Honor of Kings is a multiplayer online battle arena game developed by TiMi Studio Group and published by Tencent Games for iOS and Android mobile platforms.

First released in Mainland China on November 26, 2015, the game has become one of the most relevant MOBA games in the country. An international adaptation entitled Arena of Valor, was released on October 12, 2016 in Taiwan; it used the same game engine but the user interface and hero design were heavily changed to accommodate the Western market.

In June 2022, Level Infinite, publisher of Arena of Valor, announced that Honor of Kings would be released globally in late 2022.[2] In May 2024, a worldwide launch was announced on June 20, 2024, following pre-release in Brazil and Turkey as well as countries in the Middle East, North Africa, and the Commonwealth of Independent States (former Soviet Union countries).
