This wiki page is the overview. It covers the release details, the premise, the four chapters, the creatures, the collectibles, and the questions new players ask most often. The detailed routes live in the walkthrough.

Release details

The game is built in Unreal Engine and runs on Windows. There is no native macOS or Linux version. The Steam Deck rating is Playable, with small interface text and limited external controller support.

What is Terrible Lizards about?

Jordan, a college student driving from Chicago to Los Angeles, breaks down on Route 66 in New Mexico. The nearest help is Dalton's Dinos, a roadside attraction built around a rare dinosaur fossil. The park is closed, the phones are unreliable, and the owner is missing.

Stella, a paleontologist and friend of the owners, guides Jordan over a headset. The park's son, DJ, is somewhere underground. The deeper Jordan goes, the clearer it becomes that the park's mascots and its living dinosaurs are connected.

The story is set on September 19, 1992. The period detail is deliberate: the park is a monument to 1990s dinomania, and the technology is analog. The game uses notes, audio tapes, and FMV sequences to fill in the park's history.

The four chapters

Each chapter follows the same design loop: explore a space, learn a mechanic, then get tested by a chase, a hunt, or a navigation puzzle. The chapters are sequential, and level select unlocks after the credits.

The creatures

The game has three main dinosaurs:

• Brontosaurus. A large herbivore that patrols the Digsites. It is not a boss with health; it is a route obstacle. You redirect it with power and dynamite.
• Allosaurus. The main hunter of Chapter 3. It can cut through rooms and interrupt its own charge if you stare at it briefly. The fuse panel hunt is the hardest encounter in the game.
• Dilophosaurus Hybrid. The final creature. It combines a dinosaur body with a humanoid silhouette, and it hunts Jordan through the Deep. The design was originally a human-raptor concept.

The park also has four Paleo Pal mascots: Benji, Alistair, Stephanie, and Dennis. Pterry was added later in production. The mascot suits are a deliberate horror element, and the game treats them as part of the creature cast.

Gameplay

Terrible Lizards has no combat. The movement verbs are run, sprint, jump, slide, mantle, wall run, swing, and bounce. Aerial control is strong, mantles are generous, and checkpoints are frequent.

The game's structure mixes:

• Platforming. Wall runs, swings, and timed jumps.
• Chases. Scripted routes with a dinosaur behind you.
• Hunts. Free-roam spaces with a patrolling creature.
• Exploration. Offices, tents, and caves with notes and tapes.
• Light puzzles. Keypads, fuses, generators, and power loops.

The game is not a survival horror game. You cannot fight, hide permanently, or manage resources. The horror comes from the chase sequences and the mascot imagery.

Collectibles and achievements

There are five collectible categories:

• 16 amber samples.
• 24 audio tapes.
• 97 notes.
• 4 Paleo Pal statues.
• 4 stuffed animals with pedestals.

The achievements are split between story progress, collectibles, and small interactions. The full list is in the achievements guide. The collectible totals and confirmed locations are in the collectibles guide.

Amber unlocks New Game Plus modifiers in groups of four. The stuffed animals unlock the You Go Here achievement and a short bonus sequence.

Length and replay

The main story is 6 to 10 hours. A fast run can finish under 6 hours, and a completionist run can reach 12. The game has four chapters, level select, and New Game Plus with four modifiers: body-cam, slippery surfaces, stop-moving death, and low gravity.

The game does not have multiplayer, co-op, or a level editor. The arcade in Chapter 1 is decorative and cannot be played.

Reception and performance

At the time of writing, the Steam version has 413 reviews and an 82% positive rating. The game's launch window was short, and the review count is still growing.

The PC version runs on Windows 10 and 11. The minimum GPU is a GTX 1050 or RX 560; the recommended GPU is an RTX 2080 or RX 6800 XT. The install is about 17 GB, and the store lists 25 GB of required space. The system requirements guide has the full tables.

The Free To Play tag

The Steam page lists Free To Play as a genre, but the game is paid. The Steam API reports is_free: false, and the store page shows a $24.99 price with a launch discount. The tag is a metadata error, not a secret free version.

If you see a site claiming the game is free, check the official store page. The game is included with Game Pass, which is a subscription, not a free-to-play model.
