Wild Hearts is now available on EA and Omega Force for download today, March 27, 2023. The intention of the patch is to address some previously unknown issues as well as to improve the CPU performance for the PC version of the game.
Official updates of the update, which you may find at this address, are currently only in English, but without adding further information.
Changes have also been made to the weapon upgrade system, including the addition of new connection nodes between various types of weapons. There are also opportunities for various modifications, such as the possibility that the first attack of "Unbound: Iai Sunder Slash" of the karakuri katana would not be successful on PC if the framerate had been limited to 30 frames per second in the graphics options.
The bigger update on March 23 included Wild Hearts, a new Grimstalker kemono, three new high-difficulty quests, weapons, and the Fulgent armor set.
