Yes, I made a start on this in 2003/2004 IIRC when I worked in Runcorn. I went into town on my lunch break and found the Britannia Miniatures shop.On a whim I bought some SWAT miniatures and some criminals for them to oppose. After a couple more trips for reinforcements I ended up writing some rules and playing some games with club mates before putting everything into boxes and forgetting it all.
It wasn't until the Games and Gears battle boards kickstarter that I got back into it again and got everything painted properly. I now have loads of miniatures and scenery, the rules have been updated and improved but the irony is I'm still waiting for the boards which kicked the whole then off again.
