right i want to start of by saying that halo 4 is the best ever game i have played for a long long time and i dont know where to post this but i need to say because it has really affected my game and i dont know what to do know .
i started to play the campaign on xbox 360 and i started it on legendary i got to the leven infinity and saved and quit ,when i started to play it on saturday 17th november i got the welcome screen that i got when i first played halo when i got to the campaine bit it told me i had not completed any levels and they all had a padlock beside themand told me i had not done any ,now up to then i had completed up to the infinity on co-op and solo but nothing was showing i had done anything but on my service record it said i had done 5 levels on legendary had the 10g achievments for each level so i just went to resume campaign which took me to where id saved on infinity i completed the whole game today and got no achievment for completion but i did get the 10 g for each level but got the challenge for completing the campaign on legendary but no gamerscore achievments ,it then told me i had not done level 6 which i had done the day b4 but anyway i done it got the achievment for completing level 6 on any difficulty (i done all on legendary) . no achievments for completing the story on any.my service record tells me ive done all 9 on legendary ive spent 1 day 1 hour and 39 mins on it but no completion achiements and i still have a padlock on dawn,requiem and forerunner although ive done them.
please is there anything you can do as i dont want to do the whole thing again i have achiements for all the single levels but still no completion ones ,i even done the last one again after level 6 but nothing ,and also got the campaign challenge for legendary completion.
