Infinity Kingdom elevates mobile strategy by introducing a unique immortal summoning system allowing players to recruit legendary historical and mythological figures as powerful commanders. The game’s world is besieged by gnome armies, and players must form alliances drawing on heroes from different civilizations and time periods fighting side by side. The four elemental attributes create a matching system generating powerful synergy bonuses between immortals. The alliance system requires sophisticated internal organization and external diplomatic management for success. Dragon training provides an additional power dimension with players nurturing dragons serving as battle companions. The research tree offers hundreds of technology upgrades across military, development, and magical specializations. Infinity Kingdom differentiates itself through its mythological character integration system creating a compelling historical fantasy mashup.
