Here's my problem: I've got a group of runners in the arcology. STill 2060 in game, but using the 4th edition rules. They have an idea on how to escape. They're going to the 4th story, blowing some floor to ceiling windows, and driving down on motorcycles to the I-5 on ramp. They already have a plan to blow up the mines before they get there, so their landing is going to have arough landing.
But I have idea what to use for threshold or modifiers. I think max threshhold for extremely difficult is 4-5. I'm thinking modifier of something like -6 for going at an extreme angle very fast. It says to use the highest modifier only, but really I just pulled that number out of my butt. They need some sort of way to make the bikes point up again (instead of at a 45 degree angle), thinking perhaps a strong barrier to make a ramp.
Ideas for #'s please? Luckily everyone in the group has at least a 5 bike and high reaction and edge.
