College Buddies is a side mission in Marvel's Spider-Man. It is unlocked after completing the mission Spider-Hack, and starts in Greenwich.
Phillip Chang, an ESU student, has been missing his room-mate Carlos since the Halloween party. The only information he has is a photograph taken somewhere near the Statue of Liberty in the south end of the Financial District. He offers it to Spider-Man via a text.
Head to the south end of the Financial District, near the water. Follow the waypoint to the location. Spider-Man will notice several masked thugs beating up students. Defeat them to complete the mission.
