Monster Hunter 4 Ultimate, Capcom’s newest entrant in its flagship action-RPG series, has now shipped more than three million copies worldwide.

Released on Friday February 13 in North America and Europe, the game appears to have made an immediate impact, entering the UK all-format game charts at fourth. Sales were spurred on by the release of Nintendo’s New 3DS handheld, which also launched across the west on Friday.

Capcom's latest action-RPG first launched in Japan on October 11, under the slightly amended name Monster Hunter 4G. Both Ultimate and 4G are the same game overall; an upgrade of the original Monster Hunter 4 that shipped in 2013.

While the original managed to surpass four million sales in about six months, Ultimate/4G is threatening to eclipse that feat already. On Monday, the publisher wrote in a notice to investors that “the resulting popularity of Monster Hunter 4G/Ultimate has propelled worldwide sales to more than 3 million units globally.”

Since the first Monster Hunter game made its debut in 2004, the series has steadily grown into what Capcom calls a “mega-hit,” now with cumulative sales of more than 32 million units worldwide.
