Disappointingly, GTA 5 isn't a cross-platform game. While most games that have any semblance of multiplayer capability these days are cross-platform, GTA 5 isn't one of them. In other words, if you're playing GTA 5 on a PS4, you can't play with other GTA 5 players that are gaming on the PC or Xbox. In fact, you wouldn't be able to play GTA 5 across different generations of the same console. If you're playing GTA 5 on PS4, you can't join GTA 5 online servers that are hosted for players on the PS5. As of now, it's yet to be seen when Rockstar Games will finally allow cross-play for Grand Theft Auto V. This is despite fans clamoring for this addition for years now.
