So I'm planning on running this for my home group, but there are a few things that don't quite make sense about it to me that I think I'm going to change.
First of all I'm going to give team a bit more prep time (about an hour). They aren't going start at the top of the building, but MacCallister will have made the arrangements to have the building security bribed so that they can make use of it. I'm also assuming that MacCallister and Parker have been in contact and made some plans. I'm going to have MacCallister have a guy nearby with the climbing gear in a vehicle that he can hand off to the runners, instead of just having it sitting at the top of the building.
I'm also thinking about not making it a "hostile extraction." That seems like a stupid and pointless thing for Parker to do. If he does this then the runners may well keep him sedated, in which case it would be pretty hard for him to secretly try and broker a deal with a foundation. I was thinking of instead having Scion say that Parker and the foundation have been in contact and that Parker is interested in leaving (even though he just got hired- he didn't want to work for Horizon in the first place, but he was happy to have them pay for his education). I'm not sure if this is a good move though. Thoughts?
