Some words about the model:
The model contains 11-12.000 polygons and doesnt use "regular" textures (except one), only solid colors with some phong-effect. I made 2 LOD models, like in the case of stormtrooper model. The model doesn't use any stolen parts, but uses the original Police-animations. If you use this model I recommend to turn off the HDR. The model replaces the original Police model.
Extract the zip file into your "STEAM\steamapps\<...>\half-life 2\hl2\" folder or your mod's folder.
I hope you'll like this model, because it was really hard to make this one. (much harder than the stormtrooper)
SMALL UPDATE: Now you can download version 1.1 (some little fix)
I made a modified version for Barney, I hope I can upload it soon. (there is only 1 problem what I have to fix)
