One of the new features in The Caligula Effect: Overdose is the option to betray the Go-Home Club and side with the Ostinato Musicians to preserve the false utopia of Mobius.
In the meantime, you can watch the Caligula anime on Crunchyroll.
Decide where your loyalty lies when the enhanced version of the RPG hits PS4, Switch, and PC on March 12, and see what the Ostinato Musicians are all about in the new English trailer below.
