The Lost Wild Dev Diary Details Its Dinosaur AI and Survival Horror Design

The Lost Wild is built around a particular idea of dinosaur horror: the creatures should feel like animals sharing a world with the player, not opponents waiting to be fought. That choice shapes Great Ape’s survival horror approach, where tension is supposed to come from figuring out how to live alongside dangerous creatures. It’s a more demanding premise than simply giving the player a weapon and a string of targets. The game has to make observation, distance, and timing feel consequential, even when the player isn’t directly under attack.

A new two-and-a-half-minute developer diary introduces the Brighton, UK-based team and its thinking behind the game. Game director Gary Napper says the developers are focused on the fear of being near these creatures and on what that experience would entail. For AI and gameplay programmer Lou Thorpe-Monaghan, that means treating dinosaurs as characters with their own existence: “We’ve always treated them as something that exists without the player being there.” That’s the guiding principle; the harder question is how consistently it can hold up once the player starts moving through the world and changing what the animals do.

Dinosaurs with lives beyond the player

That framing pushes against the familiar pattern of turning every creature into an enemy. The game’s trailers have shown players sneaking past dinosaurs and watching them behave when no player is present. Those glimpses suggest a different kind of encounter: the dinosaur may be occupied with its own activity, and the player has to decide whether to wait, hide, or risk moving closer. The intended tension comes from presence and unpredictability, with players deciding when to avoid the animals rather than assuming every meeting leads to a fight.

This is more significant than it looks. In many games, an animal can appear lifelike until the player’s actions reveal that it exists mainly to trigger a chase, attack, or combat sequence. The Lost Wild is asking players to believe the creatures have routines and reactions beyond those moments. That belief depends on behavior that feels legible enough to read but not so predictable that the animals become puzzles with one obvious answer. If you’re working in this space, you’ll recognize the design challenge: a creature needs to seem independent while still giving the player enough information to make a choice.

Great Ape is also grounding the creatures in scientific research. Art director and studio co-founder Tim Mehmet describes the work behind their design, including trips to places such as California’s Redwood Forest. The team’s attention to how dinosaurs look and behave is meant to support the game’s central fear: sharing unfamiliar territory with powerful animals. Research can help a design feel considered, but it can’t by itself make an encounter tense; movement, sound, distance, and the player’s limited options all have to reinforce the same impression. The forest visits point to the team’s interest in environments, too, where the setting can shape how a player spots or avoids a creature.

And this is the part most people overlook: “realistic” behavior isn’t automatically good horror. An animal that behaves plausibly but gives the player no readable cues may feel arbitrary, while a creature that telegraphs every move can lose its threat. The game has to find a middle ground between uncertainty and comprehension. A narrow opening to escape. A sound that makes the player reconsider a route.

An ordinary person in an extraordinary situation

Lead narrative designer Tom Hughes describes protagonist Sastia as an ordinary person suddenly thrown into a strange land among prehistoric creatures. “I would describe [protagonist] Sastia as a grounded, real person. She is someone who is an ordinary person who is plunged into the extraordinary.” Her perspective gives the survival premise a human scale: the player isn’t simply entering a combat arena, but confronting a world that operates on its own terms. That distinction matters because a protagonist framed as an expert fighter would change what danger feels like; an ordinary person makes caution and uncertainty easier to accept as part of play.

The premise also gives the game a way to connect its mechanics to character. Sneaking past an animal can express vulnerability as well as serve a practical purpose, while choosing not to provoke a confrontation can become a meaningful response to the situation. Here’s the thing: that only works if the player understands enough about Sastia’s circumstances to feel the pressure of each decision. The developer diary offers a description of her character, but the available details don’t yet show how the story will develop that perspective across the game. For now, the grounded protagonist is a useful foundation rather than proof that the narrative will make the premise land.

A long road to release

The Lost Wild was announced in 2022 with a planned 2024 release, initially for PC. Great Ape later confirmed a PS5 version, and a more recent trailer offered another look at the gameplay. The studio and publisher Annapurna Interactive now list a general 2027 launch window, with no firm release date announced. That history gives the new diary a particular role: it offers a clearer view of the team’s design priorities while the game remains some distance from a dated launch.

A broad window leaves plenty of uncertainty about when players will get to judge the finished experience. It also means the diary’s comments are best read as statements of intent, not a demonstration that every part of the design is settled. The footage and descriptions can explain what Great Ape wants dinosaurs to be, but they can’t establish how varied their behavior will feel over a full playthrough or how the game will balance stealth with other forms of interaction. That said, repeated attention to the same core idea gives readers a concrete standard to watch for in future footage.

What the design has to prove

The design’s success will depend on whether dinosaur behavior stays convincing under pressure. If the creatures feel like inhabitants rather than scripted obstacles, stealth and restraint can carry as much weight as confrontation. The challenge is sustaining that impression when the player needs to make progress, since a world that feels independent still has to respond clearly enough for the game to remain playable. A polished trailer can establish mood; repeated encounters will decide whether the central idea holds.

What this means for you as a viewer is simple: watch for how the animals behave when the player isn’t forcing an encounter, and whether their actions change the choices available. The premise has promise, but it also sets a high bar for the AI and level design to meet together. If Great Ape can make avoidance feel active rather than passive, the game’s restraint could become its strongest source of suspense. If not, the dinosaurs may still look convincing while functioning like familiar obstacles.
