There's several routes - and as such several ways to play - in Adventure High.
Heroic Path
The Protagonist uses his/her power for good and refuses to enslave anyone. Instead, the Protagonist will focus on stopping Drape from taking over school.
At the moment, there's two Mind Dungeons on this route: Val's Mind and Sarah's Mind.
Tempted Hero
During Tempted Hero, the Protagonist has enslaved at least one other character.
Faculty Control
This route focuses on enslaving the teachers. At the moment, Ms. Rack, Dr. Tiff and Jane (though through alternate means compared to the first two) are possible to enslave.
Student Control
This route focuses on enslaving all students in the school. At present time, Val, Sarah, Julia, Cassandra, Ashley and Molly are possible to enslave.
Redemption
During the Faculty Control path, enslave Ms. Rack. Once done, meet Val in the street and she'll explain that Dr. Tiff broke her free from your mind control. Talk to Dr. Tiff and turn in the rest of your slaves to revert them back to normal. There's currently nothing on this route.
Submissive Slave
If you lose the battle against Cassandra, she'll refer to herself as the Protagonist's Mistress. You can also enslave Sarah to become Cassandra's slave during this route.
Curing Ashley
Julia's lost big sister... Are you capable of helping her regain her senses? Or will she always be a mindless fighter, doing nothing but lusting after the next fight? Find out in this plotline.
