What do SINoALICE, the dark mobile fantasy battle RPG, and critical darling NieR: Automata have in common? Well, more than just highly stylized names—both titles are directed by the ever-entertaining (and utterly unpredictable) Yoko Taro and full of memorable characters and dramatic moments.

Last month, a crossover event brought the worlds of SINoALICE and NieR: Automata together. As reported by GameSpot, players who log into SINoALICE between July 16 and Aug. 6 will unlock Automata protagonist 2B for free. Act fast, because the event wraps up soon!

SinoAlice, a mobile RPG with gacha elements from the director of Nier Automata, has reached 1,000,000 players two weeks after its global release. The game also has a Nier Automata crossover event that runs from July 16 to August 6 and you can receive 2B from Nier Automata as a playable character just for logging in.

The event features a series of quests written by Yoko Taro–the director of SinoAlice and Nier Automata–and features machine lifeforms as enemies. You can also unlock A2 and Emil in The Puppets’ Feast Grimoire, the games’ loot box-type mechanic for unlocking gear.

SINoALICE’s twisted take on fairy tales is now available globally. The NieR: Automata event runs through Aug. 6. For more information, visit the official SINoALICE website and read GameSpot’s complete coverage here.
