I had several Mechs in the store, which you can still see around the site in various photos. And when the site launched, I was advertising them. So, where did they go?
Long story short, there was a ton of interest in them but some felt they were too similar to the original MWO designs. None of my models are ripped meshes from that game, I built them from the ground up taking screenshots and the concept art as reference, as well as changing parts where I felt appropriate.
However, as they ended very similar and I want PMW to be a reputable business, I decided to remove them. Contact me via email if you want additional details.
