As the title suggests, this is the sequel to Psikyo's lighthearted bullet hell shooter "Gunbird" which features a cast of mostly new characters (the main hero, Marion, is the only holdover), a new storyline (trying to find a magic cure-all potion and keeping it away from the clumsy pirate trio) and more.
Like the original, this is a virtually arcade-perfect port of the game, with the only changes being a remixed soundtrack (the original is missing though) and the addition of a "2P Story Mode" that allows a single player to play with two characters alternating when lives are lost, which also mixes up the story cutscenes and offers more replay value. This one also includes the Score Attack mode with online leaderboards and multiple difficulty levels. The only tweak that needs to be made is the addition of an "Exit" option on the main menu, currently you have to press ALT+F4 on the keyboard to exit (a few other of these games have the same issue).
Unless you wish the original soundtrack was present, there's really nothing to complain about here-City Connection has done another great job of porting Psikyo arcade titles to Steam and there are more to come. This is another one that is worth buying, and can also be enjoyed without having to play the original first. Also this is MUCH better than the subpar mobile version. Buy this and help the developer/publisher keep the Psikyo games coming!

GUNBIRD 2 is a pretty acceptable sequel for my taste and in my opinion!

Slight improvements, new characters on some platforms at the time and of course... The soundtrack is exceptional!

If you're a Tohou fan and liked GUNBIRD 1... It's impossible for you not to like 2

The only thing I suggest is that you buy the game when it's on sale, because it's a bit expensive!

GUNBIRD 2 + Absolute fun = MAGIC ✨
