Sonic shotgun can be special weapon (that can blast any player from you, as in virus originally). It could damage players, if they got blasted to a wall and such.
I honestly don’t know why it is still not in the gameworld, it has icon, it has working ammo and only can be spawned as pickup right now (0.17.7.0). It can perfectly fit to the gameworld.
Also would like to see sonic shotgun gametype where everyone only can blast each other with alt fire of it.
