Would anyone be able to make a change to the laser weapons charging sound? You know how when you flip the little switch and it hums on? Replace that with the GB proton pack power up sound. I've looked and someone made one before but Nexus took it down for "copyright infringement" and they hadn't put it up anywhere else. That's the one someone made, minus the actual firing sound and effects I just want the sound when he turns the rifle on. If anyone could do this that'd be great!
