The Wild West is really filled by bandits, shooting and you as the sheriff must put everything in order.
The game is split into two phases. The first takes you riding a horse and shooting enemies so you reach a certain city. Collect different weapons, health. The jumps over obstacles are automatic so you can concentrate on the shooting. When you reach the destination the big shootout happens. Shoot the enemy as fast as possible and get the bandits out of the city.
