Pirates are adversaries that Commander Shepard encounters while exploring the galaxy in 2183. They are equipped with shotguns and/or assault rifles and are often accompanied by dedicated snipers. They are usually human, krogan, and turian, but it is possible to encounter asari and salarians amongst their ranks.
Pirates have between one and three bars of shielding; as is the case with all Mass Effect enemies, it will regenerate over time. Their health also regenerates and they can use Immunity to reduce damage taken. On higher difficulties, they will also use Shield Boost. They will take cover quite often and flank you if given the chance to do so.
Pirates will usually start off with assault rifles, but switch to shotguns at close range. Using Sabotage will simply force them to switch to their other weapon, rather than leaving them completely defenceless like Geth Troopers. Some pirates can also launch Carnage from their shotguns.
Krogan pirates will have more health than other species, and can charge you at close range for melee damage. They will also be able to get back up the first time they’re killed. Equip Chemical, Incendiary and High Explosive Rounds or kill them in the air (possible by using Lift, Throw or Singularity) to prevent this revival and use Throw and Neural Shock to counter their charge.
