Back to Karkand

Ai pra quem comprou o DLC de BF3 e não sabe como ativá-lo seja no pc ou no PS3. Aqui vão os tutoriais:
PC:
1. Confirm if you are entitled to Back to Karkand at no extra charge
If you are a Limited Edition owner, you will get the Back to Karkand expansion pack at no extra charge. An easy way to check if you are entitled to this is to log in to Battlelog as usual. If you are a Limited Edition user, you should see a banner on the left hand side that says you own Back to Karkand and are ready to play it. You can skip to step 4 below.

2. Make sure you have downloaded the latest Battlefield 3 update
If you did not download the Battlefield 3 update we released December 6th, do so now. Either check the download progress bar within your Origin application to verify that the latest update is downloading and installing, or use the download manager in Battlelog to make sure your game is updated to the latest version. Without this step, you will not be able to play Back to Karkand, but if you have played Battlefield 3 the last week, chances are you are already properly updated.

3. Buy Back to Karkand/Enter your boxed code

You can buy Back to Karkand for $14.99 (£11.99/149 SEK/14.99 euro) from the Origin web store. Or, if you prefer, you can buy it from within your Origin application itself. Click "Battlefield 3" inside Origin to see Back to Karkand, or search for Back to Karkand in the search field within your Origin application.

If you bought the code-in-a-box version of Back to Karkand (a physical box for PC with a download code inside), start your Origin application, click the cog icon, select “redeem code” and enter the code found in your box. This will start the download of Back to Karkand.

4. Find your new maps

The four new Back to Karkand maps (Strike at Karkand, Wake Island, Sharqi Peninsula, and Gulf of Oman) will appear in the server browser, just like any other map. You will also be able to filter for only Back to Karkand maps by clicking the Back to Karkand logo in the top left corner of the server browser’s filter settings. Servers running Back to Karkand maps will have a small brown "B2K" icon in the server list to help you identify them.

5. Go back to Karkand!

Jump into the game and enjoy your new content! You can find information on your new Back to Karkand Assignments in the "Assignments" tab on your stats page in Battlelog, and your profile will have the new "B2K" icon to verify that you have Back to Karkand.

Q: What happens if I try to join a game with Back to Karkand maps, and I haven't bought Back to Karkand?
A: You will see a message warning you that you need Back to Karkand. See image below. You can still join a server that has Back to Karkand maps, but once a Back to Karkand map goes into play, you will be returned to Battlelog.
