Guardians are weaponized versions of Watcher security drones. They are large, flying DeeBees that have both defensive and offensive capabilities. Guardians have a regenerative shield that can come back up rather quickly once deactivated. They are armed with a Tri-Shot Chaingun, a heavy weapon that can be picked up by the player if it is destroyed.
Like Sentinels, Guardians have two distinct advantages on the battlefield. Their ability to fly gives them an elevated position from which to fire their highly effective chaingun, often forcing players out of cover. Their shielding offers protection from enemy fire whilst also allowing it to fire their own weapon. However, once a Guardian's chaingun overheats, it requires a cooldown, leaving it unable to attack for a brief moment, and their shields only offer frontal protection, leaving it vulnerable to attack from the rear and sides.
