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 1. **Play the Campaign first.** It's a guided tutorial across several US locations, introducing systems one by one. Then move to Chaos Theory. 2. **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. 3. **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. 4. **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. 5. **Separate herbivores and big carnivores.** Big predators will hunt and kill herbivores sharing their territory. 6. **Power everything.** Most buildings need power. Build power stations and substations early and route power lines. 7. **Guests pay for amenities and viewing.** Place viewing galleries, shops, restaurants and hotels near attractive dinosaur habitats. 8. **Keep a Ranger Station and Response Facility near every enclosure.** Rangers feed, resupply, and heal; the Response Facility tranquilizes and relocates escaped animals. 9. **Watch the weather.** Storms damage fences and can knock out power. Prepare with generators and repairs. 10. **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: 1. Power upgrades and additional scientists. 2. Ranger and response capabilities. 3. Guest amenities and viewing galleries. 4. Dinosaur feeders and enrichment. 5. 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: 1. **Pause and survey.** Find flat ground near water with some forest. That spot becomes your first herbivore enclosure. 2. **Power first.** Place a power station and a substation that covers the area you'll build in. 3. **Hire scientists.** Cover each stat (Logistics, Genetics, Welfare) with at least one decent scientist. 4. **Expedition Center and a dig.** Start fossil income right away; fossils fund the early game when sold, or build genome progress. 5. **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. 6. **Ranger Station.** Place it close enough to reach your enclosures fast. 7. **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. 8. **Research the next upgrades** while money builds: more scientists, better power, and stronger fences. 9. **Second enclosure and diversity.** A different herbivore group, then your first small carnivore only when your Response Facility and fences are ready. 10. **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. --- ## Sources - [Jurassic World Evolution 2 on Steam](https://store.steampowered.com/app/1244460/) - [Jurassic World Evolution 2 (Wikipedia)](https://en.wikipedia.org/wiki/Jurassic_World_Evolution_2) - [JWE2 Update 1.11.2 and 1.11.3, Park Managers' Collection Pack (Steam news)](https://store.steampowered.com/news/app/1244460) - [Jurassic World Evolution 3 on Steam](https://store.steampowered.com/app/2958130/Jurassic_World_Evolution_3/)
