An old scene that I revived and finally finished. The starting point was the remarkably grotesque Specimen 23 model by Sixus. Originally, the alien was posed as a peaceful -- but ugly -- creature with a marine escort. At some point during the endless scene-tweaking, however, things broke down, and it acquired armor and, eventually, guns. Things went downhill from there.
The alien and its armor were re-textured using Carrara shaders. Everything else is used largely 'as-is'.
