Firstly, I am assuming that the Enigma answer can be found from clues located only on the warframe skin/helm itsself, and not from the text or background of the photos themselves. Please correct me if i am wrong.

Secondly, so far i have not found any outstanding clues on the skin, but i will keep looking. I will post here with any ideas i come up with for possible solutions. Tell me if any of them are correct please.

Lastly, I love the skin, and will definately be getting it when it becomes available. Great Work!
