There are three classes in all. Vanguard, Archangel and Sentinel.- Vanguard (The use of dexterity and cunning to retrieve the most rarest of technological finds).
- Archangel (Strong leadership to fortify and enhance your comrades on and off the battlefield).
- Sentinel (Unrivalled staying power, specialising in archaic power-armour to take any threat).
