Healing items were increased and are the only thing one can buy. Projectile spam was greatly reduced from NGII. Thus, the two weapons bulk up Ryu's appearance even though they do not appear in cutscenes. The player cannot unequip the bow or cannon. This allowed both the Bow/Cannon to be equipped at the same time as the shuriken. Other ranged weapons were separated to the R2 button. In the gameplay control system, the action button changed from RB/R1 to circle, circle is now also the shuriken button. Tests of Valor were also removed, scattering the rewards across Ryu's chapters. In Story mode, Karma Scoring is removed and now only done in Chapter Challenge. With Team Mission mode, where two players can play at once in cooperative gameplay, the second character will be CPU-controller partner if there is no human partner or the player is offline. While Sigma 2 has additional content not in the original Ninja Gaiden II, a large amount of content was also removed from the game, or altered, such as a drastically reduced enemy count within gameplay. Unlike the first game, the Sixaxis motion sensing of the PlayStation 3 controller was not used for 'charging' the Ninpo magic, but instead utilized as a secret way to jiggle the breasts of female characters. In comparison to the original version of Ninja Gaiden II, the game features new large-scale bosses, an online co-operative gameplay mode with three new playable characters ( Ayane, Momiji, Rachel) and the PlayStation Network Trophy support.
