Re: How can I play battlefield 2042 on PC with my PS4 friends?

The cross play is limited to the following

xbox one (and xbox one x)  & PS4 (and ps4 pro)

xbox series s / x & PS5 & PC.

So your friend would need a next gen console in order to play. The reason is because the previous generation of consoles are limiting, so they have different version of the game which has a max of 64 players and does not include the largest map sizes.

There is no equivalent on the PC to play with xbox one & PS4 players.
