The initial impact of the torpedo has a small area of effect ('AoE'). The DoT effect is stronger than that of an equivalent-level Plasma torpedo. Upon impacting the enemy's shielding or hull, they also apply a radiation damage over time ('DoT') that bypasses shields. Hargh'peng projectiles move as fast as Quantum projectiles, while causing slightly more damage at the higher levels (3313 for a MK XII Quantum torpedo, vs 3377 for a MK XI Hargh'peng torpedo). The Hargh'peng Torpedo Launcher is a ship weapon that can be acquired from the “The Doomsday Device” mission, the “Tradecraft” mission, a duty officer assignment “Obtain Experimental Harghpeng Torpedo Launcher”, or as a random drop.
