Well there were 3 total global events (that I knew of) during the time between NM and soon after the last update where everyone had to kill up to 80 million or something zombies within a few days to get a key, black box and some other trash rewards as per usual, but it was never that image. I would say it was probably that with maybe slightly less crappy rewards. :P
