You can now see all the solutions we have getting xbox 360 achievements on their [own page=solutions.aspx]. You can also see any recent guides added on someone's profile page and click the More button to see them all.
And there's now a new badge for completion percentage. This shows the number of gamerpoints you have earned compared to the total gamerpoints in all the games you have. A high percentage tied with a high TA means you're a proper hardcore gamer!
Just how good are you?
