rex infernus Cube Step Locations
The rex infernus cube step takes place in the Vaitharian Sanctuary and uses four movable symbols: Fire, Hand, Leaf, and Water. Before interacting with the puzzle wall, locate all four cubes and identify their symbols. The safest approach is to activate Death Perception, which makes nearby interactable objects easier to spot during a busy Zombies round.
Video Highlights:
- Find the Fire cube and carry it to the empty slot in the Sanctuary wall.
- Insert the symbols in the required Fire, Hand, Leaf, Water order.
- Keep Leaf and Water away from Fire while moving symbols across the wall.
- Use the Hand symbol as the movable buffer during the orb sequence.
The available location references use nearby landmarks rather than a numbered map coordinate system. The exact approach can feel different depending on where you enter the room, so confirm each cube by its symbol before carrying it to the wall.
| Cube | Symbol | Landmark to check | Search priority |
|---|---|---|---|
| 1 | Fire | Pillar or shelf near the Gobblegum machine | First |
| 2 | Hand | Nearby shelf, often close to Mule Kick | Second |
| 3 | Leaf | Above a window or on the floor near the puzzle wall | Third |
| 4 | Water | Window ledge or wall area near the room entrance | Fourth |
The symbols are more reliable than the landmarks. If a shelf appears empty, scan the nearby floor and ledges because a cube can roll or despawn temporarily during the round. Death Perception remains useful when the room is crowded with effects, enemies, and interactable props.
Fire
The opening symbol. Place it first and keep it away from Leaf and Water during later swaps.
Hand
The control symbol. It acts as the buffer that allows the other cubes to move safely.
Leaf
The third opening-wall symbol. It must not touch Fire while the puzzle is being rearranged.
Water
The final opening-wall symbol. Keep it separated from Fire during the orb sequence.
Pick up one cube at a time and return it directly to the wall. This reduces the chance of losing track of a symbol during a hectic round.
Loading the Wall in the Correct Order
Once the cubes are gathered, approach the empty wall slots in the Vaitharian Sanctuary. The first input is straightforward, but the order matters. Insert the four cubes from the bottom or starting position according to the following sequence.
| Input number | Symbol | Required action | Confirmation |
|---|---|---|---|
| 1 | Fire | Place the Fire cube into the first empty slot | The cube locks into the wall |
| 2 | Hand | Place Hand into the next slot | The central circle begins responding |
| 3 | Leaf | Add Leaf after Hand | The symbol remains accepted |
| 4 | Water | Add Water last | The full set activates |
The correct order is Fire, Hand, Leaf, Water. The important restriction is not merely the insertion order. Leaf and Water must also avoid contact with Fire during the second phase. If either forbidden pairing touches while the symbols are transferred, the arrangement can reset.
Place Fire First
Carry the Fire cube to the wall and insert it into the first slot. Do not move it again until the wall activates and the orb phase begins.
Add the Hand Cube
Insert Hand next. The central circle should light up or respond, confirming that the wall has recognized the opening pair.
Insert Leaf Without Contact
Place Leaf in the third slot. Keep it separated from Fire while positioning the cube, because the puzzle can reset when the restricted symbols touch.
Finish With Water
Add Water to the final slot. When all four symbols are accepted, the wall transitions to the orb-driven arrangement phase.
If the wall does not activate, inspect the slots rather than immediately abandoning the attempt. A cube may have been placed into the wrong holder, or a symbol may have been dropped before it fully registered. Check the visual symbol on every cube and reinsert the sequence carefully.
Do not test random arrangements. Fire must begin the sequence, Hand follows it, Leaf comes third, and Water closes the initial setup.
Orb Driver Swap Sequence
After the four cubes are accepted, the wall divides into left and right holders and a yellow orb appears in the center. Shooting or activating the orb transfers the current symbol arrangement from one side to the other. This is the puzzle’s main logic check.
The Hand cube is essential because it provides the movement buffer. Fire cannot touch Water, and Fire cannot touch Leaf. Instead of trying to move every symbol directly, use Hand to separate the restricted pairings before each transfer.
| Phase | Key holder state | Orb action | Main restriction |
|---|---|---|---|
| 1 | Fire on the right, Hand on the left | Activate the orb | Establish the starting arrangement |
| 2 | Hand moved before Water | Activate the orb again | Water must not touch Fire |
| 3 | Fire returned after Water is moved | Activate the orb | Keep Fire away from Water |
| 4 | Leaf placed after Fire is moved | Activate the orb | Leaf must not touch Fire |
| 5 | Hand remains as the buffer | Final activation and placement | Preserve the separated arrangement |
Follow the swap pattern below rather than moving symbols based on appearance alone.
Start With Fire and Hand
Put Fire on the right side and Hand on the left side. Activate the orb to begin transferring the symbols across the wall.
Move Hand Before Water
Send Hand back first, then place Water into the open position. Activate the orb so Water can move without touching Fire.
Return Fire Safely
Move Water out of the restricted position before returning Fire. Use Hand as the buffer and activate the orb again.
Insert Leaf After Fire Moves
Remove or relocate Fire before placing Leaf. Leaf must not occupy a position where it touches Fire during the transfer.
Complete the Final Arrangement
Use Hand to separate the remaining symbols, send the arrangement across, and place Fire into the final accepted slot.
The sequence is easier to understand as a rule: Hand moves first whenever a restricted symbol must pass another symbol. Treat Hand as the empty-space tool in a sliding puzzle. The orb transfer is not a speed challenge, so pause after each activation and confirm where every symbol is located.
The puzzle is progressing correctly when the orb responds to each transfer and the symbols remain separated according to the Fire restrictions.
Failure Recovery and Reliable Setup
The Rex Infernus cube puzzle is designed to punish rushed swaps rather than slow execution. Zombies can pressure the room, and a dropped cube may become difficult to see, but most failed attempts can be recovered without restarting the entire match.
Use the following troubleshooting table when the wall does not respond or a cube seems to be missing.
| Problem | Likely cause | Recommended fix |
|---|---|---|
| Wall rejects the opening set | Wrong symbol order | Remove the cubes and repeat Fire, Hand, Leaf, Water |
| Cube is not visible | It rolled, despawned, or is hidden by effects | Activate Death Perception and scan shelves, ledges, and floor areas |
| Orb transfer fails | A restricted pair touched | Rebuild the arrangement using Hand as the buffer |
| Symbols appear out of order | A transfer was activated too early | Pause after each orb interaction and verify both holders |
| Attempt is lost | The puzzle reset during the round | Wait for the next round and search the original landmarks |
If you are playing with a squad, assign one player to carry cubes and another to control nearby enemies. A third player can call out the current left and right holder positions. This reduces accidental pickups and makes it easier to follow the swap order.
Solo Method
Clear a safe path, carry one cube at a time, and pause after every orb activation to verify the arrangement.
Duo Method
One player transports cubes while the second player watches the wall and handles nearby enemies.
Squad Method
Assign a carrier, a defender, and a caller who tracks the left and right holder positions.
A failed attempt does not necessarily require a checkpoint reload. The available guide information indicates that the cubes can return to their fixed locations when the next round begins. Use that reset as a recovery window: regroup, reactivate Death Perception, and repeat the opening sequence instead of searching randomly.
Before Activating the Orb:
- Confirm Fire, Hand, Leaf, and Water are all identified
- Insert the opening sequence as Fire, Hand, Leaf, Water
- Check that the central wall response has activated
- Keep Hand available as the movement buffer
- Verify Fire never touches Leaf or Water during swaps
Have one player call out every orb activation. Clear communication prevents a second player from moving a cube before the current transfer finishes.
Completion, Reward, and Quick Reference
When the final arrangement is accepted, the sealed door opens and the Sanctuary route advances. The puzzle also provides access to a random perk according to the available guide information, making the step useful beyond simply opening a hidden passage.
The most important information is summarized below for quick reference during a match.
| Category | Correct answer |
|---|---|
| Map area | Vaitharian Sanctuary |
| Cube symbols | Fire, Hand, Leaf, Water |
| Opening order | Fire first, Hand second, Leaf third, Water last |
| Buffer symbol | Hand |
| Forbidden contact | Fire with Leaf or Water |
| Reset response | Wait for the next round and search the fixed locations |
| Completion result | Sealed door opens; a random perk may be awarded |
For the full visual route, use the Rex Infernus Cube Symbol Solver Guide as a companion reference. Keep the written sequence beside you, because the orb phase is easier to follow from the symbol rules than from repeated trial and error.
The short version is:
- Find all four cubes before starting the wall.
- Load Fire, Hand, Leaf, Water.
- Use Hand to create safe transfers.
- Never allow Fire to touch Leaf or Water.
- Activate the orb only after confirming the current holder positions.
- If the puzzle resets, wait for the next round and begin again.
Slow, deliberate transfers are safer than rapid inputs. The puzzle rewards correct spacing and symbol management, not fast movement.
Q: What is the correct rex infernus cube step order?
Insert the cubes into the Sanctuary wall in this order: Fire, Hand, Leaf, then Water. This is the required opening sequence before the orb transfers begin.
Q: Where can I find the four Rex Infernus cubes?
Search the Fire pillar or shelf near the Gobblegum machine, the Hand shelf near Mule Kick, the Leaf area above a window or near the puzzle wall, and the Water window ledge or nearby wall area. Use the symbol itself to confirm each cube.
Q: Why does the Rex Infernus cube puzzle keep resetting?
The most common reason is allowing Fire to touch Leaf or Water during the orb phase. Move Hand first and use it as a buffer before transferring a restricted symbol.
Q: What happens after the cube puzzle is completed?
The sealed Sanctuary door opens and the side objective advances. The guide information also identifies a random perk as a possible completion reward.
