While Soul Sacrifice has an AI controlled partner in single player mode, creator and Comcept CEO Keiji Inafune designed it as a multiplayer game.

"I recommend the multiplayer mode where you can play with your friends or girlfriend. Because that’s when the emotions come out and everyone can feel the sacrifice," Inafune said during an interview with Siliconera.

The good news is you can sacrifice for your friends even if you’re a thousand miles away. Soul Sacrifice supports online multiplayer, Famitsu magazine reports.
