Basically, all you need to know is that these are just the weapons that you can use as normal weapons, and you can hold the respective weapons in it and you don't need to use your modus for it. You just had light kind, which is any light-based weapon, such as a laser, and now you added Sound kind, which now you can use sound weapons, megaphones and such.
I'm just now saying you're able to use the jaw harp.
You add all of your new weapons into your strife portfolio (the weapon inventory system).
Now, what next?
Armour? Other items?
Imp bustin?
Maybe check up on the SOULLESS STRAY, maybe he has something interesting he wants to do...
So?
