My self-made infection-free zone flag expansion pack contains the flags of real-life countries and regions, as well as the historical flags of Portugal China and Spain. I have also prepared exclusive flag packs for players who like to play The Uncharted Waters Online and World of Warcraft.
You can download this pack and unzip files to the Infection Free Zone_Data\StreamingAssets\Emblem\Logo folder and use them as emblems in the game.
