Locate and scan 3 dead Exos on Europa.
"Lookin' like some of those flashes are of me trudging through ice and snow, passin' bodies of my fellow Exos. One of 'em looked to be surrounded by Vex technology, another amongst the ruins of an old city, and another surrounded by factory equipment. The rest are a blur… Shame I left 'em behind. Wish I knew why. Bet you might figure that out." —Banshee-44
