Ovewr the years, Sega has released a variety of series that span far throughout its history of consoles. One series of games that has been dormant for a long time is the Shinobi series. Originally started as an arcade game in 1987, Shinobi underwent many changes over the decades, starting as a 2D action-platformer and eventually becoming a 3D action game on the PlayStation 2. The series eventually made a return to its 2D roots on the Nintendo 3DS in 2011, before taking a long hiatus for the next decade. Fans were wondering if Sega would ever revisit the series in a big way after pledging to revitalize many of their classic franchises for modern consoles.
