This is the most difficult mission in the game with Nero, and consists almost entirely of a boss rush.
Machina Ex DeusEdit
Here you will start this mission. Just move to the next location.
Stairway to HeavenEdit
At this point you play a very familiar and annoying game. It is the Dice Game from Mission 6 but here are some significant differences. First, the game is divided into five circled game fields. Second, it will go over and over the circle until you hit the yellow or purple square. Third, the last difference and the most frustrating one is that at the end of each field you will fight a boss. Still, other rules are the same: red square - fight, blue square - Red and Green Orbs, white - nothing. Also you may use cheating method as before - if you Buster dice right when N number is up, N number will fall. Use it to survive, as constant fights with small supply of green orbs could be really annoying, especially on hard modes.
You will have boss fights in a strict order: first Arma, then Ignis, Nix, Draco, and, finally, Vermis.
It isn't a boss fight, though it can make you nervous for a moment. Here you will meet with four Bianco Angelos and one Alto Angelo. You may try to fight them as usual, or may try to play cheap. If you want to end this quickly and without much effort, wait until knights start to charge their energy ball attack, and use Charge Shot (even Level 1 will be enough) or even Devil Trigger just as it starts flying. This will deflect it back, instantly killing most or all of the Angelos and netting the player an SSS style rank.
