Set in 2155, Global Agenda casts players as special operatives resisting the Commonwealth, an oppressive government that emerged after the Third Great War. Its science-fiction conflict centers on competing factions, advanced warfare, and a race for technology. Players create and develop multiple agents, pairing first-person-shooter skills with RPG-style progression and a broad arsenal of futuristic weapons and devices.
The game moves between cooperative missions and competitive battles. In online co-op, teams of four infiltrate facilities, defeat end bosses, and earn technology upgrades. PvP offers objective-based team matches, including 10-versus-10 Mercenary combat and 4-versus-4 Arena fights; a separate Double Agent mode is also listed. Beyond individual matches, agencies compete for territory and limited land resources, giving the game a persistent factional contest alongside its mission-based play.
Its documented modes range from co-op groups to larger team battles, while agent progression and specialized equipment frame the action.
