When exactly is this going down? I'll have to prepare some snacks on the journey to 40k and I don't want to be late =)
I also think that we need to set out some sort of rule on who kills first, like Axis take the first turn or something. Everyone in the game pairs up with one ally and two enemies and goes to their own small section of the map. Then take turns of 10 kills and revives each before switching over. So A and B are axis, C and D are allies. A kills C. D revives C. Repeat until there are ten kills and ten revives. C then kills A. B revives A. Repeat until there are another ten kills and revives.
It is less chaotic than just killing randomly, although it will take a herculean effort to pull off.
