You know how Sony is adamant about not allowing cross-platform play between PlayStation 4, Switch and Xbox One? Well, something interesting happened in Epic Games' Fortnite over the weekend: Xbox players were found in a handful PlayStation Battle Royale matches. A Reddit user noticed that someone in his PS4 game had a space in their handle (something allowed in Xbox Gamertags, but not on PS4), and then the thread picked up to include further examples like a father and son playing together on disparate consoles. A Twitch stream with video proof is embedded below. Curious, indeed.
