On this page of Psychonauts 2 guide you will find information about the health of the hero. You'll find out where to find it and how to heal.
Health points - Mental Energy
Health points will appear on the first level, when fighting the first enemy. They are presented in the form of brains, which are shown in the upper left corner of the screen.
The basic amount of mental energy is 3 brains, each of which is divided into 4 parts. They are damaged depending on the strength of the enemy.
The amount of mental energy can be increased during the game.
After losing all mental energy points, the game will move you to the last save point, for example, to the moment of changing locations.
Healing in Psychonauts 2 is represented by green pluses. You will find them in different parts of the map, most often in water distributors. They glow green so they're easy to spot.
