It says 8/8, but not on Legendary. I beat the game on Normal first and then went back and played it on Legendary...gave me the achievement on XBox Live but in game it still says I haven't beaten four campaign chapters on Legendary solo. I'll probably just get the advice that I have to go back and re-play the chapters, but damn...

This seems like an awful glitch. Legendary is a pain in my rear to play and I completed all levels on Legendary (Xbox live achievements say so) but the game doesn't recognize it? And I was logged in? Shady...
