Ninja Gaiden Black
Tecmo announced at E3 2005 that Team Ninja was working on Ninja Gaiden Black,[73] and later exhibited a working version of the game at the 2005 Tokyo Game Show.[74] Black is a reworked compilation of the original Ninja Gaiden and the two Hurricane Packs.[47] The game features new foes, such as exploding bats and doppelgänger fiends who can imitate Ryu.[75] It contains more costumes than the original, and swaps Ninja Gaiden's unlockable NES games for an arcade version.[76]
One key feature of the remake is its two new difficulty settings—the easy 'Ninja Dog', and the very hard 'Master Ninja'.[citation needed] Itagaki added Ninja Dog after receiving complaints of Ninja Gaiden being too hard in its default incarnation,[77] although he believed that, with persistence, any player was capable of completing the game.[78] Hence he ensured that those players selecting Ninja Dog would be subjected to gentle mockery by the game—players on this difficulty setting receive pink ribbons as accessories, and Ayane treats Ryu as an inferior. In compensation, Itagaki made the other difficulty settings harder than in Ninja Gaiden. Ryu's adversaries were strengthened and made more aggressive, and some of his offensive moves, such as the Flying Swallow, were toned down.[citation needed]
Another feature of Black is its Mission Mode, which comprises 50 combat missions, one of which is adapted from the custom game designed for the Ninja Gaiden Master Tournament World Championship final. The last five missions are based on those in Hurricane Pack 2, but with the Black game engine, and form a linked series known as "Eternal Legend".[76]
[edit] Ninja Gaiden Sigma
In 2006, Tecmo and Sony announced the development of Ninja Gaiden Sigma for the PS3.[79][80] Eidos obtained the European publishing rights for this game.[81] Itagaki had no direct role in Sigma, and judged it a flawed game,[82] although he acknowledged that Sigma gave PlayStation owners a taste of Ninja Gaiden.[83]
The Cell processor of the PS3 gave Team Ninja the opportunity to overhaul the game graphics to use larger and more detailed textures.[4] Changes were made to the game world, with a few new areas and several additional save points and shops,[84] and alterations to the game engine let players shoot arrows in mid-air, fight on water surfaces, and play as Rachel in some chapters and missions.[4][85] Team Ninja added more enemies such as bikers, fish-men, and a new boss, Gamov, and Ryu's weapon choices are extended with a pair of katanas called the Dragon's Claw and Tiger's Fang.[4][84] By shaking the Sixaxis controller, players are able to increase the power of their ninpos.[86]
Although marketed as the "more complete" version of Ninja Gaiden by many gaming sites,[87][88][89] Sigma omits a few features found in the Xbox games.[Neutrality disputed — See talk page] It does not have the opening movie or any of the unlockable classic games (the initial Xbox release of Ninja Gaiden contained the SNES versions of Ninja Gaiden 1, 2 & 3, while Ninja Gaiden Black had the arcade version of Ninja Gaiden) and is missing one costume from the original, while missing two costumes that were available in Ninja Gaiden Black.[4][85][90] In Japan, Tecmo engaged a local-based singer, Leah Dizon, to promote Sigma. She appeared in a commercial and sang its theme,[91] and signed posters that Tecmo gave away at the game's launch.[92] In North America, GameStop sold special editions of Sigma in their stores.[93][94][95] These editions have an exclusive "behind-the-scenes" DVD, and contain a code that unlocks extra missions. However, the code proved to be usable on normal copies of the game also.[95][96]
In 2007, Tecmo released a demo and a new game mode, Survival Mode, for Sigma over the PlayStation Network.[97] The demo limits players to the first chapter of the game, but lets them play as Rachel in a separate mission.[98] Survival Mode comprises missions in which players keep fighting until they have either killed all their opponents, or their character has been defeated.[99]
