Tecmo Koei will push out free content updates for Ninja Gaiden III fans.
Andriasang reports the DLC was briefly mentioned in this week's Famitsu.
Although details are slim, it seems the packs will mostly focus on new weapons for Ryu Hayabusa's arsenal. A claw and a scythe were mentioned.
The packs have not been confirmed for western release but the publisher is usually quite thorough in bringing extra content over. No word on further updates or paid packs, but as Ninja Gaiden III sports a multiplayer mode it seems quite probable.
The tough-as-nails Ninja Gaiden 3 releases on PlayStation 3 and Xbox 360 on march 20 in the US and March 23 in Europe. A Wii U version is to follow.
