Being a remake of The Caligula Effect published in 2016 on PlayStation Vita, The Caligula Effect: Overdose is a jRPG. The original game was developed by the creators of Sword Art Online: Hollow Realization, whereas the refreshed version is created by Historia.


The action takes place in Moebius. What on the surface looks like contemporary Japan, really serves as a virtual prison for people tired of real life. They seek shelter and try to forget their earlier lives by repeating an endless cycle of attending high school. Controlled by the player, the heroes learn the truth about this place and decide to escape. Importantly, the plot is constructed by Tadashi Satomi, the person responsible for the story, world, and characters from Shin Megami Tensei: Persona, Shin Megami Tensei: Persona 2: Innocent Sin, Shin Megami Tensei: Persona 2: Eternal Punishment, and Shin Megami Tensei: Digital Devil Saga 2.


Mechanically, The Caligula Effect: Overdose is a classic jRPG. The player spends most of the time exploring, chatting, developing the character, and fighting turn-based battles.

The party is composed of up to four characters from a wide range of heroes we meet during gameplay. Establishing relationships with over 500 characters plays the key role in the game. These relations bring a few additional development options and access to special items.

In comparison to the original game from 2016, The Caligula Effect: Overdose is much larger. There are new scenarios, alternative endings, and loads of new characters. All in all, the game is twice as big, as there are fresh, alternative plot branches. Now we can become a double agent and infiltrate a faction that served as the main enemy in the original game.

Technical aspects

The title utilises the power of Unreal Engine 4, so all visuals are significantly improved.
