Is there a way to exit a multiplayer game of BF3 on the PS3 while waiting for the next match to start? I've tried the Start and Circle buttons but neither does anything. I know you can exit with the PS button, but I would prefer another way.
Correct, you can hit the PS button to exit, but that's it. Xbox users can hit the Xbox button.
For consoles, this has been a heavily requested feature for multiple versions of the franchise, but a proper way to exit between rounds has never been provided.
PC users can force the game closed, or hit ESC after the stats presentation to get an "exit game" prompt.
I havent tried this myself because i'm on wireless, but if you're using a wired internet connection you could try pulling it out when you're on the end of round screen. If you're disconnected it should exit you to the main menu saying you've 'lost connection to the server' and since you're between games it shouldn't affect your stats because you haven't quit a game...
