What is the deal with this stupid weapon? Is it just me or does nobody know exactly what the secondary fire for this gun does. When I use the seconday fire I see bullets bouncing all over the place but I'm still not sure what it does.
Any rivets already fired and sitting around (either in enemies or on the ground) immediately start firing again in random directions and ricochet off surfaces. Essentially gives your rivets a second chance of damage after being fired normally.
It's a horrible gun. I would rather melee my way through the game, than use that gun.
