Spec Ops is an ongoing military video game franchise, created by Zombie Studios executives. The games have primarily been launched on the PC, PlayStation and Dreamcast systems. The first few titles in the series were developed by Zombie Studios, and later titles by Runecraft Ltd. The same goes for publishers: initially the games were published by Ripcord Games, and later by Take-Two Interactive. Other developers and publishers have since been brought in for spin-off titles and ports.
The Spec Ops franchise was intended to be a realistic first/third person shooter experience and immerse the player in the world of international terrorists and the like with the player trying to stop them in a two man team, originally developed by Zombie Studios and published by Ripcord Games for the PC. The first two games were well received; and the PlayStation and Dreamcast sequels (developed by Runecraft) were more of a budget priced shooter experience, giving them lower review scores.
