I have been through the camapign a couple of times. First on hard then on the lower levels to clean up any missed secondary objectives. I have tracked each of them and have finished all levels having completed all the secondary objectives. Still the Hard Boiled Trophy will not show.... what can I do?
The only thing I can think of was one time on one of the levels at the end on hard, I completed it and just before the game was to issue the XP on the summary page, the game crashed and exited to the Sony XMB. I had to replay the level because the progress I had did not save. This is the only time something like that has happened but I fear it could have corrupted my game save. because from time to time when i finish a level my XP does not increment to the total.
One of the missions has three separate objectives. You need to play that level three different times and beat each of the different ways to win it.
