Call of Duty: Siege

About

Call of Duty: Siege puts you in charge of the Retribution, a warship fighting to reclaim planets from factions that overthrew the United Nations Space Alliance. Build strike teams, manage resources, and balance attacks with defenses to hold ground. The game adds card collection to real-time strategy, letting you tweak units and abilities as you progress. A single-player campaign focuses on base-building and tactical positioning across space territories. Developed by Faceroll Games, the team behind Call of Duty: Heroes, Siege launched in 2016 for mobile. It mixes quick combat loops with longer-term planning, splitting time between battlefield action and strategic menus. Available on Android and iOS, it offers a portable take on the franchise’s military themes, blending base management with card-driven customization.
