These are some armored vehicle concepts. They were built for a car combat mobile game prototype. There were multiple levels of armor that you could gain as you progressed through the game. These are the fully-loaded versions. I was tasked to take some existing cars we had in our library and design, model, and texture up the armor and weapons.
One of the vehicles was based on this artists model, which can be found here:
