While controlling Jack I can pick up weapons with the key bind to my mouse but can not drop it. I have tried different key binds and that did not work. I plugged a controller into my PC and was able to pick up and drop weapons with X.
It’s not just Horde mode. I’m having the same issue in campaign except I don’t have a controller for the work-around.
Any one know how to fix it?
To drop weapons that are picked up by his “claw”, use whatever you have bound as rotate fortification right. In my case I haven’t changed the default which is “E”. Hope this helps.
