I was f3ing in flourite and I saw this group of zombies that looked like it was impossible for them to stay still, they were running every where! they didnt seem to be chasing anything in particular, but they seemed to be 'infecting' people, and you would see people going ofline then coming back on as zombies, it clogged up flourite and you had this huge tsunami of zombies suddenly run across were you were rping xD
