About Team Fusion Simulations

Team Fusion Simulations (TFS) is the international volunteer development group behind the continued life of IL-2 Sturmovik: Cliffs of Dover. The group began in 2012 as a community of modders who set out to repair and improve the original 2011 title after its developer, 1C:Maddox Games, stepped away from active support. In December 2016, 1C Game Studios and the renamed Team Fusion Simulations agreed to cooperate on future releases, granting TFS official access to the game's source code.

Cliffs of Dover is a Second World War combat flight simulator centred on the Battle of Britain in the summer of 1940. It is renowned for its detailed damage modelling — airframe, engine, cooling systems and control runs are simulated individually — and for its fully 3D, mouse-operable cockpits. The TFS-developed Blitz edition (December 2017) modernised and stabilised the original release, and the Desert Wings – Tobruk add-on (August 2020) extended the simulator to the Western Desert campaign over North Africa from 1940 to 1942, adding more than forty new flyable types and a 385 × 385 km North African map. Work continues today on the next add-on, Fortresses and Focke-Wulfs – Dieppe, as well as on a VR implementation, a TrueSky-based visual overhaul, and regular maintenance and improvement patches (47 as of May 2026) to the live game.

Please note that when Single Missions are updated by TFS it is not automatic that you will see the updated missions in your game immediately. This is because TFS will never delete any files that are in your "\Documents\1C SoftClub\il-2 sturmovik cliffs of dover" folder! To get the updated Single Missions you must delete the existing missions in "\Documents\1C SoftClub\il-2 sturmovik cliffs of dover\missions\Single" while the game is not running. Next time you start the game the updated Single Missions will be copied from the game's installation folder (...\Steam\steamapps\...) into "\Documents\1C SoftClub\il-2 sturmovik cliffs of dover\missions\Single" from where you then can play them.
