Chain REaction is a miniature games rule system that makes sense. I can see using this system for 1 vs. 1 combat of 1:6 figures
Here is a good summary of the rules system
I activate and move first.
I move my figure around the corner and your
figure can see me.
You take an In Sight Reaction Test.
Maybe you shoot at me.
Maybe you don’t.
If you do shoot at me either you hit me or you
If you hit me you see how bad the damage is.
But if you miss me I take a Received Fire
Maybe I shoot back at you.
Maybe I duck back for cover.
Or maybe I runaway.
We continue to fire back and forth until either one
of us gets hit, runs out of ammo, ducks back
behind cover, or runs away.
When all my actions and all reactions that they
have caused are finished, it’s your turn to activate.
if you like SWORD and SHIELD….they have a rulesbook for that specifically
called “SWORD PLAY”
