Post the Ninja Gaiden 4 announcement, Xbox's chief shares the company's enduring push for a new sequel in the long-running action series.

Ninja Gaiden 4, a surprise announcement last week, is already 70-80% complete. In fact, the game is currently being polished ahead of its launch on the PS5 later this year.

Today, during the Xbox Developer Direct, Koei Tecmo announced Ninja Gaiden 4, a new 3D action game that continues the story of Ryu Hayabusa. The game will be made in collaboration between Koei Tecmo's internal Team Ninja team and Platinum Games.
