This does not give any perks, as it is a skin. However, it's good for all the people who like Attack on Titan.
Like the Sunray Buster and the Council it has a custom stat of: Titans Killed: 1337.
It is 200 Robux [R$], or 6,000 Tickets [TIX]
You must close the game and come back, switching floors does not load it into your inventory.
