Here is the teaser!

Personally I like Team Ninja for this series and of course DOA & DOA Extreme Volleyball 2 ;]

This series is great! And well it is also hard. Possibly ninja gaiden is the series to come out with the most re-releases of one game. (AKA Ninja Gaiden, Ninja Gaiden Black Edition) I would look into these if you like running through a map and cutting down enemies for the greater good! ;]
