I got the "olympic" colorway and mine squeaks a lot, but I think it's the tongue rubbing like how 13's fart. Stupid comfortable tho. Told my wife I might have to go grab another pair to alternate.
Fallout New Vegas is probably the best 3D fallout. Fallout 4 is a great game and easier to mod.Stay away from Fallout 76. If you want Fallout in space try The Outer Worlds. It's made by the developers of Fallout New Vegas.
