Thanks from the entire team!
Foci upgrade rules were already in previous versions, but we tweaked them a bit.
We heard from many, many, many GMs and players concerning cyberware upgrades, so we came up with something we hope will help.
We are discussing cyberdecks and RCCs and how we want to do it. We know our deckers and riggers have a difficult (if not impossible) time upgrading. Keep your eye out for the next version...we should have it addressed by then.
