Teamfight Tactics is about to go through one of the biggest technical changes in its history, but Riot Games wants players to know one thing clearly. This is not TFT 2, and the game should not suddenly feel unfamiliar when Set 18 arrives.
Starting August 12 with the release of Set 18, TFT will move from Hextech, the shared engine it currently uses with League of Legends, to Unreal Engine. On paper, that sounds like a massive shift. In practice, Riot says the first Unreal-powered set should still feel very close to what the TFT players already know.
The bigger changes are happening behind the scenes. Riot is moving TFT to Unreal so the team can build better tools, reduce conflicts with League updates, and give the game more room to grow as a long-term standalone experience. So while Set 18 may not look like a dramatic reboot on day one, the move could shape the future of TFT for years.
TFT Is Moving to Unreal Engine With Set 18
Riot confirmed that TFT will officially move to Unreal Engine when Set 18 launches on August 12. Until now, TFT has been built on Hextech, the same technology foundation shared with League of Legends.
That shared setup made sense when TFT began as a mode connected closely to League, but the game has grown far beyond that. TFT now has its own ecosystem, cosmetics, mobile version, competitive scene, and design needs. Moving to Unreal gives Riot more freedom to build around TFT specifically, instead of constantly working within a shared League structure.
However, Riot is being careful not to oversell the immediate impact. The studio says Set 18 should feel similar to past TFT sets, and the engine migration is not being treated as a relaunch. Players should still recognize the game, its flow, and its core identity.
This Is Not TFT 2
One of the most important clarifications from Riot is that the Unreal Engine move does not mean TFT is becoming a sequel. It is not TFT 2, and Riot is not rebuilding the game into something completely different overnight.
In TFT’s case, Riot’s goal seems to be continuity first. The team wants the transition to feel stable for players while opening the door for more ambitious updates later.
In other words, the short-term goal is to make TFT work smoothly on Unreal. The long-term goal is to use Unreal to build features and improvements that were harder to create under the old setup.
Set 18 Will Have a Bigger First Download
One change players will notice right away is the file size. Riot says the initial Set 18 patch will be much larger than a regular TFT update because of the move to Unreal Engine.
Mobile players will also see the TFT app automatically replaced with the updated Unreal version. That should make the process smoother, but it also means mobile users may want to check available storage before the update arrives.
Settings Will Be Reset After the Migration
Another important change is that player settings will reset during the move to Unreal. Riot says preferred settings will return to their default state, which means players may need to manually adjust their setup again after the update.
Cosmetics themselves are not going away. Riot says cosmetics will be ported over to the new engine and appear in the updated Loadout. Players may simply need to reselect or refavorite parts of their setup after the migration.
Riot expects more bugs than usual
Riot is also being upfront about one of the biggest risks of the Unreal Engine move. The studio expects more bugs than usual during the early period of Set 18.
Because of that, Set 18 will have a longer PBE cycle than normal. The PBE period begins on July 14 and will run for four weeks, giving players more time to test the set and report issues before the full launch.
Riot says the engine switch should not directly affect game balance, but bugs can still influence the player experience.
TFT Is Getting a Dedicated Client in October
The Unreal Engine migration and the dedicated TFT client are not launching on the same day. When Set 18 arrives on August 12, TFT will move to Unreal, but the PC client will still remain in Hextech for a little longer.
Riot says the TFT-specific client is scheduled to arrive four patches later on October 9. That client will also receive an extended PBE period, which suggests Riot wants to take a careful approach instead of rushing every part of the transition at once.
RP, Currencies, and Cosmetics Will Carry Over
Players do not need to create a new account after the migration. Riot confirmed that TFT will continue using Riot accounts just like before.
RP will also remain shared across League and TFT, so players can still use it across both games. TFT-specific currencies will carry over as well, which should ease concerns about losing progress or purchases.
Cosmetics will also be moved into the new engine. The main difference is that players may need to check their updated Loadout and reset favorites after the migration.
Little Legends in ARAM Are Changing Long Term
There is also one notable change for League players who enjoy using Little Legends in ARAM. Existing Little Legends will still be supported as ARAM companions before the Unreal swap, and Riot plans to support new Little Legends across both ARAM and TFT for a while.
However, Riot says that long-term support for new Little Legends as ARAM companions will be discontinued as the team explores more Unreal options for TFT’s Tactician roster.
TFT’s New PC and Mobile Requirements
Riot says mobile minimum specifications will remain fairly similar overall, but support will be affected for iOS devices with 2GB of RAM and Android devices with 2GB or 3GB of RAM. Riot described these as a small portion of global devices with a TFT installed.
On PC, Riot lists the minimum requirements as Windows 10 version 19041 or newer, DirectX 11 with Feature Level 4.3, and Shader Model 5. For most current PC players, this should not be a massive jump, but older systems may need to be checked before Set 18 launches.
So while Riot says TFT will not feel different right away, this is still one of the most important updates the game has ever received. The Unreal Engine move is not a flashy reboot. It is the foundation for whatever TFT becomes next.
