Small zombie attacks have occured in the past, although no full-scale apocalypse has ever happened. it is likely, however, that a zombie apocalypse will occur within the next 2-10 years, so be prepared! More info can be found aroud the internet, and in Max Brook's book, The Zombie Survival Guide.
who knows i maybe but maybe not but lets hope its not real like on resident evil and left 4 dead.
