We do a Necromunda Campaign night every few months though it's kind of trailed off recently as a couple of the regulars have had a hard time making it to games. Generally the tables are packed with terrain though so it's a great time when we do get to play. Here's an example of two games next to each other.
I'm rather obsessed with urban terrain...
We try to keep mostly to
WYSIWYG, Most of our gangs are around 15 figs or more so there's alot of variety to play with and figs to swap out for new weapons loadouts. We've been using the Yaktribe "Necromunda Community Edition" which isn't a new edition so much as a very tightened up edit of the "Underhive/Living Rulebook" version. Very clear and well attended to and I can't recommend it highly enough.
My main gang is Van Saar
Mostly stock with 4 conversions.

I've also embarked on a project to have each of my other gangs painted by a friend of mine, usually inexchange for me making terrain for them.
The first was my Escher gang painted by a buddy who now lives in Hawaii.
All stock except for a converted Demonblade games Dominatrix.

A Delaque gang made from converted East Riding "Slicks" minis is with a friend here in Chicago
If you've got the bits and alot of patience, it's a nice cheap way to make a flavorful gang.
He's going to paint them in a scheme somewhat similar to my Scummer.

A Cawdor gang is also currently being painted by a local friend and I'm about to base and send out my last batch of characters to another. Pics of both here:

Lastly I've also got an Orlock Gang out with a buddy in Washington. He's still settling into new digs, but I hope to have them by the end of the year.
Lots of interesting proxies that still keep the general Orlock look of biker jackets and bandanas.

5 are done already and the reset will be in this general style.
I love this game. If anyone in the Chicago area wants to come by to join the campaign or just have a one-off game, drop me a line. Even if you don't have your own minis, you're welcome to run the Escher.
