Ninja Gaiden Sigma is the second remake of Ninja Gaiden, and incorporates several features found in Black. Although marketed as the "more complete" version of Ninja Gaiden, Sigma left out most of the bonus features in the previous two versions. It has fewer unlockable costumes, and has eliminated the old SNES and arcade unlockable games. It also cut out the introductory movie concerning the legend of the Dark Dragon Blade and the Dragon Sword, and the option to play CG cut scenes outside of Story Mode.
Hayashi's team used the Cell processor in PS3 to overhaul the graphics of the game engine to high definition standards. They changed the design of a few levels, added several save points and shops, and inserted Rachel's three chapters within Ryu's Story Mode. Sigma tweaked several enemy settings and introduced new foes, such as biker MVAPs, fish-men girtablilu, and wisp-like phantoms; and two new bosses, Gamov and Alterator. The player can fight these foes with the new weapon, a pair of katana named the Dragon's Claw and Tiger's Fang.
Sigma allows the character Ryu to fight on water, and shoot arrows in mid-air. Ryu can now do a backflip without walls by pressing the Left Thumbstick. Prominent changes include letting the player use restoration items without going through menus, and shake the Sixaxis controller to increase the power of ninpos. The game also rewards players bonus yellow essence for their first game based on their time spent playing the demo. Sigma offers three separate packages which can be downloaded from PlayStation Network for a small fee. These packages themed Weapon Master, Speed Master, and Rachel Master make up Survival Mode; and feature missions in which players keep fighting until they kill all enemies or their character dies. A separate online ranking system for Survival Mode ranks players by their number of kills.
- Strangely, although Team Ninja removed the Dark Dragon Blade/Dragon Sword Intro, the narrator is still listed in the credits.
