Arslan: The Warriors of Legend (Arslan Senki x Musou in Japan) and Attack on Titan (working title) are currently being developed by Omega Force, the same team behind the classic Dynasty Warriors, Samurai Warriors and Warriors Orochi series.
The game will be released for the PlayStation 4, PlayStation 3 and the Xbox One. It will be available in Japan on October 1, 2015, and in the West in early 2016.
No gameplay footage can be seen on the game's teaser trailer below, but it shows a glimpse of the all-familiar gore seen in the anime. The English version of the game will be released for the PS4, PS3 and the PlayStation Vita in early 2016.
