This is a very old two player strategy game known variously as Hare and Hounds, the French Military Game and several other names and brought slap bang up to date with a theme which relates to the ever-present fear of the ZA.
I first came across hare and hounds when reading through Martin Gardner's Mathematical Games column in an old copy of Scientific American. If you play it you'll find there's a lot more strategy to the game than first meets the eye - rules of play in the next step. And you never know, come the Apocalypse it may even save your life!
This game could be played on a board drawn on a piece of paper and four counters, but I've got a 3D printer so I thought I'd make a more tactile version. Another factor was I'd vaguely promised a young friend some sort of 3D printed present. I thought this take on the game would be perfect as she's keen on Zombicide.
