Hope you have fun with it, it was a very radical set of rules and need an imaginative umpire but we thoroughly enjoyed it.
Has anyone here ever done this? How did you do it? Any tips?
Thanks!
I’ve done a similar game in the past which was set in 1940 and required downed German aircrew to evade Home Guard patrols and get to a phone box to call up a 5th Columnist. The table was set up with plenty of cover and players told me what they wanted to do, I marked their moves on a rough map, told them what they could see or hear and where necessary, put figures on the table as the various parties saw each other - and removed them as they hid or ran for cover. It worked well and we even ran it as a participation game at Bovington one year (although given that figures rarely appeared on the table it may not have been the most thrilling game to watch

).
A couple of thoughts:
1 keep the rules very simple and in the umpires head - I ran it on a percentage chance to hit based on what I thought the odds were.
2 get the players to explain their thinking - one chap in the participation game asked if the Home Guard were trained or whether they were likely to panic on hearing a shot. He then fired a random pistol shot as they crossed open ground towards his hiding place and made successful rolls to have them all dive for cover while he ran into new cover.
3 wider access to digital photography would make it easier to allow players to show the umpire secretly where they wanted to move to/do. I suspect adding sound effects from the iPad might also add to the general confusion.
