Looking good darkscarr, nice work dude.
I was planning a custom scenario to play with my son using SWM and some of the Zombie stats people here have made. My LGS sells boxes of 30 Zombie's for $20.
Only thing is you have to put them together and paint them. My plan is to get them together and then use the paint schemes from SWM.
Maybe even customize a few mini's with the zombie parts if the scale is close enough. I hope to hit my LGS before Halloween gets here.
