For example, if you had 2 cerebral boosters would the 2nd one even do anything?
Not that I am aware of. Does the game even give you the option to install a second one?
They don’t stack. The code basically checks if you have one or not.
You can’t get two of anything but power storage cbms through normal game play.
That is what I thought.
They do stack with stat effecting mutations and I believe there are two strength cbms an active one and a passive one which stack.
Good point about mutations and CBMs stacking.
And good point as well about Muscle Augmentation and Hydraulic Muscles.
