Is there an easy way to see how much bandwidth you are using for your phone/console for...

There is no way a simple DDoS attack used that much of your bandwidth...

For further reference, your own personal bandwidth may be verified at:

This will at least give you an idea of how much bandwidth is available to your X-Box console, so that you can be your own judge whether you have enough for certain activities using X-Box Live!

Go to My Games & Apps > Games and highlight Evil Within, press Menu on it (equivalent of 360's Start) and select Manage Game. That will show you the total file size.

To see how much bandwidth the console is using, go to Settings>Network>Bandwidth Usage and from those two bits of information you should find what you're looking for.

Let us know how you get on.

For reference , it will access the internet to update friends list and the like , but shouldn't be "chewing up bandwidth" ....maybe you should see how much it is really using...

Depends how much you played ofcourse. If your cap is somewhere in the 250GB range, then just play away. It doesnt use THAT much bandwidth, believe it or not.
