Those still curious over the multiplayer elements of Catherine should turn their eyes to Famitsu, which has explained it in more detail.
As reported before, the multiplayer can be accessed through the modes Babel and Colosseum. In Babel, which is playable in both solo and multiplayer, there are four stages which can be unlocked as achievements when playing the game’s story mode – but only on Normal or Hard, not Easy. Babel has online rankings, as well, which was already detailed as well.
Colosseum mode is two player only, and like Babel, you unlock it once you have completed the story mode; however, instead of controlling Vincent, you are in control of sheep men.
The newest details on the Colosseum and Babel modes have been translated by Andriasang, so if you can’t read Japanese, that’s the place to go.
A demo for Catherine was released on PSN and XBL in Japan earlier this week.
