Cross-platform play

In video games with online gaming functionality, also called cross-compatible play, cross-platform play, crossplay, or cross-play describes the ability of players using different video game hardware to play with each other simultaneously. It is commonly applied to the ability for players using a game on a specific video game console to play alongside a player on a different hardware platform such as another console or a computer. A related concept is cross-save, where the player's progress in a game is stored in separate servers, and can be continued in the game but on a different hardware platform.

Cross-play is related to but distinct from the notions of cross-platform development, cross-platform releases, cross-buy, and cross-platform save game cloud synchronisation.

Cross-platform play, while technically feasible with today's computer hardware, generally is impeded by two factors. One factor is the difference in control schemes between personal computers and consoles, with the keyboard-and-mouse controls typically giving computer players an advantage that cannot be easily remedied. The second factor relates to the closed online services used on consoles that are designed to provide a safe and consistent environment for its players that require the businesses' cooperation to open up for cross-platform play. Up through September 2018, Sony Interactive Entertainment had restricted PlayStation 4 cross-platform play with other consoles, creating a rift between players of popular games like Rocket League and Fortnite Battle Royale. In September 2018, Sony changed their stance, and had opened up beta-testing for Fortnite cross-platform play. Sony officially stated it will allow any developers to support cross-platform play in October 2019.
