"Moero! Nekketsu Rhythm Tamashii Osu! Tatakae! Ouendan 2" is the name, and apparently that first part translates to something like "Burn! Hot Blooded Rhythm Soul!" We sort of hoped it would.
The Dengeki listing is too brief to give us a steer on what the Ouendan chaps - who typically rescue people from sticky situations via the medium of dance, are getting up to this time - but there is "1-4 player" note, which is good news.
No idea what we're talking about? "Osu! Tatakae! Ouendan" is a marvellous DS rhythm response game, which arrived in Japan quite some time ago, and won broader appreciation when the concept was adapted for Elite Beat Agents in the US. The Japanese and US versions are quite distinct from one another, and both are well worth owning. Goooooo!
