Oh. Probably the big shoota and the deff guns. Speaking of which, have they mentioned if Flash Gitz are going to be a veteran class or is your "Flash git" just a shoota boy with a proper flashy gun?
Flash Gitz have a special weapon, the Snazzgun. I don't know if they're going to be an elite class though, have those been listed for the Orks anywhere? Lexicanum Link here described as a "high-calibre, full-auto weapon", so I think the generic image is a heavy bolter or auto-cannon cousin. Within the family there are three varieties- one with higher rate of fire, one with greater damage per shot, and an energy variant akin to a plasma weapon. Whatever the case, they offer significant firepower and considerable noise. Actually, those three variations sound like a decent guess for the first round of Slugga modifications, presuming the other races have plasma-pistol equivalents by then.
Isn't the Big Shoota more the equiv of a heavy bolter? Or is it a step between a bolter equiv and a heavy bolter.
The big shoota is more like a LMG for the orks, where a Snazzgun is more like a HMG. To be fair a big shoota in most of warhammer games is just like a better rifle and sometimes with small supresion bonuses. The snazzgun is directly the heavy bolter counterpart of the orks. So yeah, big shoota is something between bolter and heavy bolter (or combi bolter to heavy bolter, dunno, compare what you like most)
So whats the big over the shoulder gun with the two barrels. That's a deff gun isn't it? Whats the difference twixt a deff and snazz gun?
Well, you could say that deffguns are actually for lootas and snazzgun are a thing for the flashgitz. But to be fair I don´t know what´s the big difference between them. Both can be modified and both can use from bullets to laser rounds.
