Kings of Chaos (KoC) is a free, browser-based, text-based MMORPG that started as a high school project in 2002 and grew to have hundreds of thousands of players. Players build armies, attack other players, and manage resources in a turn-based strategy game that involves choosing a race, training soldiers, and upgrading stats like attack, spy rating, and defense. The game is structured in "ages," with a focus on player-versus-player combat, resource management, and strategic upgrades, and it has evolved over time with community involvement.
