I've spoken recently to Tony of Wargames Factory (makers of the new multi-part zombies). I ran the across him the idea of a multi-part modern human sprue including civilians, a few firefighters, some cops, etc... in short, a sprue for the Enclave.
I picked up a few of their zombie packs and must say, Im impressed. At roughly $.75 per zombie, its a nice, cheap avenue to filling out massive hordes of brainmongers.
Tony is also one heck of a guy. We chatted for a bit throughout Cold Wars and he's certainly got my business. Wargames Factory is based out of Massachussets. Since we're based out of Connecticut, I think some collaboration is possible.
If you haven't stopped by their website yet, they have a neat program called the Liberty and Union League. Its one heck of a marketing strategy as well. Anyone can register and suggest sprues. If they get 1000 people expressing interest and "pre-ordering" (no payment required up front), they'll spin up the dollies!! Perhaps we can start a movement to create Enclave sprues.
