Once u have downloaded them just go to the game and it should be in ts slot or completely new
yes all you need to do is hook your xbox 360 to the internet.
Yes definitely as long as its on your xbox you can play it on or off xbox live.
go to bungie and download the map WHILE YOU ARE SIGNED IN TO BUNGIE.NET and you will get a message after the download on the computer that it will be downloaded when you are connected to xbox live and in halo reach.
yes, you can play DLC that was downloaded on a Xbox LIVE profile and play it on a non Xbox LIVE profile
Jtag is a mod for the Xbox 360 which allows you to play downloaded games. You could play xbox live with this but you will get caught and banned (xbox and gamertag ban).
No. Not games bought from a shop. Only games downloaded from Xbox Live.
yes if it is already downloaded
first of all you cant transfer downloaded items that have cost money aka Microsoft points. If you somehow do transfer it though i don't believe you have to be online to play it if is already downloaded onto your hard drive.
Not if your game disc is not in that Xbox 360 or if the maps need to be downloaded to it. I think what you want to know is do you need your own copy of the DLC Zombie Maps or if you can somehow use those that are on someone else's Xbox 360 while you are playing online with them and you can not. You need to have the map in your harddrive or on your game disc to play it.
no
In order to play a game that you have downloaded and burned to disc on an xbox 360 you have to mod your xbox. If you mod your xbox and log on to xbox live you will be banned.
Go to the "Games Library" section on your xbox dashboard. You can also get to it from the xbox guide by going to the left, then down to games library.
