Square Enix has recently announced its own AR exploration game called Dragon Quest Walk. The game will include challenges to visit real-world locations in order to complete quests, much like the popular game Pokemon GO. Details of the gameplay isn't clear but it is speculated that the game will feature a mix of battling monsters in turn-based combat and decorating your own virtual room with items collected through challenges and quests.
Beta test on the 11 June 2019 is open for registration here, with 20,000 places split evenly between iOS and Android users. Quests are oriented around local landmarks but localization outside of Japan has yet to be confirmed.
