Kadinche Corporation, in collaboration with Sony Group Corporation, developed the basic technology for the VR event “Sword Art Online – Ex Chronicles – Online Edition” which was held from November 20, 2021.

The event was held as a VR event where visitors could enjoy heated battles with bosses appearing in the work and a wide variety of gimmicks and content unique to VR.

Kadinche Corporation developed an MMO front-end system using the Unity game engine and a back-end system capable of withstanding high loads using Microsoft Azure. These systems made it possible for multiple people to enter the VR space at the same time and enjoy contents and communication such as voice chat in real time.
