Does Cuphead on Nintendo Switch support cross-platform play?

Originally released in 2017 for the PC and Xbox One platforms, Cuphead is a 2-D run-and-gun style shooter with an old fashioned twist. Drawn using the style of cartoons from the 1930's, the game follows the tale of Cuphead and Mugman after they rack-up a bill with the Devil at his casino. In order to repay their debt, they are forced to defeat numerous bosses to gain their freedom again.

The Nintendo Switch release of Cuphead also brings with it a whole host of free DLC – not just for the Switch, but for the PC/Xbox versions as well.

• The ability to play as Mugman from the start of the single player adventure.
• Fully animated cut scenes.
• Localisation in numerous European languages as well as Brazilian Portuguese, Simplified Chinese, Korean and Japanese – some of the Boss & Level title lettering has also been modified to better represent the language being used.
• Tons of brand new animations and never seen before art.

This is just speculation at the moment, but any cross-platform play in Cuphead will probably work like Minecraft currently works on the Nintendo Switch. A multi-player option has been added to that game so that the player can access their Microsoft Account and also share their Minecraft World(s) with players using Microsoft's Xbox Live service. Of course, in order to play online on the Switch, that requires a Nintendo Switch Online Account.
