im not sure if it has anything to do with the zombies... but i found some random signs around the map. the ones i found so far say: GER, ENG, and FRA. i personally believe that the others i havent found will say AME, ITA and RUS. because the countries on the european front are GER-many, ENG-land, FRA-nce, and for the ones i havent found... AME-rica, ITA-ly and RUS-sia. if any other people find them and have any clues on what they truly mean then plz inform me on the news.
