The Resident Evil series has sold more than 50 million units since its 1996 launch.
A little over 48 hours after its release, Resident Evil 6 has shipped more than 4.5 million copies to retailers worldwide. According to Capcom, this is the publisher's biggest initial shipment for any game in its history. Though the number of copies shipped doesn't equal the number of copies sold, this indicates that Resident Evil 6 is on its way to becoming one of Capcom's best-selling titles ever.
Capcom also revealed that the Resident Evil series has sold more than 50 million units since its launch in 1996. That's not included the sales numbers for RE6, which Capcom has not yet revealed, though we can probably expect a few million more units to be added to that total thanks to the latest zombie-killing entry in the series.
Resident Evil 6 launched to less-than-stellar reviews, but that doesn't seem to be having any effect on retailers' demand for the game. We'll know more once RE6's initial sales numbers are released, but it appears that it's on track to become another highly successful entry in the series.
