Nintendo has announced that Wii U exclusive Splatoon has passed one million sales worldwide, less than a month on from its release on 28 May.

The online shooter and new IP for Nintendo has proven a big success in all territories, remaining in the charts despite stiff competition from established franchise sequels like The Witcher 3: Wild Hunt and The Elder Scrolls Online.

A breakdown of the sales reveals that 476,000 digital and physical copies were sold in North America, over 230,000 across Europe, 368,000 in Japan, and 20,000 across Australia and New Zealand.

In a statement Nintendo of America president and COO Reggie Fils-Aime said: "Ever since Splatoon launched on May 29 in the United States, we've seen thousands of people go online to have fun in this colourful, chaotic competition.

"This milestone puts us in a nice position as we prepare to launch 11 more exclusive Wii U and Nintendo 3DS games before the end of the year, plus amiibo, digital offerings and games from our third-party partners."

Nintendo of Europe President Satoru Shibata adds: "We are pleased this new Wii U exclusive game is capturing the imagination of so many fans across Europe, and look forward to bringing more exclusive titles to both Wii U and Nintendo 3DS this year."

Nintendo's handling of the game has been commendable too, with a whole summer's worth of free new maps, weapons and gear being made available worldwide. Three new maps have been added to date with more expected – as well as new game modes - ahead of a major update in August.
