Atlas "Monolith" helmet displays a monolithic headpiece that fuses into the torso through a taller and heavier neck guard while the skin proposes denser details with metallic accents and an increased emissives presence.

The helmet is split in 3 parts for easier rigging and to avoid extreme deformations (see rigging test video - pls note that's just a quick test for reference to show approximately how the parts should interact, nothing perfect or final.)
