I played this game when it was in arcade on Naomi 25 years ago. I spent so much money in this arcade game because, it was sooooooooo cool to play a helicopter.
13 years later, I bought a japanese DreamCast for playing at home Zero Gunner 2, it was so cool to replay this game. But my DreamCast JP is so fragile, that I can't play a long time with it.
And........... the bad news is here, I found Zero Gunner 2- on Steam, the game is so buggy, it's unplayable. Don't buy the Steam Version, the editor never fixed the game..
So yeah, I really want this game on GoG.
