The story
4X Studio was founded in 2002 as a subsidiary of 4X Technologies. After releasing only one game under that name, Iron Storm, it closed and later reformed by Roman Vincent and Yann Tambellini as Kylotonn in 2006.
In 2012, Kylotonn developed the Play All technology with Wizarbox and Darkworks.
In 2014, the studio launched the KT Racing label.
In 2015, the company opened a facility in Lyon, Kylotonn Racing Games.
In 2017, the company won the 2017 Ping Award for "Best Sports Game" for WRC 7.
On 2 October 2018, French publisher Nacon (formerly Bigben Interactive) announced that it had acquired Kylotonn. Kylotonn and Bigben had previously collaborated with each other since 2008.
Insolvency and financial difficulties
In February 2026, parent company Nacon filed for insolvency, after being unable to make repayments to bondholders. This caused three subsidiaries, including Kylotonn, to individually file for insolvency.
The French union STJV reported Nacon's intentions to continue with mass layoffs at the company, before postponing the meeting scheduled for the announcement. This followed the formation of a new team within Nacon made up of former Kylotonn employees, known as Grit Games, who hold the official license to develop games for the FIA World Rally Championship until 2032.
