To ensure the method of using Idgel doesn't fall into the hands of the Beritra Army, Alkatron asked you to find the Command Unit of the Special Research Troop and destroy them all. After you killed Staff Officer Suyaroka, Chief Medic Tagnus and Blade Terror Ukahim from the Command Unit of the Special Research Troop as instructed by Alkatron, you reported to Liponia and received a reward.
