While the game may seem like a total rehash of RBS, there are
many additions exclusive to this game.
For one, full screen animations done from scratch are displayed
in the opening and within demos, the game has an original story, and there
is a new character "Alfred".
Alfred is a projectile-less character which has special moves
that leaps him forward or shoot out a short-range wave in front of him,
making him resemble a fighting pattern mix of RB2's Xiangfei and Rick.
In other details, the character select screen is totally new
and the line system has been dropped- the game is a totally flat
plane system now.
