The Atomic Robo comics are completely fantastic and I recommend them unreservedly.
Indeed, some people might wish I had more reservations about trying to get others into Robo. Those people are wrong!
Ahem.
Eon, if you have the core book and feel comfortable making a Weird character, by all means do so. For everybody else, we are going to use the basic character creation rules because they are 1) quick and flexible, 2) Weird character creation would take way too long and 3) I can't figure out the rules for Weird character creation (the book is rather poorly laid out in this section, sadly). If all goes well, Sam, we will make interesting original characters who aren't robots.
All you will need tomorrow is a basic character concept, a fair amount can be filled out during play.. Just keep the following in mind:
Early 1950s setting
You are an Action Scientist. You are proactive, competent and dramatic.
At this point Tesladyne is an aerospace firm still heavily dependent on military contracts but is not under the command of the US military nor what we would today consider a private military corporation. Engineering, consulting, and investigating dangerous/weird science, and being properly equipped to do these things, sure. But employees of Tesladyne are not soldiers (although of course some members are veterans).
If you work for Tesladyne, you are probably in some way an outsider. Perhaps your research expertise is...unorthodox. Maybe your family is "new money". Perhaps your political views are controversial. Regardless, there is some reason why you aren't directly working for Boeing, the US military or some Ivy League brain trust.
Action Scientist is a designation for field operatives, not a specific job description. Tesladyne employees come from a wide variety of professions, from physicist to mechanic. Rest assured, if you're a mechanic at Tesladyne, your lab is the garage and gets funding for experiments just like the guys doing Nth-dimensional math down the hall. If you're a geologist, you can expect to be sent to a volcano to do Action Geology.
