I have a question about something

There's an Assault rifle in Pod A at the beginning of the area where you fight the Brute Husks - the control panel opens the pod up.

I remember that, so what happened?

Never mind, figured it out.

with the xbox one all game saves are loaded to the cloud through your account even if you don't have xbox live gold so when you download your profile to any xbox including if you get the new xbox one x then any digital games you own will show up and game
saves will be synched with the cloud game saves when you start up the game.

It depends on what you're trying to pay. If it's a subscription, you would need to use a credit card/Paypal.
