I assume they are trying to appeal to Fortnite fans. Which, is actually understandable. Definitely easier to sell skins when people can see their own skins. And it's kind of refreshing to see them try to expand their audience in a common sense, give them what they like kind of way.
The old guy in me, who played the original Halo, definitely did a double take at this headline. But I think it's worth a shot. Makes sense and could be cool.
