I need help getting 80% on all missions and all tactical challenges .

 

the link you provided apparently already has 80% mate.

 

So if I load this gamesave it will just unlock ? Thanks once again and sorry for all the newb question I am new to this.

 

You have to get a save off your own hard drive or memory unit to get your unique IDs for your gamertag and xbox save device. Then you have to rehash and resign those IDs to the save you downloaded, then move the save to your xbox. Should be in tutorial.

 

Thanks guys of anybody here can walk me through it on xbl party chat that would be awesome if not thanks anyway. Is it safe to gamesave? Safer then modding gamerscore?

 

I think I did it right loaded save but 80% achievement did not pop?
