I made these up a few years ago as a tribute to my favorite dead FPS game, Battlefield 2142. These are inspired by one of the combat walker units in the game. I took the base model and added a bunch of variants to it. I think they turned out okay.
Continuing with the GothiTech theme, here are some cars in that same vein. The problem is that I'm really not a very creative person, so... yeah. Cars.
