Clawed Demo Puzzle Solutions

Environmental puzzles gate most of Prehistoria’s interior in the Clawed Steam demo. Unlike combat encounters, these locks punish backtracking: missing the fossil before visiting the museum wastes a full loop, and entering the underwater segment without noting red light order can drown a co-op team. This page isolates the three puzzle clusters players search most - museum fossil / south tunnel*, underwater buttons, and fuse / wrench maintenance - with prerequisites, solution steps, and links back to the broader Demo Walkthrough and Key Locations checklist.

Museum fossil and south tunnel key

Prerequisites: Museum key from the staff center; fossil from the toilet block (not inside the museum gift shop). Without both, the south tunnel lock will not complete.

Step-by-step:

1. Enter the museum using the staff center key. Clear ground-floor galleries so Utah Raptors cannot interrupt the puzzle room during input.
2. Locate the fossil display or security panel tied to the south tunnel - community reports reference placing or registering the fossil from the toilet block at this station. Interact with the prompt until the display acknowledges the specimen.
3. Watch for a secondary indicator: a shutter opening, a lit corridor sign, or a desk drawer releasing the south tunnel key. Pick up the key immediately and assign a co-op player to hold it - keys do not always respawn in shared worlds.
4. Exit via the south tunnel route toward maintenance-adjacent corridors. This shortcut connects museum lore space to the Spinosaurus maintenance loop described on Prehistoria Overview.

Common mistakes: Running the museum before the toilet block; dropping the fossil during a raptor chase; splitting the team so the player with the fossil is trapped outside the keyed door. Fix by regrouping at the staff center and re-walking the fossil path together.

Underwater red-light button route

Prerequisites: Progress through ranger station or adjacent checkpoint until the aquatic segment unlocks; assault rifle or shotgun recommended for surface threats before submerging.

Concept: The underwater section uses red lights as a breadcrumb trail. Deviate and you face Deinosuchus or Megalodon pressure - see Dinosaur Tier List. The puzzle is navigation-first; button inputs appear at lit nodes along the route.

Step-by-step:

1. Enter the water at the marked pool, dock breach, or service sluice indicated on Demo Route. Equip minimal inventory if the game slows swimming when overloaded.
2. Submerge and follow red lights in sequence. At each light, look for a button, valve, or pull chain on nearby walls, pipes, or sunken consoles. Press in the order the lights lead you - skipping a node often resets the gate ahead.
3. Co-op: one player advances lights while another watches the surface for ripples. Voice call each button number or compass direction to avoid duplicate presses.
4. Surface only at the final red cluster; the game typically deposits you in a tunnel leading toward the maze or ferry approach. If air management exists in your build, do not linger between nodes.

Common mistakes: Surfacing mid-route; fighting aquatic predators instead of returning to the last red light; missing a side alcove button obscured by kelp or rust geometry. If stuck, backtrack to the previous lit node and scan 180 degrees before blaming a bug.

Fuse panel and wrench maintenance puzzle

Prerequisites: Maintenance shed key from opposite the Spinosaurus circle; enter the shed for the fuse; locate the wrench near its use point (often in the same maintenance wing rather than the shed interior).

Concept: A disabled door, elevator, or pump station requires inserting the fuse into a panel and tightening or coupling with the wrench at a nearby valve or bolt interaction. This is the demo’s clearest “fetch tool, return to machine” loop.

Step-by-step:

1. After retrieving the fuse from the maintenance shed, identify the panel on your HUD or map ping - usually between the Spinosaurus loop and ranger station connector.
2. Insert the fuse into the empty slot. The panel may spark or show a partial green light; the puzzle is incomplete until the wrench interaction finishes.
3. Find the wrench at the reported use point - search within one room radius of the panel for a highlighted pipe, bolt, or wheel. Complete the interaction to restore power.
4. Pass through the newly opened gate toward the ranger station or underwater entry depending on your demo state. Mark fuse completion on Key Locations so co-op teammates do not search the shed again.

Common mistakes: Using the wrench before inserting the fuse; carrying the fuse into a raptor ambush and losing it on death in Survival mode; ignoring Spinosaurus patrol timing when crossing back to the panel.

Puzzle dependency chart

Puzzle	Required items	Unlocks
Museum fossil	Museum key, toilet block fossil	South tunnel key, shortcut to maintenance wing
Underwater red lights	Prior story progress, swimming segment	Maze approach, ferry branch tunnels
Fuse and wrench	Shed key, fuse, wrench	Powered gate toward ranger / aquatic zones

Co-op communication template

Assign callouts: “Fossil runner” for toilet block retrieval, “Museum holder” for keyed door, “Light diver” for underwater nodes, “Panel tech” for fuse and wrench. Rotating roles reduces fatigue on repeated demo attempts for content creators or achievement hunters.

When to read other pages

If puzzles are solved but combat fails, study Weapons Tier List for shotgun versus assault rifle roles. If you lack keys entirely, skip back to Key Locations rather than guessing button codes. For full sequential narration, keep Demo Walkthrough open on a second monitor.

Flatrock Games may rebalance puzzle hints before full release on Steam - verify fossil and fuse placements after major demo patches and update your personal notes accordingly.
