히어로즈 오브 더 스톰
During the "Nexus Challenge" event (November 15, 2016 – January 4, 2017), each player who completed 15 games of "Heroes of the Storm" together with a friend received the Oni Genji skin, Oni Genji Portrait and Oni Genji Spray in "Overwatch", and Zarya as a free hero in "Heroes of the Storm". After completing 30 games with a friend, players unlocked four additional heroes (Auriel, Greymane, Kerrigan, and Li-Ming), the Orochi Hovercycle mount, and a 30-Day stimpack in "Heroes of the Storm".
