Battle of the Kings is best described as a blend of role-playing game, real-time strategy game, and management simulation. The mod features two factions: a Red and a Blue faction. At the start of the game, players can choose their preferred faction, guild, difficulty level, and map. Soldiers from both factions automatically attack the enemy faction at regular intervals after the game begins. The primary objective of both factions is to defeat the enemy king with their own soldiers. Players can upgrade their soldiers, crafting better weapons and armor, or recruit mages to support their troops and increase their gold income. Players do not actively participate in combat. They can move their character around the world as a passive observer, unable to deal damage or be attacked. Although the mod is relatively simple, it offers numerous ways to win or lose. The game is completely flexible and entertaining for casual players, number crunchers, and professional gamers alike. The modification also includes new music and plenty of introductory tutorials, which is why this graphically understated modification has become quite large. Battle of the Kings 3 includes the second part and expands it with several new features: In addition to a changed difficulty level and another faction (the Undead), there is another map that features a new skeleton cave. Both players can send soldiers into the skeleton cave, and the soldiers controlling it are supported by additional skeletons. Another significant new feature is the implementation of a hero: Using an "Elite," you can now hire a hero who will automatically enter battle and level up for each enemy defeated, thus becoming more powerful. Furthermore, you can upgrade the hero's armor, melee weapon, and crossbow - making the hero an effective weapon against the enemy. Furthermore, at the beginning of the game, the player can activate some special options (such as eliminating mercenaries or spawning more soldiers) with the game administrator, and important events are now communicated to the player by an announcer.
