HFW hit the mark as expected, though I think the Forbidden West is a lousy lazy name.
Horizon Zero Dawn
Horizon Zero Dawn : The Frozen Wilds
to
Horizon Forbidden West ?
Hmmm, how about,
Horizon : The Forbidden West
or
Horizon : Forbidden Wild West
or
Horizon : The Forbidden Wild West
or
Horizon : Forbidden Western Wilds
or
Horizon : The Forbidden Western Wilds
I dunno. Don't like the name as is, but liked everything else I saw about it.
