How do you play Resident Evil 5 on two player on the PS3 I know how to get two players actually playing but the buy option for player 2 never shows up. And when you try to sign in it signs the 1st?

To play Resident Evil 5 in two-player mode on PS3, ensure that both players are signed into their own PSN accounts. Start the game and select "Co-op" mode from the main menu. If the buy option for player 2 isn't showing, try connecting both controllers and ensure the second controller is powered on and assigned to the second account. If issues persist, check the game settings or restart the console to refresh the controller connections.
