Toybox Turbos 

Toybox Turbos is a top-down racing game with miniaturised cars. Within the game you will get to collect and customize 35 vehicles and take on 18 obstacle and short-cut filled circuits built for chaotic, combative competition. Your goal is to stay on track by using a range of awesome and ridiculous power-ups to send your rivals into a spin, including mines, machine guns and, of course, giant car-mounted hammers.
