For traveling, the player moved one square at a time via a compass that had the following directions: north, northwest, west, southwest, south, southeast, east, and northeast. For each level, the player had 20 moves they could make these being travel, wait and attack. The map was 17X10 squares with the square that Big Al was on being yellow while his mother was red and the nest was brown. Since fitness serves as the health bar of the game, fitness could be lost from an animal attacking the player or from a counterattack against the player. The older Al became the more energy he would use and need to replenish. The player had to keep eating to stay fit as energy is lost from even moving on the map and to add more weight to gain a level. Reasonably, given its the later, losing all energy or fitness would result in Big Al's death. Weight served as the progress bar for the player's level and fitness served as a health bar. The player had three statistics, score, weight, and fitness. At the final level, Adult, Big Al's objective is to find mates to breed with and is able to defeat even larger animals, including adult Allosaurus. When the player reaches Juvenile and subsequently Sub-adult, their mother disappears and the player can defeat larger animals like Dryosaurus and Ornitholestes as well as being able to consume dinosaur eggs. At this level, the young Al can only hunt small animals such as centipedes, scorpions, and lizards. As a hatchling, the player starts out in their nest and the game recommends to follow Al's mother as her large size can scare away larger predators. There are four levels that Al has, starting as a hatchling growing into a juvenile, subadult and adult. You play the Allosaurus named Big Al with the objective of simply surviving in Late Jurassic North America.
