Halo's Master Chief is in Destiny, sort of. Eagle-eyed Reddit user SmokingGhost happened upon the Chief on Mars during a strike, though not in the way you might expect. Turns out, the developers created a building that resemble's Master Chief's helmet, right down to the orange-ish visor. Judge for yourselt, but in our humble collective opinion, the similarity is too spot on to be an accicent.
According to SmokingGhost, he located Master Chief during a Strike mission while battling a Goliath Tank.
It is the back side of the building that the first and second lieutenants are in or go to. You can see it also when going toward the third one in the tank if you turn around and look up to it like I did.
What do you think? Is it a Halo Master Chief Easter egg, hoax or just a funny coincidence?
