Trigger is a great game. You have to beat the time and also make sure to pass every checkpoint. If you complete these two conditions than you can go on to the next level. The graphics are pretty good but the car handling takes a while to master. The game is fun especially when you are going over bumps and your car takes of the ground. It is easy to lose control of the rally car when you are going at top speeds. The game is free and works well on Ubuntu Linux. If you want to download it just click on Applications and Add/Remove software. There doesn't seem to be any development on the game currently and the only links I found are below. Nevertheless it is definitely a decent rally car game worth a download. If you know of a official website for this game let us know.
