All you do is download it from PlayStation Store then when it is done downloading it need to be installed then it can be opened when the game disc is in the ps3
Yes, you can use any addons that a full account can use. There is no limit.
At the Xbox market
You don't. PS3 downloads for the Call of Duty Black Ops DLCs must be purchased from the Playstation Store. The PS3 was designed not to allow the USB Drive to load Games and Add Ons so the Playstation Store could have exclusive rights to download sales. By the way Rezurrection is the correct spelling for the $15 DLC
No, not usually. Mostly, you need to own the core game. There are some episodes of games that you can play without owning the original, but they are separate games, not add-ons.
Playstations that are connected to the internet get game updates when the game is placed in the PS3. If you mean Add ons and not updates even free add ons must be gotten from the PlayStation Store.
PS3 = PlayStation Network Store. (Go to Game Add-ons --> Q-S --> SCIV) I am unsure about Xbox.
DLCs are for games and when they are out for PS3 game they can be found at the PlayStation Store under Add ons
Go into PLAYSTATION STORE and select game add-ons and there is an A-Z of games and all their add-ons like COD5/4 map packs LBP costumes etc...
For any PS3 game add ons you must get them from the Playstation Store on the Playstation Network
Besides downloading you do need to install many add ons and that may be your problem. On Rezurrection it took much longer to install than to download. I have not gotten the Just Cause 2 add ons, but all add ons must be dowmnloaded after purchase and then most must be installed.
Downloads on the PS3 for games and add ons must be purchased from the Playstation Store. You can not download elsewhere as they retain exclusive rights to provide game and add on downloads
Downloads for PS3 game add ons are best accomplished through the PlayStation Store after First Strike is released for the PS3
You don't computer game mods will not work on the PS3 and the PS3 USB port does not go to the games section of the PS3 hdd to allow uploading of games, add ons, or mods
OK what i know is that all you have to do (for PS3) is go to the PS3 store and look for add-ons (it'll be on the left) then search for what ever call of duty game you have, next click on the add-on then purchase. if its for X-box then sorry because i only have a PS3
To download on the PS3 for games and add ons you must go through the Playstation store. For Music and Videos there are more options like Netflix that you can join through your PS3
