Inti Creates have confirmed that Azure Striker Gunvolt will no longer include an English voice track.
The studio answered a fan question on Twitter in that "the game (doesn't) have English voice, for the specification has changed." A second Tweet noted how Japanese voice acting will be "implemented in the North American version," but only for the battle aspect it seems.
Whether the game will have some English voice-acting remains to be seen, as the sudden change in language could be quite jarring for players.
Finally, the studio also confirmed that there currently aren't any plans for DLC.
Does the lack of an English-speaking voice-over put you off the game?
