Easy to learn rules with nice solutions to deter wargamers acting like wargamers.
In FFofL a man's gotta do wot a man's gotta do, and that means doing it out in the open on main street! But there's always one who'll shoot yer first and then scuttle into cover, like a low down rat, up a drainpipe. Try it in FFofL and you get an automatic scatter gun blast, from the owner, on entering their premises.
Simple and elegant way of deterring skulking about and backshooting!
