Bandai Namco itself has confirmed that it will be shutting down its mobile game Naruto Ultimate Ninja Blazing starting February 8th.
The free "shinobi formation battle" game features combat that revolves around the players' position on the screen. Players move characters around the screen, and the characters will then attack any and all enemies within a circular range. If enemies are within the same range as an ally, the characters will use a combo attack.
Naruto Ultimate Ninja Blazing was released in Japan in 2016, and received an English translation later that same year.
