I've been working on the weapons over the last few days. They are still very rough/early/basic but I wanted to at least let you choose a weapon from the character UI and have it actually equip (showing up with graphics) and work on the car. Right now it's just basic yellow bullets but I'll be adding rockets and some kind of shotgun-like blast next.
I also added some names/portraits that appear over player's cars. I'm still experimenting with position and whatever (and all the UI graphics are still filler/temp). I'm going to be adding healthbars to AI racers and players soon too.
