The A.R.C. Science Team are first seen being held as hostages by Marcus. If Jake does not surrender, they will be ruthlessly killed.
If Jake does comply, they are saved and when Jake fights back, they all promptly flee to a generator room for safety. After Marcus is killed, Jake can meet them and they express their gratitude.
One of them mentions that while Marcus was a "sadistic bastard", he was right about one thing, stopping the infection.
The science team then find a place where they can monitor the security system in their area and allow them to restrict access from hostiles.
If saved, their fates are left unknown.
