We recently took a couple of weeks off so we could take part in a Game Jam. Big Air Desert Rally was the result of 2 weeks of fun building a simple Hill Climb style racing game.
The game was made by two people, one coder and one artist and everything, apart from 2 car models which came from our main game project, was made for the Jam. We used Enviro 3 as the only other asset in the game after that more than 150 scripts were custom written for the game.
The physics used is standard Unity Wheel colliders with a little bit of extra scripting on top.
Work will continue of the game and if you like it a wishlist on steam would be a great help for us Big Air Desert Rally on Steam
