Fans of vertical shooters, and CAVE's previous iPhone and iPad offerings should be delighted to watch this trailer for the upcoming Bug Princess 2: Black Label.

Aside from being full of bullets, bullets, and even more bullets, it looks like there's plenty of features that fans of these games should love (the ability to slow down time to recreate the arcade lag effects was a highlight personally). The greatest addition being a boss rush mode, featuring the bosses from this game, and the previous Bug Princess as well, where the player is graded on their performance and ranked online.

The app store can always use more high quality action games, so i'm definitely looking forward to giving this a whirl. The release date is still 'to be determined', but you can bet that there will be an Appspy review out as soon as possible when it finally hits.
