It would be interesting, if we had a special ammo crossbow. Whether kinetic or energy, it would be a high impact weapon that could come with all sorts of perks. Crossbows fire bolts, which are short, stout, heavy projectiles that deliver high damage. The bolts could pierce through shields and depending on the frame could OHK on headshots. Perks like quickdraw, explosive rounds, outlaw, just to name a few could be on this weapon.
