Jurassic World Evolution 2: Complete Guide

A park-management guide for Frontier's dinosaur sim: which mode to start with, building a profitable park, keeping dinosaurs comfortable, managing scientists and research, dealing with storms and breakouts, and getting 5 stars in Campaign, Chaos Theory, Challenge and Sandbox.

Researched September 2026 — current as of Update 1.11.3 (June 2025). The sequel, Jurassic World Evolution 3, launched on 21 October 2025; JWE2 is still fully playable but no longer receives feature updates. Live games change; check the linked sources if something differs.

Quick Start

• Play the Campaign first. It's a guided tutorial across several US locations, introducing systems one by one. Then move to Chaos Theory.
• Research and expeditions unlock everything. Dig sites (via the Expedition Center) give fossils; fossils give genome progress; genome at a certain level lets you incubate a species.
• Hire a balanced scientist team. Scientists have Logistics, Genetics and Welfare stats. Match the right scientist to the job, and rest them before they get tired and go on strike.
• Build enclosures for the dinosaurs' needs, not yours. Every species has needs for forest, open grassland, water, and social group size. Check the dinosaur's info panel before hatching.
• Separate herbivores and big carnivores. Big predators will hunt and kill herbivores sharing their territory.
• Power everything. Most buildings need power. Build power stations and substations early and route power lines.
• Guests pay for amenities and viewing. Place viewing galleries, shops, restaurants and hotels near attractive dinosaur habitats.
• Keep a Ranger Station and Response Facility near every enclosure. Rangers feed, resupply, and heal; the Response Facility tranquilizes and relocates escaped animals.
• Watch the weather. Storms damage fences and can knock out power. Prepare with generators and repairs.
• Save before big moves. Hatching a big carnivore or releasing two species together can go wrong quickly.

Game Modes

Mode | What it is | Best for

Campaign | Story set after Fallen Kingdom; containing dinosaurs loose across the USA | Learning the systems

Chaos Theory | "What if" scenarios based on the Jurassic Park and Jurassic World films | Challenge and fan service

Challenge | Timed park-building with difficulty tiers and constraints | Testing mastery

Sandbox | Unlimited creative mode with custom settings | Building dream parks

Iconic characters appear: Dr. Ian Malcolm (voiced by Jeff Goldblum) and Claire Dearing (voiced by Bryce Dallas Howard).

Tip: Chaos Theory missions unlock content for Sandbox. Play them to unlock more species and buildings.

Core Systems

Scientists

Scientists are essential. Each has stats in:

• Logistics: Speeds up construction/building upgrades and expeditions.
• Genetics: Speeds up synthesis and genetic modification.
• Welfare: Speeds up healing and disease treatment.

Every action drains their energy. Tired scientists become unhappy, and unhappy scientists may sabotage your park. Rest them regularly by unassigning them for a while.

Research

Research unlocks new buildings, upgrades, dinosaur modifications, and amenities. Priorities in a new park:

• Power upgrades and additional scientists.
• Ranger and response capabilities.
• Guest amenities and viewing galleries.
• Dinosaur feeders and enrichment.
• Genetic modification (traits and lifespan).

Expeditions and fossils

• Send teams to dig sites from the Expedition Center.
• Returned fossils can be extracted to add to a species' genome, or sold.
• A species can be incubated once its genome reaches the required level. Higher genome percentage means a healthier, more viable dinosaur.

Hatching (Hatchery)

• Incubation happens at the Hatchery; you choose the species, then pick genome modifications before releasing the animal into its enclosure.
• You can modify genomes to improve traits such as lifespan, resistance to disease, attack/defense, and appearance.
• Check viability: low-viability embryos may die in incubation.

Dinosaur welfare

Every species has needs:

Need | What to provide

Food | Feeders or live prey (goats), plants for herbivores

Water | A lake or water source in the territory

Territory | Forest and open ground ratios in their territory

Social | Correct population size, compatible species

Comfort | All the above plus no threats

Dinosaurs that are uncomfortable may break fences and escape.

Territory

Territory is the area each animal considers home. Two animals whose territories overlap may fight, share, or ignore each other depending on species relationships.

• Herbivores: Most can live together. Some species dislike others; check the relationship info.
• Carnivores: Most are solitary or small groups. Some pack hunters (like Velociraptor) need their pack.
• Aviaries and lagoons: Flying reptiles need aviaries; marine reptiles need lagoons.

Diseases and injuries

Diseases spread via contaminated feeders and water. Rangers and the Paleo-Medical Facility handle treatment. Keep feeders stocked and check dinosaurs' health often.

Building a Profitable Park

Layout principles

• Build guest zones around attractions. Guests pay for amenities near the dinosaurs they want to see.
• Keep guest zones compact. Long walks lower guest satisfaction.
• Use viewing galleries, platforms and Gyrosphere rides to let guests see dinosaurs without direct exposure.
• Offer a mix of guest types. Different guests prefer different dinosaurs (herbivores vs carnivores) and amenities. Balance your park to satisfy several groups.

Money

• Admission revenue grows with park rating.
• Amenity revenue depends on amenity quality and guest traffic.
• Selling fossils is a good early money source.
• Park rating drives guest numbers, so every star you gain compounds your income.

Guest safety

• Build emergency shelters in guest areas; guests hide there during breakouts.
• Keep strong fences around carnivores. Upgrade to higher-security fences for large predators.

Opening Build Order (Challenge and Sandbox)

A reliable first 30 minutes for a fresh map with limited money:

• Pause and survey. Find flat ground near water with some forest. That spot becomes your first herbivore enclosure.
• Power first. Place a power station and a substation that covers the area you'll build in.
• Hire scientists. Cover each stat (Logistics, Genetics, Welfare) with at least one decent scientist.
• Expedition Center and a dig. Start fossil income right away; fossils fund the early game when sold, or build genome progress.
• Hatchery plus a herbivore enclosure. Start with a cheap, sociable herbivore that tolerates a group. Add a feeder and make sure there is water inside the fence.
• Ranger Station. Place it close enough to reach your enclosures fast.
• Guest zone. A short path from the entrance to a viewing gallery on your enclosure's edge, then one food and one drink amenity, adding more guest facilities as research unlocks them.
• Research the next upgrades while money builds: more scientists, better power, and stronger fences.
• Second enclosure and diversity. A different herbivore group, then your first small carnivore only when your Response Facility and fences are ready.
• Shelters and backup power before your first big predator.

Money rule of thumb: Always keep a cash buffer for emergency repairs. A storm that knocks down a fence while you're broke is how parks collapse.

Handling Emergencies

Emergency | What to do

Storm | Repair damaged fences; ensure backup power

Fence breach | Response team tranquilizes and relocates; close nearby shelters

Disease outbreak | Isolate infected animals; treat with Paleo-Medical Facility

Power outage | Build backup generators; repair damaged power lines

Scientist strike | Rest scientists; improve their satisfaction

Tip: Upgrading Ranger Stations and Response Facilities speeds up all of these.

Species Tips

• Herbivores such as Triceratops, Brachiosaurus, Parasaurolophus, Stegosaurus and Ankylosaurus are forgiving and popular. They're great early attractions.
• Big carnivores like Tyrannosaurus rex, Giganotosaurus and Allosaurus give huge attraction ratings but need strong fences, space and feeders.
• Pack hunters like Velociraptor need their pack size met.
• Flying reptiles (Pteranodon, Quetzalcoatlus) need aviaries.
• Marine reptiles (Mosasaurus, Plesiosaurus) need lagoons.
• Hybrids (e.g., Indominus rex) are high risk, high reward.

DLC Overview

JWE2 received many DLC packs through 2024. The notable ones:

• Dominion Biosyn Expansion (14 June 2022): A new campaign set in Biosyn Valley from Jurassic World Dominion, with four species including Pyroraptor and Therizinosaurus.
• Dominion Malta Expansion (8 December 2022): A Malta black-market campaign that introduces the Dinosaur Exchange trading mechanic and four species including Atrociraptor.
• Species packs themed on the Early and Late Cretaceous, marine reptiles, feathered species and more.
• Park Managers' Collection Pack (16 May 2024): Megalodon, Microceratus, Segisaurus, Thanatosdrakon, plus a new T. rex skin.

Update 1.11.2 (June 2025) added free scenery celebrating JWE3's announcement: Dinosaur Sculptures (T. rex, Triceratops and Stegosaurus families) and Dinosaur Integration Network signs and diorama. Update 1.11.3 made them placeable on paths.

Common Mistakes to Avoid

• Hatching a big carnivore too early. Without strong fences, response teams, and shelters, it's a disaster.
• Ignoring dinosaur needs. Unhappy dinosaurs break out.
• Overworking scientists. Strikes and sabotage wreck progress.
• Underpowering the park. A power outage can disable fences.
• Too many species in one pen. Relationships and social limits matter.
• Neglecting guest variety. A park with only herbivores attracts only some guest types.
• Forgetting to save before experimenting.

Advanced Tips

• Use terrain tools to create forest/grass/water ratios exactly as needed.
• Build "mega-enclosures" for compatible herbivores to boost attraction and save space.
• Aviary and lagoon attractions can raise park ratings quickly.
• Genome modifications can increase lifespan and resistance to disease.
• Sandbox settings let you disable disease, breakouts, and other threats if you just want to build.
• Plan paths and power corridors before placing enclosures to avoid later demolition.

FAQ

Is JWE2 still worth playing now that JWE3 is out? Yes, especially if you already own DLC. JWE3 adds juvenile dinosaurs, breeding and modular building, but JWE2's campaign and Chaos Theory mode remain great.

Can dinosaurs breed in JWE2? No. Natural breeding and juveniles are new in Jurassic World Evolution 3.

How do I unlock more species in Sandbox? Play Campaign, Chaos Theory and Challenge modes; many species and buildings unlock through them.

Why do my dinosaurs keep breaking out? Usually unmet needs (food, water, territory, social), storms, or weak fences. Check the comfort breakdown.

How do I make money early? Sell spare fossils, keep your first herbivores comfortable, and build a small cluster of amenities near your first herbivore enclosure.

What's the best guest-rating strategy? Mix species, cover multiple guest types, and put viewing galleries and amenities close to attractions.
