Last year I redid the Pain Pills and Pipebomb in Left 4 Dead 2. After many requests, here is the Adrenaline remake. It can be doanloaded for Left 4 Dead 2 here: http://steamcommunity.com/sharedfiles/filedetails/?id=1185687047
My remade version has 4108 triangles, original game asset has 4668 triangles. Portfolio textures on final asset are 4098^2, vs 1024^2 used in final game release. Original game asset uses 512^2 textures.
I started this model a year ago, but I felt I needed needed to become a bit more familiar with the 3ds Max/zBrush boolean/dynamesh workflow explained by Ben Bolton in the Polycount forums.
