Fanatical Men of War Assault Bundle leftover, good luck!
The bundle gave both a key for the game's special edition and a key for the upgrade pack DLC, so that's one too many for me ^^

NB: This is a DLC so it's not detected by SG, please make sure you don't own it before revealing the key: https://store.steampowered.com/app/63942/Men_of_War_Vietnam_Special_Edition_Upgrade_Pack/
