Zero Gear is a physics-fueled, multiplayer kart combat game. Deck out your kart and character before jumping into one of many different game types. Awesome kinetic items help to spice up the action. With an open scripting system for creating new game modes, as well as support for user-created maps, karts, characters and more, you could experience something new every time you play. The potential for tiny vehicular mayhem has never been so humongous! Boost, flip, spin, tumble and slide your way to victory! (currently in beta on the PC platform)
A new version of Zero Gear is live on Steam! Along with some bug fixes, we also have a new map, “Aqua Race” included. Check it out!
