Yes, there are co-op elements in some Ninja Gaiden games. Specifically, "Ninja Gaiden Sigma 2" features a cooperative mode where players can team up in certain challenges. Additionally, "Ninja Gaiden: Master Collection" includes "Ninja Gaiden 3: Razor's Edge," which also offers a cooperative mode for specific missions. However, the mainline series primarily focuses on single-player gameplay.
At this point, Ninja Gaiden 2 has been released for only the Xbox 360. Because this game came out in 2008, it likely will never be released for any other video game system.
