With a new Necromunda campaign due to start in about 2 weeks, I've had to acknowledge that I won't have time to get the Helmawr gang finished in time. They'll just have to sit on ice for a while, and instead I can add a handful of new figures to the Venators. I've worked out that with the Venator ogryn, I only really need another 3 figures to have a viable gang with plenty of options.
One of my favourite specialists in any gang is the long ranged shooter - that guy armed with the high powered rifle and a selection of scopes who can pick of opposing fighters at range.
