You go into Mind Control Training when you get Mind Control.
This is how you complete the training:
- Use MC on the Meat Puppet next to you, and make him unlock the door.
- MC one of the Meat Puppets next to you. Have him shoot the barrel next to the other.
- While hiding, MC one Meat Puppet, and have him kill the other two.
- Have the meat puppet you are kill himself with an explosive barrel.
- Go into the next room, and kill five Meat Puppets with MC.
