Cave, creator of the bullet-heavy arcade shoot-'em-ups that you love, is currently developing a "new, original shooting game" for Japanese Windows Phone 7.5 devices, according to a press release recently issued by Microsoft.

Cave has previously dabbled in porting its shooters to iOS devices (Deathsmiles being the most recent), but this marks the developer's first original offering for Windows phones. Unfortunately, no further details have been revealed regarding the upcoming title, nor has a release date been issued.
