Revealing the Concealed Switch and Sculpture Shard

Begin by inspecting the decorative potted plant resting along the left wall. Tap the plant to shove it aside, revealing an emergency maintenance switch mounted flush against the baseboard. Interacting with the switch causes the heavy modern hanging sculpture overhead to snap loose, crashing down into pieces on the tile floor. Tap the debris to collect a sharp sculpture shard, which acts as an improvised crowbar.

Interrogating Lobby Bot for the Security Code

Next, interact directly with Lobby Bot. To extract the security box code, select each of the four available dialogue queries. Pay close attention to the vocal dialogue and text formatting: three specific lines contain capitalized positioning words:

  1. "FIRST" corresponds to the security symbol displayed during the initial prompt.
  2. "CENTRAL" indicates the icon designated for the middle dial.
  3. "LAST" identifies the final symbol on the right dial.
Clue Dialogue OrderExtracted PositionTarget Icon Description
First InquiryPosition 1 (Left)Crescent Moon / Curving Arc
Third InquiryPosition 2 (Center)Intersecting Triangle Grid
Fourth InquiryPosition 3 (Right)Diamond with Center Dot

Navigate to the locked wall-mounted box beneath the digital directory. Adjust each tumbler to match the three retrieved symbols. When the box opens, retrieve the spool of copper wire.


Repairing and Reprogramming the Security Drone

With Lobby Bot momentarily malfunctioning, your objective shifts toward overloading and subsequently reprogramming its core memory boards. If you consult an official resource like the Haiku Games Official Portal for community hints, you will notice this sequence challenges spatial reasoning.

      ├──> Climb Ladder ──> Collect Flash Capacitor
      │
      └──> Connect Capacitor + Switch to Wire ──> Trigger Surge ──> Harvest Chips

Assembling the Surge Rig

  1. Tap Lobby Bot and wrap the copper wire securely around its exposed chassis.
  2. Slide the decorative plant on the far wall aside to expose a sealed service panel.
  3. Use the sculpture shard from your inventory to pop the stuck latch.
  4. Reach inside the cabinet to retrieve a ladder and a toolbox, then extract the screwdriver.
  5. Position the ladder directly beneath the modern ceiling fixture. Climb up and detach the high-output flash capacitor.
  6. Use your screwdriver on the wall light switch adjacent to the doorway to remove the switch mechanism.
  7. Return to the wired Lobby Bot. Place the flash capacitor and switch assembly onto the exposed copper wire leads, then flip the switch.

The sudden electrical surge completely fries the bot's defensive subroutines and pops open its motherboard tray. Collect the scattered computer chips.

Solving the Motherboard Reprogramming Puzzle

Insert the computer chips back into Lobby Bot's access panel to trigger the circuit mini-game. The puzzle board consists of an interlocking grid where every adjacent chip edge must match colors, pin traces, and connector types.

Chip Type / PositionPrimary Orientation RulesMatching Adjacent Edges
Top-Left Corner ChipDual-pin gold connectors pointing right and downMust link with the center-top bus
Top-Center ChipTriple-lead blue circuit traces running horizontallyBalances power between left and right gates
Center Hub ChipQuad-sided omni-connectorInterlocks all four surrounding microprocessors
Bottom-Left ChipGrounded copper grounding plate facing downwardLocks in the primary power feed
Bottom-Right ChipDual-lead green output pin directed upwardCompletes the return loop to the chassis

Rotate and slide each chip into position until all traces light up green. Once the diagnostic confirms successful reprogramming, Lobby Bot unlocks the executive elevator, granting you access to Sara Stikowski's office floor. In this phase of our on thin ice walkthrough chapter 2, proper chip alignment is crucial to avoid resetting the board.


Sara Stikowski Interrogation and Office Ambush

Upon entering the penthouse office suite, Kate and Penny catch Sara Stikowski—known street-negotiator "Sticks"—red-handed. Rather than pulling weapons immediately, Kate must engage in a tense psychological dialogue battle to gain Sticks' confidence before attempting an arrest.

[Confrontation]
      │
      ├──> "We never get a reward." (Dialogue 1)
      │
      ├──> "I have Hacksaw's evidence." (Dialogue 2)
      │
      ├──> Place Hard Drive on Desk
      │
      └──> (think about dinner) (Dialogue 3) ──> Sticks Deploys Smoke Bomb!

Dialogue Choice Walkthrough

Selecting incorrect dialogue options prompts Sticks to become defensive, resetting the conversation branch. Choose the exact conversational sequence outlined below to proceed smoothly:

  • Prompt 1: When Sticks challenges your motivations for entering her office, select:
    "We never get a reward."
    Reasoning: Playing into perceived departmental greed lowers her guard and makes Kate appear corruptible.
  • Prompt 2: When asked what bargaining leverage you bring to the table, select:
    "I have Hacksaw's evidence."
    Reasoning: This hooks her interest immediately, tying her directly to the precinct cyber-heist.
  • Item Action: Open your inventory, select Hacksaw's Hard Drive, and place it firmly upon her glass conference table.
  • Prompt 3: When Sticks leans in and tests your composure, choose:
    (think about dinner)
    Reasoning: Staying emotionally detached prevents Kate from giving away Penny’s tactical ambush positioning.

Before Penny can snap the handcuffs onto her wrists, Sticks triggers an emergency smoke bomb from her desk sleeve and vanishes into the vents, leaving the office blanketed in suffocating tear gas.


Clearing the Room and Gathering Clues

With visibility near zero, Kate Gray must act quickly to vent the office before crucial physical evidence is compromised.

      ├──> Move Rolling Chair ──> Grab Fan ──> Plug Into Floor Outlet
      │
      └──> Clear Gas ──> Collect 6 Room Items ──> Open Safe & Free Plaque

Venting the Toxic Smoke

  1. Tap the ergonomic rolling chair on the right side of the desk and push it away from the wall.
  2. Pick up the disconnected electric fan resting against the baseboard.
  3. Place the fan beside the floor outlet, plug it in, and switch it to high speed. The circulating air clears the toxic smog instantly.

Inventory Sweeping

Once the air clears, search every corner of the office thoroughly. Pick up the following items:

  • The doll sitting on the low credenza.
  • The decorative bookcase ornaments resting near the display shelves.
  • The durable curtain rope tied around the heavy window drapes.
  • The roll of duct tape near the corner workstation.
  • The desk lamp with frayed wiring.

Notice that Penny takes custody of the hard drive for secure evidence logging. Use your duct tape on the frayed wiring of the desk lamp to fix the short circuit, enabling you to inspect dark corners of the room. Next, select the curtain rope and target the brass key glinting from the high crystal chandelier. Tug the rope to pull down the chandelier key.


Unlocking the Safe and Bookshelf Ornament Puzzle

The final major puzzle in this chapter centers around Sara Stikowski's locked wall safe and her customized ornamental display shelves. Solving this multi-stage riddle requires careful inspection of hidden Polaroid photos.

                                                Arrange Shelves Based on Photos

Safe Cracking and the Polaroid Clues

Insert the chandelier key into the keyhole concealed behind the modern abstract painting. Turn the key to swing open the wall safe. Inside, collect the packet of Polaroid photos.

Open your inventory and examine the Polaroids under close inspection. Tap the photos to spread them across the viewing screen:

  1. Tap the small metal clamp resting inside the photo envelope to add it to your inventory.
  2. Note the visual details in each photograph: they depict a young, frightened girl holding specific items across distinct rooms and time periods.
  3. Take your clamp and tap beneath the bottom trim of the massive wooden bookcase. Use the clamp jaws to extract a jammed metal award plaque.

Arranging the Bookshelf Display

Now that you possess all four categories of decorative items—the doll, the fixed lamp, the award plaque, and the assorted bookcase ornaments—tap the large shelving unit. Place all collected items into the empty shelving bays.

To determine the correct placement of every item, correlate the height, tier, and adjacent objects depicted in the background of the Polaroids.

Shelf LevelLeft Column ItemCenter Column ItemRight Column Item
Top TierDecorative Wooden CarvingAntique Desk Lamp (Fixed)Bound Journal Stack
Middle TierPorcelain Child DollCommemorative PlaqueGeometric Glass Orb
Bottom TierSilver TrophyFramed Family PortraitCarved Soapstone Figurine

Aligning every ornament according to this exact layout triggers an internal mechanical latch. The entire bookcase slides back on hidden floor rails, exposing Stikowski's hidden escape elevator shaft.


Chapter 2 Escape and Final Sequence

As Kate and Penny realize Sticks has fled via the emergency roof chute, an alarm blares throughout the building. Returning to the main lobby, you find Lobby Bot crushed and spark-throwing under fallen ceiling debris, pleading for assistance.

[Secret Shaft Opened] ──> Return to Lobby ──> Rescue Lobby Bot ──> Chapter Complete

Tap Lobby Bot to lift the damaged unit clear of the rubble. Rescuing the bot concludes the corporate infiltration segment, preserving its black-box memory drive to track down Sticks' hideout in Chapter 3.


Pro Strategies and Common Chapter 2 Pitfalls

Completing this portion of the game without wasting stars requires careful navigation. Community reports and player experiences highlight several recurring trouble spots throughout Chapter 2:

  • The Second Plant Interaction: Many players get stuck after dropping the hanging sculpture. Remember that the plant on the right side of the lobby must also be shifted to reveal the concealed electrical maintenance panel.
  • Wiring Order Nuance: If you tap the flash capacitor before attaching the copper wire to Lobby Bot, the game will prevent placement. The wire must act as the circuit baseline first.
  • Photo Spread Interaction: Do not simply glance at the top Polaroid. You must physically tap and drag the photos to spread them across the screen; otherwise, the mechanical clamp remains hidden underneath the photo pile.
  • Final Drone Pickup: After the bookcase opens, you cannot leave the lobby without tapping the distressed Lobby Bot. This step is a required story trigger.

Frequently Asked Questions

Why can't I place the flash capacitor on Lobby Bot?

You must first wrap the copper wire around the robot's body. The copper wire creates the circuit path needed for the flash capacitor and wall switch to overload Lobby Bot's defensive system.

How do I find the clamp under the photos in this on thin ice walkthrough chapter 2 guide?

Open the Polaroid photos in your inventory and tap them to spread them apart. The clamp is hidden underneath the top photo layers and will only highlight once the stack is fully dispersed.

What are the correct dialogue choices when interrogating Sticks?

To prevent Sticks from fleeing early, select:

  1. "We never get a reward."
  2. "I have Hacksaw's evidence."
  3. Place Hacksaw's Hard Drive on the table.
  4. (think about dinner)
    Following this specific sequence unlocks the next puzzle segment.

What should I do if the bookshelf items won't lock into place?

Ensure you have collected all required items, including the award plaque stuck under the bookcase trim. The plaque must be retrieved using the mechanical clamp found inside the Polaroid envelope before the shelving puzzle can be completed.
