Infinity Kingdom casts players as a lord defending Norheim, a cartoon-styled fantasy realm threatened by invading players and a mechanical gnome army. Its premise ties recovery to resistance: the city has been ransacked, and rebuilding it helps restore a place of refuge while preparing its forces for the fight. That blend of settlement growth and external danger gives the strategy game a broader focus than battles alone.
Its army draws on more than 50 Immortals inspired by historical and legendary figures, including Cleopatra, Julius Caesar, Merlin and Robin Hood. Players summon these commanders and assemble troops, then weigh unit attributes and elemental advantages when forming a battle team. Dragons add another layer: players can hatch eggs, raise the creatures and pair a dragon with an Immortal of the same element to activate a battle buff. Ruins on the world map provide a different activity, with scouts collecting Stele Shards that reveal Norheim’s history through territory Monuments.
The listed formats include single-player, multiplayer, MMO and online PvP, alongside a PvE campaign mentioned in the game description. The central loop is therefore not simply assembling a force, but developing a city and a combination of commanders and dragons for several kinds of play.
