Tecmo has announced the release of Ninja Gaiden Sigma 2 and Undead Knights for PS3 and PSP respectively. Ninja Gaiden Sigma 2 features characters from the previous installments that have defined the franchise, as well as both melee and long-range battles against enemies. Ayane from the Dead or Alive series and Momiji from Ninja Gaiden Dragon Sword appear as sexy new playable characters. Undead Knights atypically allows you to be the 'evil' main character who serves as an anti-hero figure. You have to defeat as many enemies as you can to transform them into zombies that become part of your clan. You can control your zombies by giving them direct commands such as 'throw', 'charge', and a special action.
