Tower of Fantasy

Tower of Fantasy is a free-to-play open-world action MMORPG developed by Hotta Studio and published by Level Infinite (a Tencent brand). Set in a post-apocalyptic sci-fi world on the planet Aida, players explore large shared environments, collect Simulacra (character weapons with distinct skills), and progress through a gacha-based gear system. The game features real-time combat with a focus on weapon-switching combos and elemental reactions, open-world exploration with climbing and gliding, and a variety of instanced and open-world co-op content including raids, world bosses, and competitive modes. The global PC version launched on Steam in August 2022, built on Unreal Engine 4 with full cross-play between PC and mobile.

Tower of Fantasy uses regional dedicated servers split across multiple zones — North America, Europe, South America, Southeast Asia, and Japan/Asia-Pacific. Players choose a server at character creation and are bound to it, though cross-region matchmaking for instanced content exists. The game has been a prominent entry in the competitive gacha MMO market alongside Genshin Impact, with consistent updates, new limited characters (Simulacra), and seasonal content. Player activity on PC (Steam) has declined significantly from its 2022 launch peak, but the mobile playerbase remains substantially larger, with the combined population estimated in the hundreds of thousands monthly as of early 2026.
