Considering this is still a Warriors game, its place in the franchise is explained on Steam with:
To get a sense of the massive content offered in the Warriors Orochi 3 Ultimate Definitive Edition, there are 145 characters as well as Dynasty Warriors and Samurai Warriors characters. Not only those, but characters from other Koei Tecmo published games such as Dead or Alive 5 and the Atelier series make an appearance.
Warriors Orochi 3 Ultimate Definitive Edition is available right now on Steam for $39.99. If this game suits your fancy, Warriors Orochi 4 Ultimate is also available on Steam.
