This is a High Poly Infantry Portal from Natural Selection. Details from the skin are brought out into the model, and more polygons are used to make certain features look smoother.
This is meant to be a Work In Progress. The UVW maps are provided for those who want to make a higher resolution texture. Please PM me (SnappyCrunch) on the NS forums if you make one, and I'll upgrade this to a full release.
The WIP thread on the NS forums is at http://www.unknownworlds.com/forums/index.php?showtopic=100533
