Uprising: Join or Die, also known as simply Uprising, is an action real-time strategy video game by American developer Cyclone Studios, released in North America on October 14, 1997 and in Japan on July 24, 1998 for Windows. The player controls a powerful combat vehicle known as the Wraith that transports rebel units onto the battlefield, fighting against the military. For the first few months of its development, it had no script written for it and as the release date neared, gameplay videos were created to demonstrate its support for the 3dfx graphics card. It received a port to the PlayStation as Uprising X, which was released in December 1998; and before that, a sequel, Uprising 2: Lead and Destroy, was released for the PC on December 9, 1998.
