A much better question, which may have been asked before and I can't find the answer:
Is it possible for a Technomancer to develop Noise Reduction and/or Sharing for drone control? If so, how?
Not in the core rule book, but this functionality might be in future source books.
So, if someone were to take an arrowhead and the shaft of the arrow, have them in to different pieces, and then use them as lynchpins to create two different preparations, would they still be considered as two different preparations when reassembled into an arrow? If so, what happens if the preparation on the arrowhead is Contact activated?
I think that strictly by the book, they'd remain two separate preparations. I think the errata will show that destroying or defacing a lynchpin destroys the preparation, but whether attaching an arrowhead to an arrow shaft defaces a preparation is a GM call (which might involve and Armorer Test). If the arrowhead has a contact trigger, the arrow would have to be handled and shot without touching it, and it would have to penetrate (cause Physical and not Stun damage) its target for the contact trigger to ... well, trigger.
What I'm looking for here is dev response so I can get a closer sense of what RAI here is.
Please keep in mind I'm keeping my answers based on the book and any errata I know has a good chance of making it through the approval process, labeling my own opinions as such. In theory, the Real Answers are in the book, albeit possibly buried somewhere in its nearly five hundred pages. Beware of using my opinion in your rules debates, partly because appealing to authority isn't a valid argument, but mostly because nothing's official unless it's in publication by Catalyst.
Also, a lot of these questions are becoming more and more centered on minutia and weird edge cases, and so they don't really fall under the "F" in "FAQ." That said, I like answering questions so I don't mind answering them (although the
really specific ones probably won't make it into the official FAQ when that becomes a thing.
Q: Adrenaline Boost is a Free Action and makes you eat drain the next turn. No limit in use is mentioned. Can you use it in multiple Action Phases in the same Combat Turn? If so, does the drain stack up in one massive drain check, or will it be several independent drain checks?
Barring errata, you can use it every Initiative Pass. You'd take the Drain from each use separately.
How does evading explosives work? If the defender wins a test against a motion triggered grenade (same with vehicle vs missile), will he take no damage at all? Will he jump like 10+ meters away in spaces without obstacles/cover? If he doesn't, he should have to soak part of the blast (but how much?).
If you're in the blast zone when the explosive goes off, it's too late for you to evade it. Motion triggered grenades go off when they hit you; if they miss they scatter (p. 182) and so might take reduced damage.
Q: Scatter mentions (#d6 - Hits) meters in Scatter. Motion sensors mentions scatter the grenade "scatters the full amount". Does that mean that, unlike with an unopposed test where scoring 1~2 hits will reduce the scatter, you do not apply any hits from the opposed test on reducing the scatter? Or will the net hits of the defender actually count against you, increasing the scatter?
In the case of a missed motion triggered projectile, roll for scatter but do not reduce the scatter by the attacker's hits.
