Geth Destroyer

Mass Effect
The Geth Destroyer is a fearsome and deadly enemy, standing eleven feet above the ground. Their armor is dark grey with a yellow stripe down the middle of the chest and greyish details, and a bright blue 'flashlight' eye. The Destroyer carries a pulse rifle (which also apparently has a shotgun function because they can use Carnage), has four to five levels of shielding and is extremely resilient. One or two Destroyers are usually found amongst groups of Geth Troopers.

Tactics
When attacking, the Destroyer will slowly advance as it fires, occasionally hit you with Carnage, then charge and close for a powerful melee attack. Keep it at a distance with Sledgehammer Rounds in an assault rifle, or Throw. When the Destroyer charges, Lift will send it flying overhead and disable it for a few seconds when it lands; it can also launch it over an edge. If it is available, Destroyers make excellent targets for AI Hacking.

Mass Effect 2
In Mass Effect 2, Destroyers are rarely encountered, but are even more dangerous at close range as they are armed with flamethrowers. Unlike the Blood Pack and Blue Suns Pyros, they cannot be made to explode by shooting the fuel tanks as these are not visible. It is, however, possible to detonate an unshielded Destroyer with powers such as Incinerate.
