Worth ten points.

Summary
This is a little obscure to get as well. First, at the very start of the game, choose the Robot Companion beginning. Go through the game as normal, but make sure your Empathy stays rather low. Some people say don't go above 15...I was able to get around with 11 to 12. It is possible that it could be even lower.

The key moment then comes at the end of Ch. 5. You will experience the dream again, but your Robot companion will crumble away saying you didn't have the Empathy to build robot companions. However, an alternative will be presented, one which scoops out part of your brain to put into a robot. This will get you the Achievement.
