The BF5 work with their old Kharamanos ally, Tromp, to deliver a debilitating blow to Kalus and his Vandals. They plan to covertly penetrate a caldera in the middle of the Vandal homeworld that is the main power core of the planet and plant a Phase Nullification Bomb. When detonated, it will destroy any Sentient-based technology on the planet – effectively taking out all the Vandals' vehicles and weaponry.
