You will need something called a HD PVR. I would recommend a Tristar mx hd pvr to you. I just wrote to another yahoo person asking about this just like you.
Here is a link to the same yahoo answer. It explains in detail how to record nazi zombie gameplya from a pls3. Although you will not be able to record it like in black ops, because black ops has a built in feature to do it that is limited to 30 seconds or so, but you can learn how to record.
So here ya go, good luck kido Im not sure if I can give you the direct link to the yahoo answer links without spamming so I suggest you search with quotes for "How do I record game play on my xbox.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
