Creating the body of the necron.

 To create the thrusters I made a box into a poly, scaled one side smaller, then in polygon mode the outer side was outlined and then extracted inwards. The lip was made with a 2d shape, then shell,then united to the box, and the top part a united modified box.

 The major middle spine was a cylinder streached. I extruded one side then move some polygons in the top. Then I selected polygons in the right and left siee and extruded again.

Finaly I moved cloned with 2 steps.

 For the hip I created a circle and attacked it with multiple boolean substrations (box,sphere and capsule were used.)Then I modified it with shell.

 Then the lower spine was made and edited with gaps and extrusions, then cloned in 4 steps and rotated, I moved and rotated to get them in shape so the first one entering the hip and the fourth one exiting have a 90 degree diference. Then to join them I used multiple hoses ,and atached them to the disks.

 I then created 4 smaller vertions of the spine that conects the hip to the torso. I used one hose for them selecting the highest and lowest spine.

 Finaly the torso was made with a champher box, I scaled in the front and back. added a small amount of the sperise modifier and then converted to poly pulling the waiste from left and right inwards and finaly selecting the center polygons I  raised moved the top front (chest) slightly outwards.

I then used Boolean to cut sections

I also added air vents again by cutting cylinders in the torso.
