For ACUS, characters will be based on 50 points. If I don't get a character from you before the con, I will assign you a pre-generated character based on 30 points.
I'm generally assuming that PCs will take one or more Drawbacks as explained in the game rules, so a PC with no Drawbacks at all will be at a point disadvantage to the other PCs. Drawbacks and Edges need to be negotiated with the GM beforehand, so some back and forth will be needed to put together a viable character.
To get an idea of some of the things I have in mind, take a look at the sample characters. If you're worried that your character idea is insane, or too wacky, pitch it anyway - as long as it makes sense for the deep cover spy genre, I'll at least consider trying to make it work.
In addition to the mechanical aspects, I'll need a few background details on new characters. Follow the link for a full template character sheet.
