You can automate cybernetics by just toggling them on in your medical screen, they'll show up next to your normal fleshy limbs if available. Characters are a single entity whose turns are the use of one skill and item at a time, but cybernetics that extend themselves, like tentacle arms or floating robots, are controlled as individuals with their own AI and turns, effectively making them like companions attached to you. Each of these entities get their own tile that can take damage (fortunately sometimes in place of you). You'll be able to direct some commands to them from the companion dock.

During development we split the design of cybernetics and items, so things like harpoons and 1-time use objects are now just going to be items you carry, and things that operate on their own are cybernetics. We found the previous system limiting, as their isn't action points to distribute we can go off the rails and just have lots of things taking turns at once. You can toggle enhanced armor, vision, reflexes, laser arms or more powerful melee attacks, but you'll be equipping items for your own ticks.

To run cybernetic hardware you’ll need to have battery packets in your inventory. These take up some room and are heavy, so if you’re doing a cybernetic-centric build your inventory will resemble a power station and you'll need the Vigor to carry it all.​
