I am trying to get the Collector acheivement. I have gotten all the weapons exept the Frag grenade attachment and the Night vision upgrade, both of which your supposed to get from the 3rd JBA HQ mission. But when I load up this mission there are no stars by primary or any other objectives and when I beat it on perfect multiple times I still can't unlock these gadgets. is this a bug or what? Thanks for any info.

Most likely you missed several star objectives on previous missions (at least 5) to be missing those items. The only way to know is by playing through each mission and looking for any star objectives to show up in the OPSAT. Complete those and the items should unlock.

HERE is my list of objectives and where all the star objectives are located.

Note that items ARE NOT unlocked by SPECIFIC objectives. That is to say, they are unlocked IN ORDER. So if you skip an objective, that item will move down the list to the next star, that's why you haven't unlocked them.

OK, I tink i will just start a new game on easy and make sure I get all of those objectives. thanks for the help.

oh I see. I just went back and played kinshasa and got one of the star marked objectives, unlocked the frags, then loaded it up just to see if the star was there are not and it wasn't anymore. so ijust need to go load up all the missions until I see that star again then i will have it.
