Niantic Labs had tremendous success with Pokémon Go, which paired their expertise in building location-based augmented reality mobile experiences with a top-flight IP with a ravenous fan base. So, it stands to reason that we should expect a similar fan response to Harry Potter: Wizards Unite, an AR title set to launch in 2018, co-developed by Warner Bros. Interactive and its new sub brand Portkey Games.
Niantic building a Harry Potter game similar to Pokémon Go was rumoured last year, when the company noted that it had acquired the rights to the app. But the rumour was subsequently debunked, oddly enough, with the original article containing the information pulled from the web.
The app is now official, but the details are still scarce, with the launch timeframe of just sometime next year, but it sounds like there will be significant influence from the Niantic game Ingress, which allows players to roam the real world collecting power-ups, defending locations and exploring their environment.
The mechanics of Ingress would actually translate pretty well to the fictional Harry Potter universe, and seems almost ready-made for a fantasy spell casting coat of paint to replace its science-fiction special forces veneer. Also, like Pokémon Go, it could benefit from the location database built up by Ingress originally (and expanded by the Pokémon title) to incorporate real-world locations into the in-game experience.
Update: Here’s a link to the official announcement for Harry Potter: Wizards Unite.
