Yesterday, many fans were surprised to see the first look at Pokémon Go at SXSW. This short video from “The Future of AR is Already in Your Pocket” panel at SXSW Gaming, which seems to have audio problems, shows for the first time a look at the gameplay. For some users, the video of Pokémon GO is a tech demo or prototype.
If you have doubts about the legitimacy of this video, people on YouTube and Reddit posted a picture and video of John Hanke, CEO of Pokémon GO developer Niantic, demoing the app.
For people having problems listening, the following transcript from FevGames.net was made available: “They’re distributed all around the world. Pokémon have different habitats, so some Pokémon like water, some like mountains. They live in the places they ought to live, which means that you will have to go to a wide variety of places to find them all. This encounter I’m gonna show you is also the first time this has been shown. You’ll get notified that you’ve encountered a Pokémon, and you can capture it with your Poke ball, so you toss Poké balls to capture it. It got away, so my throw wasn’t good enough or my ball wasn’t strong enough. So we’re gonna go for a more powerful Poké ball. So he goes into my Pokédex, and there’s other stuff you can do…”
One interesting detail about Pokémon GO is that it makes use of data from the Ingress app.
