It looks like one of the most anticipated Pokémon Go features is finally on its way. In a series of tweets, developer Niantic teased player-versus-player battles. It’s a feature the developer has promised for some time, and it’s an integral part of the traditional Pokémon experience. In fact, battles were part of the initial pitch when Pokémon Go was first announced back in 2015. But, much like trading, battles took longer than anticipated to actually implement in the game. Unfortunately, right now, we don’t know anything about how the feature will work, but Niantic does say that trainer battles will be coming “soon.”
