Ahead of the game's Japanese launch next week, SEGA has attached a Fall 2018 release window to Valkyria Chronicles 4 here in the West. Previously, a vague '2018' was all that we had to go on.
What's more, the title's official English site is now open. It's got details on the story and characters and all that stuff.
We imagine that we'll be getting a confirmed date within the next few months, but until then, hop in a tank and roll into the comments section below.
