I'm looking through my new (to me) Genesys book, and I don't see any mention of harpoints on weapons, armor, or vehicles, nor do I see any mention of attahcments. Am I missing it or am I going to have to port it over from the Star Wars system (not that it would be that hard)?

Hard points are equal to half the encumbrance of the gear.

Starts on page 206.

Nice to know, I was missing this also. It's half the encumbrance rounded up.
