Test Subject

Test Subjects are people who have been horibly mutated by experiments peformed on them by the salarian Dr. Saleon.

Dr. Saleon was a doctor on the Citadel who was secretly growing organs on the people, then if viable, removing them and proceeding to sell the good organs on the black market. Garrus Vakarian was assigned to the case, and after getting a hold of a few of Saleon's workers, one became sick during the interview. Garrus ordered a full body scan and the whole truth came out. Garrus tracked Saleon to a leaving freighter, and Saleon had kidnapped the crew. He then ordered Cidadel Defense to shoot the freighter down, but C-Sec countermanded his order. Garrus then lost track of the doctor, but eventually found him again, Saleon changed his name to Dr. Heart and was still conducting experiements.

Tactics
Test Subjects are simiar to Thorian Creepers in both their attacks and their method of fighting. They will charge at their enemies and try to spray them with their toxic spit, causing damage that bypasses shields. They will alos use melee attacks if they don't use their spit, but they are easy to knock down with enough weapon fire or biotic powers.
