Afterthought Games used The Isle DevBlog #70 to lay out a broad progress update across HordeTest, the Hatchery, animation, audio, and the systems work feeding into Evrima.
HordeTest, the Hatchery, and more creature work
Ariel said the team spent the month cleaning up issues found during HordeTest and made a small nesting change. Once a player takes an egg, the dinosaur will now hatch on its own after a while, which should keep eggs from being tied up forever when someone walks away from them. He also returned to the dinosaur camera system, starting with the more unusual body shapes before moving through the rest of the roster.
VisualTech48 said the team folded several older GUTS locations into a new multi-story facility. The Hatchery now combines the necropsy area and incineration pit into a brutalist science building with large halls, rooms for hatching and feeding, and different paths for juvenile animals and smaller creatures.

Wedge’s audio update focused on three dinosaurs in particular. Camarasaurus is still going through concepting and iteration for its first Evrima appearance, with the team testing heavier bass and sharper percussive details to sell its size. Baryonyx juvenile vocals are being revised, and the team said the tonal gap between juveniles and adults made a subadult sound set necessary. Avaceratops is also getting a fresh vocal pass built around elk bugles and other source material.
KissenKitten said the animation team is close to finishing avaceratops sparring animations and shared more progress on parasaurolophus. The studio also said Ovi, Bary, and Camara are waiting on their HordeTest debut, with their animation work done aside from fixes and small additions.
In the director’s commentary, the team said the current HordeTest build should be the final one before it moves to Evrima. A quick turnaround is planned for the next HordeTest at the end of the week, and Austroraptor will be available right away. Hillsliding, destructible foliage, updated skin patterns and palettes, and one more wound-system pass are also part of the near future, along with the next playable batch after Spinosaurus. Internally, that group is called the “Nebulous Five”: Shantungosaurus, Ankylosaurus, Homalocephale, Megalania, and Giganotosaurus.
