Rise of Nightmares

*STORY-RELATED, SO SPOILERS AHEAD!*

Act 8 is the last act in the game, and is very short and linear. No enemies at all apart from the boss, which isn't too hard if you know what to do. Whenever a QTE (quick time event) pops up, just do as it says to dodge the tentacles, and when you're free to move, use your Azoth glove to shoot energy balls (don't charge them, just shoot) at as many of the tentacles as you can before they go away. Repeat and the boss will eventually fly around for a bit, shooting balls of goo at you, which are all dodged through QTEs. After she comes back down, you'll have to go through the part with the tentacles again, and sometimes the boss will shoot some balls at you as well. Everything can still be dodged through QTEs, except for a barrage of balls the boss seems to use quite randomly. For that you'll have to just block. When all the tentacles are gone, run up to where the face is on the boss, and get very close to it. Hold out your hands straight in front of you, close together, and quickly move them out to the sides, as if you're pulling open the pod thing. When the face is exposed, shoot it once with Azoth. Repeat the tentacles + face part two more times and the boss is dead. After that, the last part of the act pretty much plays itself.
