They'd probably be better off asking the Ork fanbase (That means you guys) to come up with Ork guns (Concept, look, etc), or maybe even making an in-game/in-engine gun maker (Kinda like Loadout, where you could change all the pieces on your gun and select how it shot etc) Just my opinion.
'Ere's wot I tink boyz. Owr gunz shuld be rite Orky soz dat meanz bigga an' bettah! Sluggaz shuld be 'uge! Dubble erryting da 'umiez got fer der pistols. Mor bulletz, mor damage, an' o' corz LOWDA! Dem Boltahz da 'umiez got shuld be bettah den a Slugga doe since itz juz a pistol. Owr Shootaz shuld be just like dat Stormy Bolter! LOTZ O' BULLETZ!!! DAKKA DAKKA DAKKA!!!! Biggah Shootaz culd be kinda like a 'eavy Bolter but since wez biggah we can run round wiff em. Dey don't suppress doe and still take a bit to fyre! Iff yuz guyz arr worryed bout long range.... WUT ARR YA PANZIEZ??? GET IN DA FITE! WAAAAAAAAAGH!!!!!!
I had suggested something like this awhile back and was told that it would probably require too many resources to implement and detract from other aspects of the game.
I don't think any ork weapons are accurate. They used to have gretchin snipers, but I think they got rid of those?
I didn't mean an accurate one just something effective at range. Like something with a random fire pattern about the size of a marine but massive rate of fire and range. Example: the anarchy in borderlands will fill the space of its reticle with bullets resulting in a big circle of bullet strike decals. The shots don't really go outside the reticle but it is a big reticle. I'm hoping for a gun that 25% of the shots fired go where i want but has a rof of like 150 rpm.
