Jurassic World Evolution 3 is gearing up for its first post-launch expansion, and fans have plenty of reasons to watch the clock. The Wetlands Pack DLC brings new environments, new dinosaurs, and a fresh set of park-building challenges, arriving worldwide alongside a free update for all players. If you want to know exactly when you can start building swamps, managing semi-aquatic predators, and designing marsh-filled enclosures, this breakdown gives you the full timeline and feature rundown.
Jurassic World Evolution 3 Wetlands Global Release Date and Countdown
The Wetlands Pack DLC is set to launch with a free content update on December 9, becoming the first major expansion since full release. The rollout follows a global schedule rather than a staggered regional release.
Global rollout: December 9, 2025
Expected launch window based on prior rollout times:
Metroid Prime 4: Beyond – Nintendo Switch 2
- 7am PT
- 9am CT
- 10am ET
- 3pm UTC
- 4pm CET
What the Wetlands Pack Adds to the Game
The expansion leans into environments that blend water and land, focusing on biome-driven gameplay. Whether you’re a builder who thrives on creative terrain design or a management-focused player planning balanced ecosystems, Wetlands introduces tools that affect the way dinosaurs behave, interact, and survive.
New species included in the DLC
The Wetlands Pack introduces three prehistoric family units, each suited to marsh-oriented habitats and each bringing distinct behavioral needs:
| Species | Type | Notes |
|---|---|---|
| Irritator | Semi-aquatic carnivore | Hunts both fish and dinosaurs, full family grouping included |
| Austroraptor | Carnivorous raptor | Feathered, fish-adapted, thrives near feeders and shallow water |
| Hypsilophodon | Herbivorous biped | Fast-moving grazer, suited to swamp vegetation and group enclosures |
These dinosaurs do more than just add variety. Housing multiple wetland-ready species will push your understanding of territory, dietary needs, and mixed-environment cohabitation. The Irritator, in particular, is poised to be a fan favorite thanks to its land-and-water hunting flexibility.
New Biome and Scenery Tools
The new Wetlands biome is at the core of the DLC. You’ll be able to build enclosures with heavier water coverage, muddy textures, and marsh-driven foliage density. The biome is more than cosmetic—it influences dinosaur behavior and comfort levels, meaning players need to think carefully about water depth, land access, and food zones to maintain stability.
The Wetlands Pack also includes ecosystem customization options, allowing fine-tuned control over terrain feel, foliage saturation, and view aesthetic. Building a park that looks and functions like a real swamp becomes a genuine design challenge.
Free Update Launching Alongside the DLC
Even if you’re not purchasing the Wetlands Pack, you aren’t left out of the party. The expansion arrives simultaneously with a free base-game update, which adds quality-of-life upgrades and creative sandbox features.
Free content includes:
- New biome options for Sandbox mode
- Updated scenery improvements for photography and visual composition
- Additional island generator and environment modification tools
- Gameplay and performance optimization updates
This means every player receives new ways to build—DLC or not. Those who own the pack simply unlock the full ecosystem experience layered on top.
Should You Get the Wetlands Pack?
If you enjoy designing parks that feel more alive and biologically reactive, the Wetlands Pack expands gameplay in ways the base biome set doesn’t. The addition of semi-aquatic hunting, specialized vegetation zones, and herd-driven species behavior reshapes how players manage space and resources.
The appeal isn’t just visual. Wetlands introduces habitat complexity that rewards strong layout planning and penalizes careless enclosure design. If you love strategy-aware micro-management, this DLC delivers meaningful new systems to play with. Play Now!
