Gonryu? pff. Check out the Fleche Armaments XM-407, I'm almost set on arming the majority of my QRT Helicopters with it. As far as regular grenade launchers go, load them with splash grenades and armour debonder, rampaging troll with arcane arrestor and a million billions armours? No more! .
But, how do bursts with grenade launchers work? do you apply each of the explosions separately and roll for scatter or just the regular rules for full auto and you only apply the grenade once?
Unfortunately Chummer won't let me load either the 407 or the rest of the launchers with ammo...
