Okay for Horizon Z, this is a story of 4 characters (stella, juna, titus, and axel) with different pasts (each character has a long past so if someone wants to hear them then ill post them) okay so the story is this:
Each member has had connections with vension croix, the leader of the infinite, an organization of assassins. the main character, stella, was told to assassinate jason xavier, a man whos job was to stop an experiment of the infinite, not telling stella what the experiment was about… (further on) stella and the rest find jason xavier, they attack, then as he slowly dies, he told them the real intentions of venson…to create an evil corrupted stella (the boss at the end of the game), and to open a curse rift that can reverse the life of people, turning them into blood thirsty zombies, now they must stop venson, and takedown stellas doppelganger, will they succeed? or will venson get away with his sinister plot.
boss stages of dark stella:
1: dark stella
2: rage dark stella
3: eye of evil
In order to reveal the ending, you must beat the game…
