[Update: Koei Tecmo has confirmed Warriors Orochi 4 Ultimate will arrive in the west in February 2020 on PS4, PC, Xbox One and Nintendo Switch. Ultimate will be available as a standalone release or a paid upgrade to the vanilla edition of the game.]
Following a leak from Amazon Japan yesterday, the new issue of Weekly Famitsu has officially revealed that Warriors Orochi 4 Ultimate is in development at Koei Tecmo, with a PS4 and Nintendo Switch release planned for Japan this December.
The expanded edition of this alt-universe battle sequel will include some 170 playable characters – including the all new Gaia – as well as returning heroes such as Warriors Orochi 3’s Joan of Arc/Jeanne d’Arc (sadly not played by Kate Wiedlin). New Sacred Treasures, side-quests, and crowd-clearing co-op moves will also be introduced, alongside a host of tweaks to Warriors Orochi 4’s control system, UI and HUD. Among the modes included are a survival-style Infinity Mode, as well as fresh maps for the original title’s Challenge Mode.
