The core element of the game, designed by Olda Rejl, Ondra Cigánek and Ivan Dostál, is a fresh and rewarding system of three gears which determine what actions you can or must perform in each round. Crash Derby is being developed in collaboration with Prusa Research and it's a title explicitly designed with the intention of allowing the community to create new content for it, like additional cart models, obstacles or entirely new gameplay elements. At launch, a range of expansion elements will already be available to print at home on the Printables website, with more to come. That way, soon there won't be a two copies of Crash Derby that would be the same. Crash Derby is designed for 2 to 4 players aged 8 and up, and one game will take approximately 45 minutes to play.
