“Use the Arc energy to disrupt the protective barriers barring the way to the time bridge.”
Head out the Campus-9 area, down the slope and into the next portion. Once again you need to find the Arc Charge. This time, the Arc Charge can appear in a number of locations. A Nightstalker Hunter with Keen Scout active will immediately know where to find the Arc Charge. They can either head for it or relay the location to another member of the Fireteam.
The charge can appear in any number of locations. Whoever retrieves it will need help to make it to the next Time Barrier.
