Doesnt cost anything. There are 2 discs, one for single player and the other for multiplayer. But, if you buy BF3 used, you need to buy the multiplayer pass.
It comes with an online pass, which you need to enter before you will be able to go online. The online pass is included in the game and will allow you to play online for free. However, if you have bought the game second hand, the online pass code might already have been used, or if you loose it. If this happens, then you will have to purchase an online pass from the x box live store or the play station store. It costs 800 Microsoft points or 拢6 ($10)How much does it cost to play battlefield 3 online?
If you buy on the PC or PS3, it's the cost of the game plus your internet connection. For the 360 it's game plus connection plus LIVE costs. If you buy used, you have to buy a $10 pass to play online.
Unless you are using xbox live, which you pay for already, it is free. I have yet to see an FPS that charges you to play online like an MMO.How much does it cost to play battlefield 3 online?
well if you buy the right game copy it comes with a free online pass to play. idk if they still sell em or not though. but ive heard its around 10 bucks. an no you dont need a different disc to play.
its free unless your on Xbox 360 because you have to play for live



battlefield itself is free to play once you have brought it
Well, It's free to play online if you play it on PC. As far as Xbox 360 or PS3? I have no idea.
