Marauder

Marauders are synthetic-organic creatures derived from turians and mutated by the Reapers. They first appear in Mass Effect 3.

Capabilities
Offensive

Marauders are armed with Phaeston assault rifles, which they use both at range and in melee. They can execute downed players in multiplayer by stomping on them.

Defensive

Marauders possess a layer of shields that make them more durable in battle. They also have the ability to coat Husks and Cannibals in scab-like armor plating and can dodge attacks by rolling.

Tactics

 * It is advisable to keep constant pressure on Marauders during a fight. Marauders that are not busy firing or taking cover will fortify allies at an alarming rate.
 * Marauders can give armored plating to Husks and Cannibals. This process takes several seconds and has a distinctive sound and look. Any damage to either the Marauder or the recipient will interrupt it.
 * It is a priority to deal with Marauders first unless there are other deadlier foes on-site, such as Brutes or Banshees. This is due to a Marauder's ability to provide armor plating to other husk units.
 * On Normal difficulty, it is possible to make a one-hit kill with the sniper rifle by performing a head-shot paired with Adrenaline Rush and a suitable ammo type.
 * With multiple weapon upgrades (and in certain circumstances or harder difficulties, armour) or rail amps, Infiltrators, or turian or human Soldiers can be lethal. An Infiltrator can use Tactical Cloak to kill off Marauders in just one shot (although not on Gold) with one of the high-power sniper rifles. A Turian Soldier can use Marksman to increase headshot damage by 25% through the Rank 5 "Headshots" evolution, or a Human Soldier can use Adrenaline Rush to increase damage by 45-65% damage. Both options can achieve the same results.
 * Marauders have moderate shielding that can be eliminated through a single use of Overload or Energy Drain. Follow up with a powerful weapon such as the Widow or Mantis to kill them with a single headshot. This works on any difficulty.
 * Marauders are less likely to dodge attacks if they are staggered by gunfire, in close proximity to the player, or focused on another target.
