If there’s one thing Activision is known for its milking franchises and the Call of Duty: Modern Warfare is their biggest cash cow. Freshly filed trademarks suggest spinoffs are in the cards.

The mega publisher just registered trademarks for Call of Duty Space Warfare, Call of Duty Secret Warfare, Call of Duty Future Warfare, and Call of Duty Advanced Warfare. In addition to those, Activision also filed paperwork for Secret Warfare, Space Warfare, and Future Warfare individually.

Prepare yourself for Call of Duty space marines, people.
