Seems that Microsoft heard about some naughty Gears of War 2 players who have used an unauthorized hack to get some Gears 2 achievements. Now those people can be shocked to see all of their achievement points reset to ZERO next time they log in.  Thats sticking it to cheaters!  Take away their worth absolutely nothing points, just so they can hack those same points back onto their profile.  Thanks great overseers of Xbox Live, your logic never ceases to amaze.  Now, don't worry your lame Avatar The Last Air Bender and King Kong achievement points are safe.
