Those of you that tuned into BlizzCon will already know that today is when the Nexus Challenge in Heroes of the Storm kicks off, but for those of you who aren't aware, from today until January 4 you can compete in Heroes of the Storm for a number of prizes.
You can get five heroes free when you play 30 Heroes of the Storm games with a friend before the closing date, and as a bonus this also includes the amazing Oni Genji skin in Overwatch, which is pictured below and unlocks after you've played the first 15 games.
The challenge can be played with one or more friends and the matches can be played co-op vs. AI, unranked draft, ranked modes or quick match. If you're playing on console, though, be sure to link your PSN and Xbox Live accounts to your Battle.net account (instructions on doing this can be found here).
The rewards for playing 15 games are numerous enough, including the Oni Genji skin, portrait and spray for Overwatch, as well as Zarya and the Genji portrait in Heroes of the Storm. 30 matches unlocks you a lot more for Heroes of the Storm, though, including Auriel, Greymane, Kerrigan, Li-Ming, Orochi Hovercycle Mount, and a 30 Day Stimpack.
Which of these rewards is the best? (We won't think less of you if you say anything other than the Oni Genji skin).
