Starcraft 2 Achievments

[jefe323]

quick question:

just finished the single player campaign on normal and i would like to get the rest of the achievements/portraits for hard/brutal mode. do i have to completely restart the single player or can i redo the missions one by one on the different difficulties? thanks

 

[plznote]

You can redo them
Just go to the Mission Archives on the Hyperion Bridge
