At least according to Game Nyarth, Aquaplus will gonna show “a new 2D fighting game” (???AF?09???2D???) in the next moments on his Aqua Festa 09 event.
Aquaplus is known for Eroge games… so i dont know what to expect about this, except of course more ANIMU DONJON GAMES!!11
Game Nyarth is an awesome source for those things so lets wait…
EDIT: Game Nyarth THINKS (just rumours) that this new title is the NEW French Bread (Melty Blood) game!!
Just because is Aquaplus… so who knows.
