進撃の巨人 in HITA is an Android-based action game developed by TSおおいた. It is a GPS location-based game where the player uses their smartphone to traverse the real-world environment and fight against the giants that have invaded Hita City in Oita Prefecture. The game offers a unique experience where players can explore the city while engaging in the subjugation of giants. The game features an AR spot where players can take photos of the giants they have defeated. The game is free to play and can be played in the area-free mode, allowing players to play from anywhere in Japan. However, to use the specified AR, local GPS information in the Hita City area is required. The game is only optimized for Android 8 and above and requires a network environment (Wi-Fi/4G/5G) and GPS/location information service. It is not applicable to root devices. We recommend using a device with 2GB or more RAM to play the game optimally.
