Shadow Grenade is used as a diversion, engulfing a group of enemies into a puff of smoke, rendering them temporarily 'stunned.' Explosive Kunai throws an explosive shuriken, while Twin Shadow allows for the AI or online partner to perform a sneaky kill when initiated. However, there are three new abilities in addition to the already-existing Kage ability, which causes temporary invisibility.

Unfortunately, the story does suffer from an issue that plagues many prequel stories the end-point is known, making any sense of urgency in this story quite pointless. While playing as both delivers slightly different cut-scenes in some cases, it still tells the same story for the most part. Hyo and Shinobu, while providing new insights into assassins from the Nisshoku point-of-view, remain as different skins of the titular character. The prequel story is a bit light on delivering new information or context to the main game, and it rather seems to serve as a reason to jump right back into the gameplay and assassinate enemies, while keeping under cover of darkness.
