It would all depend on how you want to do it. For example if its for Halo 2 their are really only two options. One is that you play games with me and hope I get something otherwise you would need a capture card and be able to record your screen and then I could input some of my footage of you and make a video from that. Now if it is a game that allows spectators like Socom or Rainbow six that would be much easier. Take your pick, Im always looking for more videos to do.
