DjMizuhara just got home from Tokyo but he nonetheless took the time to capture the first ten minutes of Ninja Gaiden Sigma 2. A second video will follow in a bit. Update: Third part is now up!

DjMizuhara obviously didn't miss the Japanese release of the demo of Ninja Gaiden Sigma 2 so here is the video he captured. More videos will follow so you can see the attract mode in action, as well as one of the exclusive lady characters missions.
Update 2: Ayane video added.

Tecmo has released the launch trailer of Ninja Gaiden Sigma 2 for Playstation 3. The game will be released on September 29 in North America and October 2 in Europe.

Tecmo has just released these images of Ninja Gaiden Sigma 2 showing the coop mode. The game will be released on Playstation 3 on September 29 in North America and a couple of days later in Europe.

Tecmo also released this video finally showing the coop mode of Ninja Gaiden Sigma 2 in motion, with Ryu and Momiji struggling against a quite vicious butterfly boss.
Update: Added a second coop gameplay video, with Ayane as the main character and Ryu as the helpful assistant.

Tecmo / Koei released these 6 new images of Ninja Gaiden Sigma 2 showing the coop mode in action. As usual these are obvious bullshots, but the game itself is still quite good looking.

The ink of the contract that now ties Tecmo to Koei isn't dry yet, but the japanese studio released a big bunch of screenshot of Ninja Gaiden Sigma 2 anyway. In these seventeen images, we (re)discover the main characters of the game in fierce situations. Above, Ryu Hayabuza about to perform a karate kick on a dragon.

Let's continue with DjMizuhara's videos and this time Ninja Gaiden Sigma 2, whose first level was playable.

Ninja Gaiden Sigma 2 had been a bit forgotten until now, but we finally managed to get the game's E3 trailer.

The official Ninja Gaiden Sigma 2 site had been updated with a HD trailer. The quality isn't great, but it's better than nothing.
