From the producers that brought you Caesary Online, Immortal King is a free to play browser mmo developed and published by Game321. The game takes a large-scale approach to the MMORTS genre, offering much larger fight scenes and a unique instance system, similar to the majority of dungeon-based MMORPG titles.

Although most RTS titles have a heavy focus on combat, Immortal King takes a more in-depth look at combat and combat mechanics allowing a players tactical decisions in combat to greatly influence the outcome of the fight. The game has 137 different types of Hero, which are the main units that command your army, and your army can consist of 72 different types of soldiers and units, all of which can be used differently depending on the combat formation you choose to put them in. This allows a skilled tactician to be able to defeat a far larger army with smart placement and intelligent tactics.

Most players will find themselves joining a League pretty quickly, a League is Immortal King's equivalent to a typical Guild type system, as a League member you're able to contribute to your Leagues level, technology rating and reputation, all by performing certain tasks. Although you can pay extra taxes, deposit special items or help research new technologies, the main purpose of the League system is League VS League combat. These large scale, up to 50vs50 fights, are mainly for bragging rights and resources, as 2 Leagues collide and battle, ownership of nearby Farms and resource fields will change hands depending on the victor.

The game is currently in an Open Beta stage after recently finishing its Closed Beta period and is available to play in all popular browsers free of charge. The game does feature an Item Mall system where you can purchase items to improve the power of your army, reduce building cool-downs or buy special equipment for your favorite Hero.
