This trophy is story related and cannot be missed. This boss fight occurs during the mission "Errand Boy." The Specialist is pretty easy to beat, especially if you have purchased the Whipfist offensive ability. Lock on and keep your distance from him. Start charging a jump and wait for him to stop holding up his electric wand and point the laser site on his gun at you. At this point, quickly jump to one side and use the and use the Whipfist's special attack (press TRIANGLE) in midair to damage him. At one point he will summon some infected to attack you, and then later he will summon some military personnel to attack you as well. Consume them for health if you need it, but otherwise you should keep focusing on attacking him. Just keep dodging and attacking and he should fall with little trouble.
