Spartan Ops, episode KEY. Chapter HAMMER crash. I have reported this issue so many times and so long time, has it been 1 year? Nothing been done, crasching game over and over again. This is the last chapter of all the others. I down loaded game to try again to day, oh no, same issue, crasching game. And the new thing is that all spartan ops difficulty levels are erased! You know what? I do not care, why shoud i give so much time and effort to you and your games! i leave it there, no more! Enough is enough! Goodbye!!
