When I first saw this title, my gut wanted this to be a Z.O.E-ish high-speed aerial mecha-game, where mechs orbital drop from space onto a hell-on-earth, over-taken by aliens, and dive deep into alien hives that dig deep into the core of Earth.
... that just sounds like the MuvLuv game I'll never get.
Still, what's the possibility that this is a 3rd-party SCEA-published game that we haven't heard a zilch about? Not every SCE-published works-in-progress gets leaked out.
