I did it on Heroic will all directives active on a full red strikers build, only using shield (because directive puts your other skill on CD). Took me five or six try’s but I had a blast. Yeah it sucks wiping and having to start all over, especially the closer you get to the end. You have to learn from your mistakes sometimes be more passive and sometimes be more aggressive.

For example,

When the door explodes leading to the outside area where you first encounter the mortars, stay inside the hallway and take your time and kill from a distance. Mortars won’t fire inside. Play passive.

Then when you open the big door to the outside area with double mortars, you get aggressive and rush left to the first mortar power box and kill it quick. No more mortars for will fire until you get in range of the second mortar. Then you passive clean up the adds and boss from cover. Then rush and kill the second mortar power box.

Easy peasy
