You Get One Free Edge
While Weird War Two has some additional steps and options for character creation, it builds upon the Savage Worlds core rules. Which means it follows those core rules.
In the Savage Worlds core rules (original, Revised, Explorer, Deluxe, or Adventure editions), Edges are provided by a source. That source may be Race, a setting rule, or by spending points from Hindrances.
To quote Savage Worlds Deluxe pages 16 & 17:
Humans are the standard race in Savage Worlds, and start play with one free Edge (see Step 3).
Characters can take Edges by balancing them out with Hindrances. You’ll find a complete list of Edges and Hindrances later in this chapter. Look for more in our Savage Settings.
You can take one Major Hindrance and two Minor Hindrances. A Major Hindrance is worth 2 points, and a Minor Hindrance is worth 1 point.
For 2 points you can:
• Choose an Edge
WW2 doesn't change that. Characters are human, and gain one free Edge because of the human racial ability. There is no Setting Rule that provides additional Edges. And the rules for Hindrance points remain the same.
For informational purposes: PEG Inc. (the publishers of Savage Worlds and Weird War Two) have a forum with a section for asking for official answers to rules questions about their settings.
