Today, during a live stream for Nioh, Koei Tecmo revealed details about the upcoming post-launch support that Nioh fans should expect.
As translated from Gematsu:
To begin, expect free content to arrive in late March, this will include high-difficulty missions that will include boss rushes, there will be 10 missions in total.
In April, we should see PvP implemented into the game, a feature sorely missed when Nioh launched earlier this month.
The first DLC will be called Dragon of Tohoku and will feature new weapons types, new scenarios, new characters, new guardian spirits, new yokai, and new stages.
This will be followed up with another piece of DLC called Japan’s Best Warrior and Peaceful and Tranquil.
