If you are getting started with Scrappers, or you just need a tool to help design your Crew here you can find a file that a friend of mine has done on excel .
It is a pretty cool tool with a builder tab where you create your guys and then a couple of summary tabs that collect all the data for your crew, even a tab where this data gets incorporated into the Roster.
You still need to read the design rules in detail, the validation is not strong enough to enforce all the creation rules, it is only there to easy the process of selecting traits and equipment. It does have a couple of checks to avoid silly mistakes.
I'll post this link to where the file resides since we will keep updating it over time.
