What is Cross-Platform Gaming?
When it comes to video games, cross-platform play, or simply crossplay, means the ability to play an online multiplayer game not only together with friends who are playing on the same hardware platform, like a particular console or PC, but also alongside people using different hardware. That makes it possible, that a player running a PC can play together and party up with friends using a XBox One or PS4 in games like Fortnite.
