The third and final game in the eXceed trilogy. As always, the gameplay is tight, every character is an immensely powerful anime girl and the OST is really nice. It's also kind of a soft reboot in terms of story and gameplay, the polarity mechanic from the last game is gone, but the grazing mechanic from the first game is back. The player can also collect power ups that summon familiars for extra damage.
Just as the second game in the saga, Black Package is a remake so it doesn't have nearly as many technical problems as the first game. However, it's a bit barren when it comes to the settings menu.
Overall, I think eXceed 3rd - Jade Penetrate Black Package (what a name) is really good and so is the rest of the series. If you are gonna get it then consider buying the collection with all the games in it because it goes on sale often.
