Q: What all do I need? I got the Core System.
A: You need a wireless router, which you can buy at any gaming store or electronic store, to connect to your internet connection. If you dont have wireless than you need a internet cable connecting your xbox to the wall jack. That is the first step. Second, you need to buy a subscription card at the store. There are different types (2 months, 6 months, 1 year...etc). Then you are good to go. You just need to click the center x on the controller, go to the dashboard and look for the xbox live setup.
