...that doesn't give anything new.
The storyline is filled with anime cartoons. The story moves along and some bits can be funny hense the script isn't too professional.
Depending on whether you play one or two player the story changes. But the gameplay itself is bland and nothing new.
This is no Radiant Silvergun. It's no Raiden. It's just another shooter where you have to dodge massive bullets and bomb right before you die and collect powerups.
The weapons also fail to interest nor are they unique. Only each character's bombs are very weird and amusing, but they scream these taunts that get incredibly annoying after a while.
If you're an expert shooter, skip this one. Wait for Ikaruga. Otherwise this might entertain, but not for long.
