The King of Fighters All Star

The King of Fighters: All Star is a free to play, mobile RPG game released for iOS and Android, developed by a South Korean gaming company Netmarble authorized by SNK. The game brings together all the characters of the KOF series up to The King of Fighters XIV.

While including KOF series fighters, the game also includes limited crossover events with other franchises and companies. Most notable crossovers have been Gin Tama, Samurai Shodown and upcoming Tekken. In addition to crossovers, the game also holds special events that introduces fighters with holiday themes and genderbent characters.

Release History
The game initially released in Japan in July 26, 2018.

After high demand from South Korea, the game was released there in May 9, 2019 having gone through tests at events there since the end of 2018 and holding special venues for promotion.

It has been announced from Netmarble that the game will be released in the Americas and Europe by October 22, 2019 with pre-registering being available until then.

Features
While including all fighters from the main KOF series, the game implements a gacha system where certain characters are only available for a limted time. These "festa" characters are only obtainable through summons and not by regular unlocking.

Another feature is the battle card system, where certain special moves are unlocked by equipping a matching battle card suited for the specific fighter.
