Jurassic Park is based on the novel and film of the same name. Following a computer system failure, Dr. Alan Grant and others become trapped on an island theme park populated with dinosaurs.
The player controls Grant, and begins the game armed with a cattle prod, although the game also features five other weapons: tranquilizer gun, shotgun, bolas, gas grenade launcher, and missile launcher. The game features seven different dinosaur enemies, as well as giant dragonflies. The player is given five lives, and two continues when all lives are lost. Grant's health is represented by a red health bar. Food and first-aid kits located throughout the game can replenish the player's health.
Motion sensors set up around the island allow characters in the game to communicate advice to the player, although some advice is deliberately malicious. If Grant loses a life, the player is restarted at the last motion sensor with which Grant came into contact. Mr. DNA, a character from the film, provides dinosaur facts to the player if the game is paused or remains idle for too long. The player must open and close multiple gates to travel around the island. The game's music changes depending on the player's location in the park. The player is also required to collect dinosaur eggs throughout the game.
The game's exterior portion, played from a bird's-eye view, consists of a maze that is made up of jungle trees. The game switches to a first-person perspective when the player enters a building. The player must collect ID cards belonging to characters on the island in order to access certain rooms. Other rooms are completely dark and require night vision goggles to enter. Jurassic Park supports the Super NES Mouse when playing first-person sequences or operating computer terminals.
To win the game, the player must complete several objectives, starting with powering up a computer to re-activate the park's motion sensors. Once activated, the player's short-range motion sensor can detect nearby dinosaurs. Subsequently, the player must determine how raptors are infiltrating the park's visitor center and stop them; prevent raptors from escaping to the mainland on a supply ship; and find the raptors' nests in underground volcanic tunnels and destroy them with a nerve gas bomb. The final objective requires the player to locate a communications center to contact a helicopter, and then reach the helipad to be rescued. The game does not utilize a password feature. The player, therefore, is required to play through the entire game in a single sitting.
