Defiance: Arkfall Codes (aka Ark Hunter Codes)
In Defiance on the PC, PS3, and Xbox 360, Arkfall codes (aka Ark Hunter codes) are used to earn in-game rewards. They are and have been hidden in various different places, including emails, tweets, facebook posts, videos, advertisements, trailers, websites, books, giveaways.. just about every medium currently available.
I don't take credit for any of these codes. These have been compiled from several different sources, which can be found here: arkfall codes 1, arkfall codes 2, arkfall codes 3, and arkfall codes 4.
The order that you enter these code doesn't matter.
