Surviving a Zombie Apocalypse my own way

It didn't start with a loud bang, or a virus gone rampant, it just.....happened. at first only a few were spotted at any given time but them these small groups began to grow in number as people started to vanish from their homes. Soon enough hordes began showing up and people began to abandon homes and business as life became harder. eventually then military tried creating living biological weapons to help combat the growing threat but by then the hordes were too big to combat normally. Decades pass as people learn to live and survive, even the bio weapons integrated into human society and created their own towns. Will you be human, or bio weapon and above all, will you survive.
