Sea Spider Boss Fight Tips
If it lunges in IN THE AIR at you, dodge forward and under it when its coming down.
If it lunges at you ON THE GROUND, dodge forward left or forward right to avoid it.
If its gun is pointed toward you it will either do a dual blast you have to dodge twice, or a vertical slash you dodge once.
If its gun is pointed to the side and charging it will do a horizontal slash you need to boost up to avoid
The tetra legs are the best here, because you can stay airborn and avoid his little top like spinning slashes, and the giant lazer blast he does at the ground can’t target you.
I did tetra legs, 2 plasma rifles, 2 cruise missile shoulders.
Hope this helps!
