Shogun 2 and Steam activation. I’ve never used Steam before…
In order to play Total War: SHOGUN 2 you will need to authenticate your copy of the game by registering it online with the free STEAM gaming service.
You only need to connect to the internet once to do this and the installer will take you through the process when you put the Total War: SHOGUN 2 disc in your drive.
If you don’t already have a free Steam account, you will need to create one, and this will give you access to some features described in the ‘But what is Steamworks?’ section.
The Total War: SHOGUN 2 game activation is subject to your acceptance of the Steam Subscriber Agreement (“SSA”).
Please see http://www.steampowered.com/agreement to view the SSA prior to purchase. If you do not agree with the provisions of the SSA, you should return the game unopened to your retailer in accordance with their return policy.
