Part of the story, unmissable.
The boss has 3600hp.
With 2 main attacks:
- Lasers with Blue Kinect Explosions (blue AOE when exploded). Easily avoided hiding behind the walls, but if you get stuck between them, you will be in big trouble (right side is better, left side is where you mostly get stucked)
- The Tail attack (the one that comes from the roof). Just keep moving around, and you shall be fine.
**After certain amount of damage, the Spine will spit out "CELL", totally easy to handle (4 times).
The Trophy will pop out, after you go into the cave (opened after you defeating The Spine), and finish up The Spine.
