So here's White Rock Shooter in BR*S The Game

 Also a sexy logo!

Famitsu revealed a couple of new characters for the upcoming PSP game a couple of days ago, both on the website and their magazine.

 White Rock Shooter!

 The first is not officially named as of yet, but she appears to be the character that the “White Rock Shooter” figma (which will be distributed with the Limited Edition of the game) will be based on.
While nothing else is revealed save for the design, I suspect she’ll be an antagonist, if gaming tropes hold true. Just look at her, for heaven’s sake. White with magenta eyes? Sipping tea ojou-sama style in a chaos-themed environment?

 There’s also Grey, and she’s apparently B★RS’ prototype. She doesn’t seem to have any ranged weaponry, though, but she’s clearly set out to be the protagonist’s main ally, with *cough* yuri undertones in one of the magazine’s screenshots.

 Here’s a shot of the game’s status screen. Note “Blade” being one the 3 damage types you can deal, possibly indicating that you can use melee attacks in battle. I was wondering what the blade on the end of her Psycho Cannon was for.
It’s also apparent that you’ll be taking on the aliens solo, so allies like Grey won’t join and fight alongside you in a party. =(

 B★RS has a couple of vehicles at her disposal, the first being the Blacktrike, and the second being the Brunhild. How exactly they’ll be used during gameplay has yet to be said, but they’ll definitely appear in at least more than one cutscene.

Well, I’m totally sold at this point, and I can only imagine the reveals will get better as time passes. Stay tuned for more updates.
