Have your cake and eat it too.
Fallout 4’s bottlecap glitch may be useful, but its usefulness is ultimately limited by the fact that the exploit involves depletion of a lot of your ammo- meaning it’s pretty useless, since even if you do end up being able to afford a lot of the best weapons in the game, you can’t really do much with them, what with you not having ammunition for them.
However, a brand new workaround, discovered by Tweaktown, apparently makes it possible for players to maximize their bottlecaps using this glitch without losing their ammo- essentially, now you can have your cake and eat it too. Since bottlecaps are definitely hard to come by in Fallout 4, this glitch should now be actually helpful- it’ll definitely enhance your enjoyment of the Commonwealth.
So yeah, go on and buy those Legendary weapons- what’s more, you can actually use them now, since you won’t lose all your ammo in the process. Huzzah!
