C1: The Hidden Shrine of Tamoachan (1980)

From the publisher:

"This module was originally used for the Official Advanced Dungeons & Dragons tournament at Origins '79, and is the first in another new series of modules from TSR, the Competition Series. This module contains a challenging setting as well as an original scoring system and an assortment of pre-rolled characters for adventuring. The module may thus be used for private competition among players, or as a separate, non-scored adventure! also include herein are background information, a large-scale referee's map, referee's notes, and new monsters and descriptions for an added taste of excitement.

This module is meant to stand on its own, and includes areas on the map where Dungeon masters may add their own levels."

Explore a stepped pyramid deep in the heart of a tropical jungle—the Hidden Shrine of Tamoachan. The characters must penetrate this Mayan-style temple, which is full of tricks and traps.

The shrine is an ancient Mayan/Aztec pyramid, and the module uses names, monsters, and characters based on that period. It also includes an illustrated booklet with fifteen pictures depicting various parts of the shrine to be shown to the players at the appropriate time. Also included are three premade characters for use if the scoring system is used.
