No. As the online multiplayer services for this title have been shut down, the CD key is not required to enjoy the Giveaway version of World in Conflict (December 2017). That said, the solo features of the game are available and you can still enjoy the Local Multiplayer mode. If you have any other questions, do not hesitate to contact us.
To play on a local network, follow the steps below: - Launch the game and select Multiplayer. - At this point, you might receive a notification regarding a CD Key. Please ignore and close it. - Then, select Local Network. - Once in the Local Network mode, you can either create a server or join one. To create a server, simply click on Create Server and choose your preferred settings. To join a server, either select a server in the list or click on Connect to IP. After adding the IP Address of the server, his port and the optional password (provided by another player), you should be able to play together. To find your PC address IP, please have a look at this official Microsoft article. Please note that it will only work if both users are connected on the same network.
