Canon Fodder: Annual Achievements
Finally for you unhappy people about UNSC air vehicles not being in multiplayer, a question was addressed about UNSC Air vehicles. It will return to the multiplayer. Please see the link above. Your questions and desires all answered with one word. However it does not say which multiplayer it will return to. Hopefully they can rephrase the question to, will we see it in Halo 5 multiplayer.
This is something that was confirmed a while ago but nice to see it come back to the surface. 
Yeah,I would love to be able to fly with passenger gunners in a hornet.
I hope they’ll add it in a REQ update, and add it to Forge.
Let’s hope it’s the falcon!
