GMS will soon have a crossover event with Attack on Titan, similar to the Sword Art Online Crossover. It will have a themed Dungeon or Event where over 20 exclusive items such as medals and consumables can be obtained similar to the Sword Art Online Crossover. This crossover is mostly likely to start during the end of January.
You will be able to play as the characters from Attack on Titans like you could during the Sword Art Online Crossover. You will also be able to embark on an episodic play where you escape from the Titan invasion, join the Cadet Corps and master the omni-directional mobility gear before you join the defense of Wall Rose during a fierce final stand. Prove yourself in battle and you’ll earn rewards such as medals and totems.
This crossover will include special Cash Shop items such as Dressing up as a member of the Cadet Corps, complete with your own omni-directional mobility gear. Get hats that make you look like Eren, Mikasa, Armin, or Levi. There are also multiple accessories and chairs! There will also be face cosmetics that will transform your face into the characters from Attack on Titan. There will be 2 titan cosmetic rings, where one is for your chat bubble and the other is for your IGN.
