That’s my understanding of the remote rules on pp354-5 of the corebook.
When operating something as a remote, you (or your Geist) make skill checks using your skills, with the remote providing an Assist action using the remote’s inherent abilities - and a +2 complication range (or +1 if using VR mode because you don’t care what happens to your meat body).
When “jumped in”, I believe it’s the same, but without the increased complication range. Although it’s not clear whether you still get the Assist from the remote’s own LAI/expert programs.
It does specifically state on p355, that …
Physical attributes (Agility, Brawn, and Coordination) are still capped by the remote’s limitations
… which I would take to indicate that the controlling sheut/Geist’s abilities would be used for skill checks.
I’m trying to recall whether there are any expanded remote rules in any of the other books.
Which is a hideously long and wordy way of saying “Yes, I think so.” Sorry!
@Modiphius-Nathan, have I got that right? And do you still get the remote’s Assist when jumped in? Cheers!
