The name of it is down to my obsession with giving things far too complicated names. A Valkyrie is a female figure who decides who dies in a battle, and 'Decaying' refers to her getting more and more damaged as the game progresses.

It's something I've done for a while, even with stuff like multiplayer maps. I just don't like giving stuff generic names like Desert. It's gotta be Dune, or something. See also: Call of Duty: The Sentinel's Ascent.

As for Nighthunt, it's actually a three-game trilogy which begins with Black Widow, if the confused you. The Sentinel's Ascent and the third game (whose name is, again, hidden on the wiki somewhere) are the other two games.
