Achievements completed 100% yesterday.
Some are abit tough need to try few times, especially those limited time ones.

Limited time ones are those in the 'Mastery' category.
Kinetic blast, and in fact all those under the 'Kerrigan' category, do each of them in the same mission although not mentioned. =|

For Kerrigan Power 70, load up a previous campaign save. Need to be the archives from the leviathan one, not the master archives outside.
If you find that your achievement's kerrigan level didn't progress up even if your Kerrigan did in fact level up, then load a save even prior to that. And redo some of the missions, it's pretty fast anyway on normal mode.

no need to restart the campaign all over again.
if you load the last mission and level up still cannot, then load a mission save prior to that.
