The CFS3 Nationality Expansion Kit (NEK) ~ Redux Edition adds 14 nationalities to CFS3 in a standardized format along with 40 new pilot biographies, 22 repainted pilot models, medal images for the Royal Navy, Free France, Italy, Japan, Russian & the US Navy as well as several other support files. The new nationalities are used by various add-on aircraft, and missions, in the Quick Combat, Single Mission and Multiplayer environments. The new nationalities can also be used to develop modified campaigns. The NEK corrects some errors in the stock files which control the cutscenes and user interface (UI) for more reliable operation; plus, it adds support for aircraft and vehicle spawning over previously undefined areas of the CFS3 map such as Italy. Finally, for extra convenience, the NEK now includes the "RAF Country Switcher" (cswap.exe) by Charles Simpson and Martin Wright.

The Redux Edition of the NEK supercedes all previous editions and parts; the old version and parts are no longer supported. It is safe to install the Redux Edition over top of the previous versions. Optional Voice Pack and Advanced Animation installers, designed for the Redux Edtion, are available as well.

Follow the steps in the NEK Installation document to get started.
