Prime Servitor is the final boss in the Area 51 Alert
Strategy Easy/ HardEdit
Keep an eye on the Health Barrels laid out around the room. Use them sparingly because they are on a SLOW respawn time.
The Best way to defeat Prime is to have 1 tank 1 healer 1 Controller and 1 DPS. the Servitor will be easy than. Just lay down the damage until Servitor flies up than he will either summon adds in which everyone will just need to kill them. Or he will shoot rockets, this is where your team will need to dodge roll until it is clear. Than repeat until killed.
