I used to take screenshots from my pc when playing MUA all the time. I would love to do this with my 360. How could I do this?
You do it the same way you do it with any other console. You buy one of those cards, stick it in the computer, then plug your console into it.
It should be possible to take screenshots with a 360, without a cam. On google there are many screenies of mua from the 360, just keep messing around, if you don't find the screenshooting trick then either search google or use a HD Cam, results are clear.
