I've got a seriously strong Orlock gang.
Eventually we had to end up making new rules for our gangs.
My brother and I had some seriously fantastic luck rolling for wounds.Never had anyone besides some dumbassed Juves die. Most were "Impressive scars" or something like extra experience.
His Goliath gang (we used the box sets) was almost as powerful as my Orlock one, and we ripped up Ratskins, Skavvies, other gangs, and eventually whole armies of Arbites and the like.
My gang leader eventually became my Daemonhunter Inquisitor
My Orlocks had my Leader with a Meltagun and Needle pistol, a heavy with a stubber, a special with a needle sniper rifle (And a BS of 6 or something), and a ganger with a WS of 2 who won every fight he got into, armed with a chainsword.
My brothers gang had a Meltagun, a grenade launcher, a heavy stubber, and almost his entire gang had Iron Jaw, it was hilarious watching him paint them up. "Look they are all finished" <played a game> "Damn, where is the boltgun metal paint?"
Eventually the GM stopped us playing single games, and we were used as enforcers, generally being attacked or attacking 2 or more gangs.
Still got them somehwere.
