Quirky team-based Wii U shooter Splatoon has sold 1.6 million unites worldwide, Nintendo has revealed.

In an earnings report for April to June 2015, the platform holder said the game "enjoyed a good start" and the Nintendo will "strive to further enhance the sales towards the year-end season."

According to the information provided, sales of Splatoon in Japan reached 490,000 units, while the rest of the world accounted for 1.1 million units.

"With respect to Wii U, Splatoon, which was released globally in May and gathered attention, marked 1.62 million units in sales and contributed to vitalizing the Wii U platform," Nintendo said in a statement.

In late June 2015, Nintendo confirmed Splatoon had some over one million copies worldwide.

"Since Splatoon launched on May 29, it has been great to see so many players competing in online matches," said Nintendo of Europe president Satoru Shibata at the time.

"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."

GameSpot's Splatoon review described the game as "the antithesis to the modern shooter," but added that it "primarily deserves recognition for what it is, not what it isn't."

"It's a wonderful game with charm and inventive ideas that work and pave the way for new experiences in an otherwise stale category of games."
