Beach Buggy Racing 2 has asynchronous online multiplayer, which means that you play against avatars of other players (and other people play against your avatars). You also play against real players in leaderboard tournaments.
We are not bringing any other form of multiplayer to the mobile version.
Local split-screen multiplayer is a feature of our premium/console version of Beach Buggy Racing 2: Island Adventure with up to 4-8 players depending on the platform. On Steam PC, there is 4 player split-screen multiplayer with Remote Play Together.
