On Thin Ice fight walkthrough: Chapter 4 Route

On Thin Ice fight walkthrough guidance is most useful in Chapter 4, where Kate and Murphy enter Sticks’ hideout during the blizzard. The chapter combines environmental searching, code puzzles, stealth movement, item combinations, and a three-round fight. Make progress carefully because several clues appear only after you clear snow, move objects, or inspect the surrounding signs.

Video Highlights:

  • The route from the snowy entrance to Sticks’ hidden base
  • The gate code and five-marker drone sequence
  • Murphy’s bridge rescue and the ring-matching puzzle
  • The final confrontation and fight-manual strategy

The chapter begins outside the hideout. Clear the snow and inspect the signs before trying to force the gate. The bullet-hole markings are not decorative; they connect each sign to a number used in the lock.

Chapter AreaMain ObjectiveImportant Clue
Snowy entranceClear the blocked approachSix signs and a rubble pile
Metal boxReveal the gate lockVodka removes the ice
Gate lockEnter the access codeBullet holes match 99, 12, and 24
Drone fieldCollect five markersMove between patrol openings
Hidden baseReach Murphy and continue insideBridge materials and ring clues

The correct gate code is 991224. The sequence comes from three signs:

  • One bullet hole corresponds to 99.
  • Two bullet holes correspond to 12.
  • Three bullet holes correspond to 24.

Enter the numbers in that order. If the lock does not open, revisit the signs and confirm that you are counting bullet holes rather than other marks on the posters.

Search Order

Clear snow first, collect the vodka, and inspect every sign before entering the code. The puzzle becomes much easier when the clues are read in numerical order.

Gate, Drones, and the Hidden Entrance

After opening the gate, Kate and Murphy must cross the drone area. This is a movement puzzle rather than a combat encounter. The goal is to gather five markers while avoiding the drones’ visible patrol routes. Move only when a drone has created enough space, then pause to observe its next pass.

The safest approach is to treat each marker as a checkpoint. Do not rush toward the next object immediately after collecting one. First identify the nearest safe position, then wait for the drone to move away.

1

Enter the Drone Area

Move through the gate and identify the full patrol pattern before collecting anything. Note which lanes are crossed by the drones and which spaces remain safe for a short time.

2

Collect the First Markers

Take the closest markers when the nearest drone is moving away. Use the open space beside the patrol route instead of crossing directly through the center.

3

Pause Between Routes

After each pickup, stop and watch the drone cycle again. A short pause is safer than attempting two movements during an uncertain opening.

4

Reach the Final Marker

Follow the remaining safe lane to the last marker. Once all five are collected, the ice wall is destroyed and the hidden entrance becomes available.

The marker sequence opens the route to the hideout. Inside, Murphy falls into a dangerous area, so the next priority is building a bridge. Move the curtain to find the hammer, collect the nearby beams, and use the hammer to remove the needed planks.

ItemWhere to LookUse
HammerBehind or near the curtainPull signs and secure bridge pieces
BeamsNear the interior doorwayForm the bridge foundation
PlanksAround the hideout and exterior areaCreate the crossing
Fallen signOutside the hideoutReveals an additional clue
SpikesFound during the searchServe as nails for the bridge

Place the beams and planks across the gap, then use the spikes as nails. The hammer completes the construction and allows Kate to cross safely to Murphy. Murphy then provides a gold ring and points toward the carved mantelpiece.

Do Not Skip the Exterior Search

Before returning inside, inspect the fallen sign and remove the other signs with the hammer. The clue beneath them is required for the later ring puzzle.

Hideout Puzzles and Key Items

The hidden base contains several linked puzzles. The ring mechanism is the main progression gate, but the surrounding objects also provide the tools needed to reach the final confrontation. Search both levels of the hideout instead of focusing only on the central puzzle.

Begin by collecting the ring from the fireplace and the skylight rod from above the mantelpiece. Use the rod to retrieve another ring, then place all three rings into the carved mechanism.

The rings must be rotated to match the letter pattern found outside. When the arrangement is correct, the framed number 7427 appears. Keep this number available because it is used later in the hideout sequence.

Puzzle or ObjectRequired ActionResult
Fireplace ringTake the ring from insideAdds one piece to the mantel mechanism
Skylight rodUse it to reach the high areaRetrieves another ring
MantelpiecePlace and rotate three ringsReveals the 7427 clue
Hidden ladderEnter through the fireplace routeLeads to the lower hideout
Globe-like objectOpen it with the chisel and hammerProvides syrup and a broken bottle
GeneratorPour in the syrupDistracts Colt

After entering the lower area, inspect the globe-shaped object. The chisel and hammer open it, revealing syrup and a broken bottle. Pour the syrup into the generator to create a distraction. This gives Kate an opportunity to take the fight manual and taser from Colt’s backpack.

Use the taser on Colt, then take the handcuff key from him. The key frees Caspia, Dan’s daughter, and moves the story toward the bridge confrontation with Sticks.

Clue Management

Keep the gate code 991224 and mantel number 7427 separate. They belong to different puzzles.

Item Management

The hammer is used for the bridge, exterior signs, and globe-like container. Recheck it before leaving an area.

Progression Check

The fight manual and taser should be collected before attempting to free Caspia.

Progress Check

You are ready for the final encounter when Murphy is safe, the lower hideout is accessible, Colt has been subdued, and Caspia’s handcuff key is in your inventory.

Final Bridge Fight Strategy

The final fight takes place after Sticks threatens Caspia. Step onto the bridge when you are prepared, then use the fight manual to identify the correct counter for each attack. The encounter lasts three rounds, with three move selections in each round.

The fight is based on matchup rules rather than damage statistics. Selecting a move without checking the manual can waste a round, so pause on the manual screen and compare the opponent’s action with the available counters.

Fight ElementWhat to DoWhy It Matters
Opponent actionIdentify the displayed moveEach move has a specific counter
Fight manualCheck the matchup relationshipPrevents weak or losing responses
Round structureChoose three moves per roundA full sequence is required
Defensive actionUse it when the manual recommends itSome attacks punish the wrong defense
Final roundFollow the counter chain carefullyWinning all rounds completes the case

The available actions include punches, kicks, elbows, dodges, blocks, and other special responses. The source walkthrough material indicates that the fight requires a sequence of evasive and countering moves rather than one repeated attack. In particular, the manual should guide choices involving dodge, block, and elbow responses.

Use this practical method:

  • Check the opponent’s move before selecting your response.
  • Match the move against the manual’s counter relationship.
  • Avoid repeating the same action unless the manual supports it.
  • Treat the first two rounds as pattern recognition.
  • Confirm the final round’s counter before committing.

If a selection fails, do not assume the entire chapter must be replayed. Reopen the fight instructions, compare the move relationships, and apply the correct counter in the next sequence. The ending follows once the three-round encounter is completed.

Chapter 4 Completion Checklist:

  • Collect the vodka from the snowy entrance
  • Enter the gate code 991224
  • Gather all five drone markers
  • Build the bridge and rescue Murphy
  • Align the rings and record 7427
  • Use the generator distraction and obtain the fight manual
  • Free Caspia and win the three-round bridge fight

A useful reference for the Chapter 4 item order is the On Thin Ice Chapter 4 walkthrough guide, published December 14, 2022. Use it alongside the in-game clues rather than skipping the puzzle logic.

Fight Reminder

The manual is the reliable source for the final matchup rules. Read the opponent’s move first, then select the listed counter instead of relying on a memorized attack pattern.

Chapter 4 FAQ

Q: What is the gate code in the On Thin Ice fight walkthrough?

The gate code is 991224. It comes from the three bullet-hole clues: one hole gives 99, two holes give 12, and three holes give 24.

Q: How many markers must Kate collect in the drone puzzle?

Kate must collect five markers. Watch the patrol routes, move during safe openings, and pause after each pickup to confirm the next route.

Q: What number is revealed by the ring puzzle?

The correctly aligned rings reveal 7427. First collect all three rings, then rotate them to match the letter pattern found outside the hideout.

Q: How do I win the final fight?

Read the fight manual and counter each opponent move across three rounds. The encounter uses matchup rules involving attacks, dodges, blocks, and counterattacks, so choose responses based on the displayed move.

The most common mistake in Chapter 4 is entering a code before collecting every clue. The gate and ring puzzles both use short number sequences, but they appear in different locations and solve different mechanisms. Another frequent error is treating the drone area as a race. Waiting for a patrol opening is usually safer than making a fast, uncertain move.

Final Tip

Keep a short note of 991224, 7427, and the fight-manual relationships. These are the key memory checks in Chapter 4.
