Hell Let Loose

Hell Let Loose is a 2021 multiplayer tactical first-person shooter developed by Expression Games and Cover 6 Studios, and published by Team17. Players fight in iconic battles of the Western, North African and Eastern Fronts of World War II at the platoon level. The game was created and developed by Australian studio Black Matter, led by Maximilian Rea, who first announced it via a successful Kickstarter campaign in 2017 that raised a total of US$220,000. It was initially released for Microsoft Windows as an early access title on 6 June 2019, and fully released two years later in July 2021. It was later released for PlayStation 5 and Xbox Series X/S on 5 October 2021. In January 2022, Black Matter sold the game to its publisher Team17 for £31 million with the potential addition of £15 million based on the game's performance. Development was handed to Team17 shortly after December 2022, who then founded Cover 6 Studios in the beginning months of 2023 to work on development and potentially on the next game in the series. In April 2023, Team17 contracted the UK studio Expression Games to also continue development of the game. On 20 August 2025, a new Hell Let Loose title was announced. Titled Hell Let Loose: Vietnam, the game is set during the Vietnam War, with two primary factions―the North Vietnamese and American―fighting in the Vietnam War between 1965 and 1973.
