I got an ork to level 6. Opened all the boxes, didn't get a mag mod for the big shoota, but in game, I have seen guys with drum mags on big shootas, and also what looks like an extended mag, and no I'm not taking about a regular shoota or a tracey shoota, I ain't a grot who can't tell. What gives? Did it get taken out 'cept for them what already had it? Is it some kinda special big shoota that was limited time or something?
