    Just a few tips to make sure you get this and don't disqualify you or your friends from this achievement
    -One player must have beaten the entire Co-op before and one player must have never done the tutorial.
    -The player who has never done the tutorial must never been in a chamber, the central hub is fine.
    -Single player does not affect this, so you can have played the whole single player and it won't affect this.
    -If you are going for other achievements, such as Friends list with benefits or other similiar co-op ones, skip the tutorial by pausing during the opening cutscene and returning to the hub.
    -This cannot be done split-screen, must be two players with Active X-box Live accounts
    -The only required chamber is the tutorial chamber where you acquire the gun and calibrate weight variances, which can really upset humans if you bring up :)

    Hope this helps.

    You must have completed the co-op campaign.

    You cannot get this achievement on split screen.

    You have to have them on your friends list.

    You can also create temporary accounts that get 1 month of free Xbox Live Gold and you can get this achievement with a friend.

    They need to generate a new Windows Live ID -- -- (I went with a generic, DKBOT e-mail address). Sign in with a new account on your Xbox. Attempt to sign-up for Xbox Live Gold, select the "Upgrade Later" option and sign-up under a Silver account. The next screen will offer you a free month of Xbox Live Gold with your new account and accept this offer.

    There you go, a free second account and you don't have to find a 48-hour code or attempt to track down a new friend who hasn't started the co-op.
