Limited stealth promo to commemorate the deadline for pre-registration of the game. Or something. I dunno, the marketing for this game has a budget of 0 dollars and is basically just the producer tweeting stuff like this every few days. Lol.
It's a mobile title, but they've shown off like 4 seconds of battle footage and it looks like Valkyrie Profile 1 battles with Valkyrie Profile 2 graphics.
