Here's a fan-made Facehugger model I finished after watching Alien: Romulus.
This one is mostly based on the Giger design from the 1979 movie, with some custom artistic touches.
It's game-ready, rigged and fully animated (with locomotion animations as well)!
Sculpted in ZBrush
Retopology done in Maya
Textured in Substance Painter
Rigged, animated and rendered in Blender
