Alright, updated the OP with what I've been thinking so far.
This is gonna be a relatively short mission. It lowers the chance of RP death, and if we wanna cary on, it's as simple as going on a second job (with new people if they wanna join).
A typical Shadowrun follows four phases: getting the job, planning the mission, the mission itself, getting paid. I think that might be a good idea to follow. Gives us some variety, lets the players plan a heist (come on, you know you've always wanted to!), and it ensures we won't be stuck in a single scene for too long.
I really don't wanna railroad this thing (although I'm definitely gonna end up doing it anyway, so feel free to call me out!). So I was thinking, while I'm probably gonna be establishing a few things in a scene, so I thought we could use the good ol' "if it's posted, it's canon". If you write that your character spots a guy on the roof, there's a guy on the roof.
We'll figure out the actual mission once we've got our players ready in the OOC, as it depends on the players. If nobody wants to be a hacker (althought I doubt that, you get to hack computers with your mind), I'm not gonna send people on a dataheist.
