For years and years, Nintendo refused to make smartphone games. But that changed, with Nintendo releasing titles like Super Mario Run, Animal Crossing: Pocket Camp, and Fire Emblem Heroes to some success. Earlier this year, Nintendo announced that new Mario Kart game, Mario Kart Tour, is on the way to smartphones. And now, Nintendo has announced yet another smartphone game: an action RPG called Dragalia Lost.

Jointly developed by Nintendo and Rage of Bahamut studio Cygames, Dragalia Lost is described as a "new gaming experience with worldwide appeal." The game will launch first this summer in Japan, Taiwan, Hong Kong, and Macau, before coming to North America and Europe later.

Additionally, Nintendo has purchased 5 percent of Cygames' outstanding stock as part of this deal. Specific financial terms of the deal were not disclosed.

In December last year, a report said Nintendo failed to development smartphone games fast enough to meet demand and was trying to partner with new companies to catch up. The report claimed Nintendo spoke with Puzzle & Dragons developer GungHo about a potential partnership, though at the time there was no mention of Cygames being in the mix.

Nintendo is already working with DeNA on mobile games, and Nintendo owns a 10 percent stake in that studio. As it happens, DeNA owns more than 20 percent of Cygames, so all three companies--Nintendo, DeNA, and Cygames--are linked to an extent.

We don't know anything more about Dragalia Lost at this point, but keep checking back with GameSpot for more on title as we learn it.
