SEGA has announced that Super Monkey Ball: Banana Blitz will see the introduction of two new characters - YanYan and Doctor.
YanYan's a "young, vivacious female monkey" apparently, while Doctor is "an older monkey with a past steeped in mystery due to his acute case of amnesia".
There's more to them than that though - as each will have particular strengths and weaknesses in acceleration, speed and jumping ability.
SEGA says the size of the monkey ball and its weight will also play a role in a character's performance in Banana Blitz, which introduces jumping - activated by flicking the remote or pressing a button - to the series for the first time.
The full game will also feature a huge number of mini-games, and is due out alongside the Nintendo Wii in Japan on December 2nd. For more, check out our E3 impressions.
