Garrus Vakarian is a Turian, a former investigator of the Citadel Security Service, a loyal colleague and one of Shepard's best friends, who was on the captain's team throughout the events of all three parts of the Mass Effect trilogy. After a skirmish with the mercenaries of the "Blue Luminaries" at Omega Station, the right half of Garrus' face is disfigured by scars left after being hit by a rocket fired by a flyer.
The skin is made qualitatively and works in SAMP without any problems.
Have a nice game!
