I run primarily sci-fi campaigns, so I've been looking forward to the SWADE SFC for years (literally).
It will be roughly another year before we have the SFC companion mod in FGU.
If you're as excited about the SFC as I and my players are, you want to get to playtesting it now.
To that end, I created a temporary pre-release extension.

This is TEMPORARY, as in, when the official SFC module and extension are released, this one will be retired.
This extension DOES NOT and will not contain any information from the SFC. No edges, no star knight, no new powers, no vehicles.
Check the forum thread for updates and details.

What this extension adds:

• Strain limit and max derived stats on the player character sheet
• Enables bases and cyberware
• Clash token count, buttons for clash actions
  
• New fields on the vehicle sheet
• - title/class for heavy metal
• - energy
• - wounds max and current
• - shields max and current
• - current vehicle damage
  

This should give you a start on playtesting the SFC.
I'll add more features as the SFC matures and my group play tests the SFC and these features.
