Trigger is a free 3D rally car racing game. Fun for all the
family. Trigger comes with a number of challenges where you have
to race several tracks to finish each challenge. When racing a
track, you have to reach several locations marked by pulsating
rings in sequence. You win a race if you reach the last location in
time. Trigger is highly customisable, and it's easy to add new levels
and vehicles.
