Ta very much! I think they're a pleasing, but risky, way to screw over tough gangs...
I've just submitted a Bite-Fighter specialist to S&P, so we'll see. I've also got rules for Boing TM (done as equipment rather than a specialisation), a couple of Challenges (Pit Fght, Ambush, Mutant Animal Attack and a two-part Kidnap crime, in the manner of Bank Raid..), another specialist (Pet Enthusiast - which allows you to 'train' Mutant Animals captured in the Attack scenario) and plenty other bits and bobs. Oh - and other Justice Dept resources - holding posts, Weather Control and Electro-Cordons. Battlefield Evo - Modern Combat has got my mind straying towards other ideas, too..
Rules for Spears and for running Xemomorph / Alien / Incubi gangs are elsewhere on the forum.. though I think you've seen (and contributed to) them:

Thanks again for the enthusiastic response.
