Been trying to get this done for a triumph but seems near impossible. The vents you shoot to trigger heroic do NOT stay open long enough and they take what feels like clip of machine gun ammo to break, its so silly. The damage you take from inside the dome as well is far to high you can't stay in it longer then a few seconds. As a solo player its very fustrating. On EDZ its easy but on Neomuna its like buffed to impossible, it needs to be changed
