1 Ishmael: All right. We have a map of Horsell Common, as the staging ground for the initial Martian invasion.
2 Ishmael: The Martians attempt to land attacking cylinders there.
3 Ishmael: We need a game mechanic to simulate the chances of the cylinders successfully coming from Mars.
4 Martian 1: Roll 6d10, and if all the dice come up zero they make it.

Thanks to a friend for the inspiration for this one. I asked what would be a good game mechanic to simulate Martians landing on Earth? This was his answer, and it was so perfect the strip wrote itself.
