Had these for a while now, finally getting around to painting them! These are the damaged urban tiles, I was originally going to be getting the rolling fields, but I changed to these at the last minute because they're perfect for building an arena for my game Mechadrome. I'll also be using Mantic's ruined battlezones for terrain for that same purpose.
Here's a couple of pics, you can click for the bigger dakka gallery versions.
Here's my recipe:
I started with a generic gray spray primer I got from Home Depot as a base coat. It's almost the same color as the original plastic. I paint in most of the cracks on the street with brown paint, I think it Vallejo Earth or something like that. I used the same color for the base color for the dirt piles.
I was going to mask off the sidewalks and use black spray primer for the streets, but I have a few extra bottles of Vallejo black, since I kept forgetting I bought some and ended up buying a new bottle 2 more times over the last 9 or so months (old age sucks). So I'm just drybrushing the black over the street parts. Since the Vallejo black is kind of glossy, I had to spray it with matte varnish at the end. I'll probably do a 2nd or 3rd coat too since I'll be rolling dice and moving minis on it.
For the sidewalks, I'm just going with the gray prime, which I washed with my own wash that's about 50% water, 25% matte medium (you can get that in any art store) and a mix of black and a little brown mixed in. After the wash dries, I drubrushed vallejo wolf gray over it for the lighter color and to pick out the details better. I also washed the dirt piles and drubrushed those with bleached bone.
For the manhole covers, I did a base coat of a reddish brown mix, then I added blood red splotches and orange splotches, then some gunmetal drybrushing for highlights and a wash with the same wash.
Sounds like a lot of steps, but it's pretty easy and there's lots of detail for drybrushing which is how I paint pretty much everything anyway.
