Fire Unicorn is gifted if you get featured in the Community Spotlight somehow.
The latest Community Update: Flags Caps & Gowns says:
“As you’ll notice, this space is normally populated with some of our favorite creations from around the Halo-verse. Well we’ve got some cool news – we’re actually splitting off Community Spotlight to be its own blog feature! Beginning next week we’ll be showcasing more awesome community screenshots, fan art, cosplay, montages, and more, but in a bespoke fashion that gives us a better opportunity to collect and show off the cool stuff you all do. And yes, you’ll still be eligible for the 343 Fire Unicorn weapon skin by making it in. The new Community Spotlight feature is slated to take place on off-weeks from Community Updates, helping fill in those lonely alternating Thursdays with some community-curated happiness. Keep an eye out!”
That update was posted 8-2-2018 so I would imagine that we’ll soon see the new Community Spotlight Blog fairly soon. Keep your eyes pealed!
thanks
