Locate the Giant Exo hidden in the Exo facility.
"Those Dead Exos you found are giving me a headache something fierce—and even more flashes. That blade again, in more glory than before. Must be important. Also saw frozen-over labs filled with dormant Exos. Even saw one the size of a giant. Gonna take a guess and say that's your next stop… wherever it is." —Banshee-44
