An announcement that should come as no surprise to anyone, Nioh will be getting a Complete Edition. The final slice of downloadable content for the samurai slasher was revealed recently, so it only makes sense for publisher Koei Tecmo to come out and tell us that it's stuffing the base game and all three of its expansions into one package later this year.
At the time of writing, the Complete Edition has only been confirmed for Japan, where it'll be available from the 7th December. We don't see why it wouldn't come West around the same time, however. Keep your eyes open for inevitable confirmation in the very near future.
