Hot-seat play refers to multiple users acting on the same single saved game at the same computer. To initiate this, the user should first create a new game as normal. Once this has been done, to add new managers, either select ‘Yes’ if/when prompted, or select ‘Add New User’ from the ‘Options’ Menu. Once you’re happy with the number of users entered, play as ‘normal’. When one user has completed their tasks for the day and has clicked ‘Continue’, the game will then move onto the next user. When all users have clicked ‘Continue’, the game will progress.
Network play allows the user to play Football Manager™ 2011 against other humans over either a local area network or the internet. You can either be the host of such a saved game, or merely join a saved game hosted by another user.

To start a network game as the host, create a new saved game as has been described in this manual. Make sure the ‘Run as Server’ box is ticked in the ‘Preferences’ – this will allow other users to join your saved game. Once the game has been set up and you have chosen a team to manage, you are in a position to host a network game. From the ‘’FM’ menu, go to the ‘Game Status’ screen and note the ‘Server IP Address’. You will need to provide this to anyone you intend to allow into your network game.
If you are joining a network game, all you need is the IP address from the host. From the Main Menu, select ‘Join Network Game’ and then select a server. If no servers exist or the server you wish to join isn’t there, enter the IP address from the ‘Join Other Server’ option. You should join/re-join the network saved game.
