Hello friends, I have brought a new COD: Black Ops yesterday and it worked extremely well with my system .It is essentially a cool game to have. I like all its characteristics and I am so much involved in this game that I am incessantly playing the game since yesterday. On playing the game I establish out that I wasn't able to save the game for all the maps that I finished. This has occurred twice and once more and again I have to start from the beginning which is quite pitiable. So please can someone help me to discover out how can I save the game.
