Everyone can hate me later but sometimes there are game breaking button glitches TOO easy to preform. Hopefully this gets attention because a patch should address this issue.
Basically you can fast relaod with a boltshot by charging it and IMMEDIATELY after you hit reload and the animation will cancel. This enables you to unleash another charged bolt causing an already cheap weapon to be even cheaper.
Heres a video tutorial on how do this and a Thruster Pack Tactic, I take no credit for the video.
Enjoy it while it lasts!
