Isn't this a crossover fighting game?
No. Its a new-ish Fighting Game Franchise.
But it has guest characters like DoA.
Rimi Sakihata, Kurisu Makise from Chaos;Head and Steins;Gate respectivly.
However, the first game was never localized and we merely got the spin-off PB: Battlegrounds
Well it certainly looks pretty.
I absolutely loved playing Battlegrounds (even if it didnt get a English dubbing) so i look forward to get game coming out.
