Escape from Camp Run-For-Your-Life

Plot
The reader attends a summer sports camp that turns out to be run by alien invaders. There is also a mountain known as "Zombie Mountain" nearby, which is aptly named. One interesting choice-making method employed in the book is the requirement to point at a location on a map of the United States. There are more than twenty possible endings. Oddly, there are no tests based on the real Goosebumps series, despite the fact that there were tons of camp based stories.

Story A involves you being forced to team up with a girl you really do not like (Kim) and having to deal with escaping the zombies

Story B involves you joining the only other character who has free will after you pretend to eat the eggs given to you.

Bad Endings

 * Many involve Kim simply ditching you, leaving you to die.
 * You switch roles with a skeleton after taking its skull (It turns into a human and you become a living skeleton).
 * Eaten by an alligator (2 endings).
 * Becoming a slave on an alien planet.
 * The Cemetery Man unleashes zombies on you and Kim.
 * Goat kicking you off the edge of a cliff.
 * Zombies tearing you apart.
 * Landing in flames.
 * Uncles Ed captures you for Coach Rex.
 * Literally brainwashed into being obedient.
 * It is implied that you were eaten by a mountain lion.
 * Aliens attack the earth and the human race is destroyed.
 * The Cemetery Man turns everyone on earth, including you, into zombies.

Good Endings

 * One actually comes from letting Kim die
