Wildy popular free-to-play RPGFinal Fantasy Brave Exviusis getting some brand-new content thanks to yet another crossover event, this time featuring an all-time classic: 1998 Playstation’s veteranXenogears, considered by many to beone of the best JRPG ever, is coming to the mobile game in a time-limited banner.

Final Fantasy Brave Exviushas enjoyed quite the success after being published in 2015, a product of Japanese video game giant Square Enix, famous not only for theFinal Fantasyseries but also for the critically acclaimedDragon QuestandKingdom Heartsfranchises.Brave Exviusis an all-mobile release available for iOS, Android, and Amazon Fire: a free-to-play role-playing game featuring elements from previous titles in the saga, where combat occurs in a turn-based fashion and the player’s characters launch attacks and special abilities via a simplified interface.

The newCelestial Machinerycrossover event has started February 10 and will last until February 23, allowing the players to summon characters Neo Vision Grahf and Neo Vision Id, in addition to free unit Fei and a free daily summon; moreover, a free weekly 10+1 summon will be available to everyone between February 10 and April 22. Dedicated players will note that this isn’t the first iteration of such an occurrence: a similar crossover happened in 2019, when the unlockables were Bart, Billy, Chu-Chu, Citan, Fei, Elly, Emeralda, Maria, and Rico.

The free-to-play title has featured a long and varied list of crossovers, including many featuring other blockbuster Square Enix titles such asOctopath TravelerandKingdom Hearts. While collaborations with other franchises are typical of this genre of games,Final Fantasy Brave Exviuswent so far as including pop music sensationAriana Grande in the gamein 2017.

Like many other successful free-to-play mobile games,Final Fantasy Brave Exviushas adopted the gacha model: a system in which players can unlock new characters, weapons or skins by pulling from a banner, investing game coins in a more or less randomly generated outcome, typically reflected in its rarity by a star rating. This very model allows the easy integration of crossover events in the games, which do much to increase longevity and keep content fresh.

The gacha mechanics, often subjects of criticism for their similarities to gambling, have nevertheless proved exceptionally popular in recent times, with games likeGenshin Impactrising to critical acclaim. The contrast cannot be greater withXenogearsitself, a game from another era with a veritable cult following, and aJRPG that desperately needs a reboot: a title from a time when the very idea of free-to-play games with microtransactions would have been difficult to even imagine.

Final Fantasy Brave Exviusis available on iOS, Android and Amazon Fire, while theeventCelestial Machinerywill run until February 23.
