Carrera SO-O has several game modes: Championship, Single, Time Trial, and multiplayer (online with up to 4 players or 2 players from the same PC).
The game is equipped with very basic, although well developed, graphics for being a free game. There are 9 tracks and up to 10 mini cars to choose from in the game, each with unique characteristics.
With a bi-dimensional aerial view, you can control your car and compete to be the best in the race. Also, the game incorporates some pretty nice special effects and background music.
