TFT shifts to Unreal Engine with Set 18, aiming for a future-proof upgrade
Teamfight Tactics is migrating from the Hextech engine to Unreal with Set 18 (not a sequel), signaling long-term innovation; a dedicated TFT client will arrive four patches after launch (around Oct 9), while the PC client stays on Hextech until then. Logging in remains via Riot accounts, and a four-week PBE starts July 14 to test Unreal. Settings will reset during the transition; the initial Unreal patch will be larger before patch sizes normalize. Cosmetics will port to the new Loadout and RP/currencies carry over. Existing Little Legends can be used as ARAM companions before the switch, but ongoing support for ARAM companions for new Little Legends will end long-term. Minimum specs remain similar for mobile with Android/iOS thresholds and PC requirements of Windows 10, DirectX 11, Shader Model 5.
