About Ambrus Studio
Ambrus Studio is a game development company founded in December 2021 by Johnson Yeh, the former CEO of Riot Games Asia-Pacific, who is widely regarded as the 'Godfather of Esports in China'. Yeh, who holds a Ph.D. in strategic management, left his role at Riot Games to establish a company that aligns with his passions, aiming to leverage blockchain technology to solve issues within the gaming industry rather than focusing on a pure play-to-earn model. The studio's team includes veterans from prominent game companies like Tencent and miHoYo.
The company's core mission is to create high-quality, free-to-play games that bridge the gap between traditional Web2 players and the Web3 ecosystem. Ambrus Studio operates with a vision of “Good Games for Good Cause,” intending to raise awareness about climate change through its game narratives. The studio’s flagship project is the E4C (Earth 4° Celsius) ecosystem, which includes several games. Their first major title is 'E4C: Final Salvation,' a mobile-native MOBA (Multiplayer Online Battle Arena) eSports game. Other games in development or released include the Telegram-based mini-game 'E4C: Demon Hunter' and a PC game, 'E4C: Fallen Arena'.
Ambrus Studio's business model focuses on making free-to-play games profitable, particularly in emerging markets like South Asia, the Middle East, and Africa. Monetization is driven by leveraging Web3 technologies, such as dynamic NFTs on the Sui blockchain, to create infinitely personalizable and tradeable in-game items like skins. This model aims to create new revenue opportunities for creators and influencers who can co-create and sell their own branded skins. The company has secured significant funding, including a multi-million dollar Series A round led by The Spartan Group and a $15 million investment from Bolts Capital to enhance AI-driven game development.
