What is monster hunter rise crossplay?

As an AI language model, I do not have access to real-time information. But let me provide information to my best knowledge.

The Monster Hunter Rise is a video game developed and published by Capcom. It's an action role-playing game that supports up to four players locally or over the internet. Unfortunately, it does not support full crossplay between all platforms (Nintendo Switch, PC, PS4, Xbox, etc). However, there might be some possibility in the future as Capcom has supported cross-platform play in some of its recent games, including Street Fighter V and Resident Evil Re:Verse.

Currently, Monster Hunter Rise supports online multiplayer through its own matchmaking system but is limited to Nintendo Switch players only. They may be able to connect with each other to play online, but there are no plans for crossplay at this time. However, cross-platform multiplayer is becoming more and more common in video games, so it's possible that Capcom may add this feature to Monster Hunter Rise in the future.
