its binded, my keycap is not broken, i can rebind it in game, just doesn't work. for example in game i have to press b to get out of buy and i cant get into settings to change audio stuff while in game. help

From what I can see I don’t believe Chamber is a Radiant, it seems like his “tech” comes from Astra’s powers, he’s always interested in Astra, especially her arm. Maybe his tech/“powers” come from stealing Astra’s stuff.
