Have a read of this post that describes a sneak preview of Toy Story Mania and although at Disneyland it will be the same ride and Disney's Hollywood Studios.

Poised behind a spring-action shooter, I fired virtual ammunition at virtual targets in an immersive environment unlike any other I’ve experienced — including Disneyland’s Buzz Lightyear’s Astro Blasters, which the new ride is often compared to. Capable of firing up to six rounds per second, the spring-action shooter is nothing more than a rope with a bob tied on the end that works like a slack pinball machine plunger.

The ride starts with a practice round hosted by “Toy Story” characters Woody and Jessie before moving through five scenes that become increasingly difficult. The two-stage lightning round finale, the easiest of all the games, is where players rack up a majority of their points.
