pete Hines was recently talking about the company’s plans to bring the mods to consoles. When asked on Twitter about the possibly to make the console available to all players, he told that “use of the console is not supported or recommended” even on PC. Answering a follow-up question, Pete Hines explained that using the console can very easily mess up your saves.
The real question, of course, is the exact extent of the risk of using the console. In Fallout 3 it was possible to mess up the saved games by using the console, but it was not at all likely. In fact, judging by subjective observations, it was far more likely that the save game file becomes corrupt on its own for no apparent reason.
Still, savvy players know this well—never rely on autosave and quicksave functions completely, because even if the saves are OK, it could always happen that you did something you are starting to regret, and there is no way to go back because all you saves got overwritten. So, it is always a good thing to save the game manually every now and then so as to be able to return to a specific point in your journey.
