HARP SF and HARP SF Xtreme now in print!

[NicholasHMCaldwell]

so can I play harp sf with just the extreme book or do I need both to play?
is harpsf extreme just an add on supplement?

The SF flavour of HARP comes in two parts , HARP SF and HARP SF Xtreme. You can play with just HARP SF but if you want vehicles,  vehicle combat,  cyberware, and robots, you need Xtreme. So a bit more important than an ordinary supplement.

Best wishes,

Just to be clear - HARP SF Xtreme cannot be used alone. It requires HARP SF
