Verified answer
Does Control Resonant support Steam Family Sharing?
Quick answer
Yes. Steam lists Family Sharing for the base game, subject to Valve’s current account, region, and simultaneous-use rules.
What this means
Family Sharing is not a second permanent copy and does not guarantee that every Deluxe extra or future DLC transfers to another family member.
