This Mech was built using Blender. I have actually taken the project all the way up to rigging and some animation. It still needs to be textured! I built this one as a personal project in my spare time.
The goal was to model a very high-poly Mech so that close-up and high detail views would be mostly contained in the model (as opposed to in the textures). I was very happy with the results! I will update the model with textures sometime in the near future, I'm sure.
