In Mass Effect 2, the Illusive Man will email the player once the Collector Armor is ready for use. Unlike most other armor sets, the Collector Armor is purely defensive in nature, offering no additional offensive capabilities. The armor itself resembles chitin, giving it a durable quality. The Collector Armor imparts a variety of bonuses, mostly built around speed and vitality. Just because Commander Shepard has to fight the Collectors in Mass Effect 2 doesn't mean he's barred from wearing their armor.
