Koei Tecmo is developing one hundred of new musous right now, but there is room in the company workflow to develop games from different genres. Apparently, the company is working on a new hunting game ala Monster Hunter, if the info is accurate, the title will be published by EA in the first months of 2023.
Jeff Grubb states that the game is going to be unveiled today (or soon).
What to expect about Wild Hearts? Koei Tecmo had some experience in the hunting game genre with Toukiden. Therefore, they could be developing something in that vein or with mechanics with resemblances to that franchise.
Thanks, Resetera.
