Naruto Shippuden: Gekitou Ninja Taisen Special – Save Games

Unlike modern fighting games that allow microtransactions to skip progression, Gekitou Ninja Taisen Special operates on an old-school grindy system. Upon starting the game, you have roughly 10 characters: Naruto, Sakura, Kakashi, and a handful of others.

A hidden feature in the Gekitou Ninja Taisen series (often found in previous titles and reportedly present here) allows you to unlock all characters simply by having a cumulative across all modes. If you're stuck on a specific Gekken Road mission, sometimes simply leaving the game running in a menu can eventually grant you the full roster.

Fun fact: The Japanese “Special” version actually released only in North America and Europe under the Revolution 3 name. There is no true Japanese retail version.

Many players find the unlocking process "tedious" and turn to external save files to skip the grind.
