It’s the Koei Tecmo way
Koei Tecmo might be bad at doing quality PC ports, but it has a good grasp on console development, and generally does a great job of supporting its games over time. That’s also the case for Attack on Titan, which is getting a massive four player co-op multiplayer update on March 24.
Other paid add-ons are also going to be released over the next few months, as well as a number of enhancements, like costumes weapons, and more episodes. You can probably expect most of this to also see a release in the western version, which is due sometime this year.
