The more we learn about Tokyo Ghoul: re Call to Exist, the less I feel I know about the game. But I will say this, the game looks fantastic from what was shown to us.
According to Bandai Namco Asia, translated by Gematsu:
Bandai Namco Entertainment, along with [One Piece: Romance Dawn and Assassination Classroom 3DS developer] Three Rings, has announced Tokyo Ghoul: re Call to Exist, the first video game based off the popular dark fantasy manga series to come to the west. Tokyo Ghoul: re Call to Exist will feature fast-paced multi online co-op play in which the goal is to survive. Fans can enter the war against Ghouls and Investigators on either side when Tokyo Ghoul: re Call to Exist comes to … PlayStation 4 computer entertainment system and PCs via Steam.
Tokyo Ghoul: re Call to Exist will unite characters from across the franchise, including Tokyo Ghoul, Toyko Ghoul √A, and Tokyo Ghoul: re in the fight for survival as either a Ghoul or investigator. Ghouls and Investigator character types each possess their own unique abilities and weapons to master, including Kagune or Quinque type items. Players can pick their sides and challenge friends to see who will reign supreme in gruesome battles to the death.
From the brief gameplay that we saw from the trailer, it seems there’s a mix of heavy combat and shooting involved. The shooting looks similar to what I’ve seen in Black Clover Quartet Knights while the combat looks vicious as hell. The multiplayer aspect still remains a mystery but if the action from the trailer is anything to go by, the I’m sure the Multiplayer will be some heat.
