If you're still interested, however, here's a video that demonstrates the glitch for you.
The glitch takes place when you are interacting with the vendor selling all one type of ammunition will then provide you with the ability to increase your bottle tops infinity. Apparently the glitch also works with other types of ammo.
Buy one type of ammo, and only one type. You can then sell this round until you drain the vendor out of bottle caps. Meaning you can get all the bottle caps and all the stuff you could need.
Anyway, bottle caps is where its at in Fallout 4. Otherwise it functions pretty much the same, though I doubt you'll have much luck trying to get infinite money out of your local Best Buy customer service. This should leave you with one.
However, as GameZone points out, the glitch will not actually get you unlimited currency. If you're comfortable with that trade-off, though, go right ahead and use the exploit. Use this one while it lasts, as Bethsoft is bound to completely patch the glitch...especially since everyone's writing about it.
As usual, a word of warning: You're free to do this, but it may take a few of the fun out of your nuclear sails. You can find the full list of cheats for PC here.
Fallout 4 has only been out for two days now, but gamers are busily deconstructing its layered surfaces and cataloging exploits.
