I. Game Background
1.1 Setting the Scene
In 1993, billionaire John Hammond created a one-of-a-kind theme park on Isla Nublar: Jurassic Park. By extracting dinosaur DNA from amber and using genetic engineering to resurrect long-extinct prehistoric beasts, Hammond aimed to make the dream of humans and dinosaurs coexisting a reality.
But nature always finds a way to shatter human arrogance. An unexpected hurricane struck the island, causing the park's security systems to fail completely. Dinosaurs broke through their enclosures and escaped into every corner of the jungle—from the small Dilophosaurus to the fearsome T-Rex, and from packs of Velociraptors to the ferocious Tyrannosaurus, the entire island turned into a hunting ground overnight.
You play as a security officer hired by the park. Your mission is to venture deep into this out-of-control dinosaur paradise, assist trapped staff and visitors in evacuating, and survive the relentless dinosaur attacks. Powered by the Sega Model 2 board's impressive 3D graphics, you will traverse iconic Jurassic Park locations—the Visitor Center, jungle trails, laboratories, and the T-Rex paddock—blasting your way through with your light gun.
1.2 Development History
The arcade version of Jurassic Park was released by Sega in 1994 on the Model 2 hardware. Model 2 was Sega's second-generation 3D arcade board, following the Model 1, and was renowned for its smooth 3D polygon performance and cutting-edge texture mapping, powering Sega classics like Virtua Racing and Virtua Fighter.
This light gun shooter is based on Steven Spielberg's 1993 film of the same name. The movie was the highest-grossing film of its time (the first to surpass $1 billion globally), and its commercial impact was immense. After securing the rights, Sega decided to set the game after the key events of the film—which is the origin of the "rescue mission after the park's collapse" narrative perspective.
As one of Sega's major light gun shooters on the Model 2, this title paved the way for future Sega shooting series, such as The House of the Dead. The game's fluid 3D transitions, diverse enemy variants (from Velociraptors to Pteranodons and T-Rexes), and tense ammunition management established the design foundation for Sega's future light gun games.
II. Characters and Weapons
2.1 Playable Characters
The game supports 1-2 players simultaneously. Both characters are elite security personnel hired by the park—their mission is to protect survivors and eliminate dangerous dinosaurs amidst the chaos following the hurricane.
2.2 Weapon System
| Weapon | Description | Features |
|---|---|---|
| Standard Pistol | Default weapon, infinite ammo | Basic damage, suitable for common dinosaurs and fodder |
| Shotgun | Picked up in-game, high power at close range | Effective against fast enemies like Velociraptors |
| Assault Rifle | Picked up in-game, high fire rate | Mid-range suppression, ideal for clearing large groups |
| Grenade Launcher | Picked up in-game, high explosive splash damage | Best for large targets (like the T-Rex), but ammo is scarce |
2.3 Health System
Like most arcade light gun shooters, the game uses a health bar mechanism rather than "one-hit death." Taking damage from dinosaurs reduces your health, which can be restored using first-aid kits found in the environment. The game also features automatic checkpoints at key moments.
III. Level Walkthrough and Boss Strategy
There are 5 main levels, covering key areas of Jurassic Park.
Level 1: Park Entrance & Visitor Center
| Item | Details |
|---|---|
| Setting | Start at the park gate, cross the broken enclosure, and advance to the Visitor Center |
| Enemies | Dilophosaurus (spits venom), small Oviraptors, escaped small herbivores |
| Boss | No boss, but you will be surrounded by a pack of Velociraptors at the end—eliminate them quickly and protect the NPCs |
Level 2: Jungle Trail
| Item | Details |
|---|---|
| Setting | The destroyed jungle trail area. Velociraptors can jump out from the jungle at any time |
| Flow | Advance along the trail → broken perimeter fence → square outside the lab |
| Boss | Velociraptor Pack—3-5 Velociraptors attack simultaneously from different directions |
| Strategy | Prioritize shooting the heads of approaching Raptors (a hit can interrupt their pounce). Keep moving to avoid being surrounded |
Level 3: Laboratory & Hatchery
| Item | Details |
|---|---|
| Setting | Inside the park's genetic lab and dinosaur hatchery. Filled with incubation tanks and facility debris |
| Flow | Lab corridor → Hatchery hall → Genetic storage area → Encounter the first T-Rex |
| Boss | T-Rex - First Encounter—A battle outside the hatchery hall |
| Strategy | The T-Rex is massive; its weak point is its head. Prepare to dodge when it roars. Use the shotgun at close range for maximum damage |
Level 4: T-Rex Paddock
| Item | Details |
|---|---|
| Setting | The most dangerous area of the park—the T-Rex Paddock. The electric fences have failed |
| Flow | Paddock perimeter → Inside the T-Rex nest → Emergency evacuation tunnel |
| Enemies | Large numbers of Velociraptors + Pteranodons (aerial attacks) |
| Boss | T-Rex - Final Battle—The T-Rex is enraged and chases the player to the edge of the paddock |
| Strategy | Dodge to the side when the T-Rex lunges. Use oil drums and explosives in the environment for extra damage. The T-Rex will retreat to the depths of its nest after taking enough damage—this is your final window to deal damage |
Level 5: Helicopter Evacuation
| Item | Details |
|---|---|
| Setting | The park's helipad. The rescue helicopter has arrived, but a swarm of Pteranodons appears in the sky |
| Flow | Helipad → Aerial gunfight (shoot pursuing Pteranodons from the helicopter door) |
| Boss | Pteranodon swarm + Final T-Rex Assault—The T-Rex appears one last time as the helicopter prepares to take off |
| Strategy | Pteranodons have low health but are fast; prioritize the leaders. The final T-Rex attack requires heavy firepower to drive it back before takeoff. After clearing, you fly off into the sunset as the island burns behind you |
IV. Gameplay Tips
4.1 Basic Survival
- Ammo Management: The pistol has low damage but infinite ammo—don't waste shotgun shells on small dinosaurs; save heavy weapons for boss fights.
- Weak Point Targeting: All dinosaurs have a weak point on their head; headshots deal roughly double the damage of body shots.
- Use the Environment: Explosives (oil drums, electrical boxes) can be used to wipe out packs of Velociraptors.
- Co-op Coordination: Divide tasks during boss fights—one player draws the T-Rex's attention while the other focuses on headshots.
4.2 Advanced Co-op Tips
- Firepower Distribution: One player uses the assault rifle to clear fodder, while the other keeps the shotgun ready for the boss.
- Health Management: Avoid having both players at low health. When one player is in danger, the other should actively draw fire.
- Ammo Sharing: Ammo supplies are limited; prioritize giving ammo pickups to the player carrying the grenade launcher.
4.3 Environmental Interactions
| Object | Effect |
|---|---|
| Electrical Box | Shoot to electrocute nearby dinosaur packs |
| Oil Drum | Explode for area-of-effect fire damage; excellent against Velociraptors |
| Gas Pipe | Shoot leaking pipes to create explosive gas zones |
| Supply Crate | Drops ammo, first-aid kits, or temporary weapons |
| Trapped NPC | Eliminate approaching dinosaurs before they attack the NPC for bonus points |
4.4 Difficulty Strategies
| Difficulty | Enemy Speed | Recommended Strategy |
|---|---|---|
| Normal | Moderate | Focus on headshots with the pistol; save heavy weapons for bosses |
| Hard | Fast | Prioritize picking up the assault rifle; maintain mid-range suppression |
| Expert | Very Fast | Perfect co-op coordination; use the shotgun as your primary weapon |
V. Trivia
5.1 A Pioneer of Sega Model 2 Light Guns
Jurassic Park was one of Sega's early light gun shooters on the Model 2 board. The 3D performance of the Model 2 made dinosaur movements much more fluid and realistic than traditional 2D light gun games. Sega later released the more famous and terrifying The House of the Dead (1996), with some of the same team members involved.
5.2 A 1993 Movie Phenomenon
The 1993 Jurassic Park film sparked a global dinosaur craze. The 1994 arcade release capitalized on this momentum perfectly—while the game doesn't retell the movie's story directly, it acts as a "parallel adventure," allowing players to enter the film's world and experience the fear and excitement of being hunted by dinosaurs.
5.3 The Unique Charm of Light Gun Shooters
Unlike the fighting games and side-scrollers common in arcades at the time, light gun shooters offered a unique sense of immersion. Holding a light gun and pulling the trigger provided tactile feedback. This "aim-shoot-dodge" loop offered a fresh experience distinct from traditional joystick controls. Along with Virtua Fighter, Jurassic Park showcased the massive potential of the Model 2 board for "immersive arcade experiences."
5.4 Technical Breakthroughs of the Model 2 Board
Sega's Model 2 board was a major milestone in arcade technology between 1993 and 1996. It used multiple Intel i960 processors working in tandem to support 3D rendering at up to 60 frames per second. Jurassic Park fully utilized the Model 2's 3D polygon capabilities to build volumetric dinosaur models—the T-Rex's roar, the Velociraptor's high-speed sprint, and the Pteranodon's aerial circling—all of which were impossible in 2D games of that era.
