decaying winter true ending: What It Is
The decaying winter true ending is commonly used to describe the Oblivion ending, an alternate conclusion connected to the cultist takeover event. It is unlocked through a hidden sequence delivered in Morse code by a broken drone in the Mountain area.
Unlike a standard evacuation, this route adds a special extraction, a separate Oblivion area, five Nightmare waves, and a final battle against Zealot Void. The ending is completed only after the final boss is defeated.
| Stage | Main objective | Result |
|---|---|---|
| Hidden setup | Complete the five required tasks | Oblivion route becomes available |
| Night 10 | Finish the normal progression | Special extraction begins |
| Oblivion | Survive five Nightmare waves | Final boss encounter unlocks |
| Boss wave | Defeat Corrupted Zealot Void | Oblivion ending completed |
Hidden Route
Follow the Morse-code instructions instead of treating the broken drone as scenery.
Inventory Check
Select equipment before extraction because only carried inventory is preserved.
Nightmare Trial
Expect escalating cultist, shadow, High Priest, and boss encounters.
Treat the Orange Knife and the three shadow kills as separate objectives. Finishing one does not replace the others.
Step-by-Step Oblivion Unlock
Use the following order to complete the hidden route efficiently. The map contains several objectives, so clear them before Night 10 whenever possible.
Break the Lamp Posts
Destroy every lamp post around the map. Missing even one lamp can prevent the hidden sequence from progressing, so sweep the outer routes and central areas before moving on.
Find the Orange Knife
Enter the castle walls and obtain the Orange Knife. Defeating SQ first is recommended because it can make this pickup safer and easier to reach.
Kill the Three Shadows
Eliminate the shadows located in the Gallery, above the map near the castle, and by the Mines. The castle and Mines targets require firearms, so reserve ammunition for them.
Open the Lab and Speak With Zym
Take the knife and keycard to open the Lab, then visit the High Priest room. Speak with Zym repeatedly until his dialogue advances. This adds five minutes to the timer.
| Objective | Area | Practical note |
|---|---|---|
| Lamp posts | Around the map | Sweep methodically; do not assume the visible central lamps are enough |
| Orange Knife | Inside the castle walls | Defeat SQ first if the route is contested |
| Shadow one | Gallery | Check the Gallery before leaving the area |
| Shadow two | Near the castle | Use a gun for this elevated target |
| Shadow three | Mines | Keep ammunition ready before entering |
| Zym | High Priest room | Repeat the interaction until the dialogue continues |
Do not enter Night 10 assuming the route is active. Verify the lamps, knife, shadows, Lab access, and Zym dialogue first.
Extraction Preparation and Oblivion
After the steps are complete and Agents finish Night 10, a 30-second preparation period begins. Use this time to load only the items that matter for the next encounter.
The extraction area does not preserve every resource container interaction. Rations, ammunition, and scraps stored inside an Agent container may not transfer when the container is equipped. The infection meter resets to zero after entering the new area, so infection medicine is less important for this section.
Recommended carry priorities include:
- I4S-DS
- Tactical Armor
- Medkits
- Tourniquets
- Reliable firearms and ammunition
- Speed-enhancing supplies for the final boss
| Carry priority | Examples | Why it matters |
|---|---|---|
| Protection | Tactical Armor | Helps reduce incoming damage during preparation and waves |
| Healing | Medkits, Tourniquets | Supports recovery across repeated encounters |
| Survival tools | I4S-DS | Useful for maintaining combat readiness |
| Mobility | Speed stims | Important when avoiding Zealot Void attacks |
| Low priority | Rations inside containers | May not transfer through the extraction |
Pack for the Nightmare sequence, not for extended scavenging. Vital combat supplies are more valuable than uncertain container contents.
Once extraction is complete, the player enters Oblivion after a cutscene. Reikgon announces the special wave, and the team receives a short preparation window before enemies begin converging from the sides of the map.
Nightmare Waves and Boss Order
The Nightmare event contains five waves. Each wave increases pressure through additional cultists, shadows, major threats, and a designated boss. After Wave 5, the team receives a brief break before Corrupted Zealot Void appears.
| Wave | Major threats | Boss |
|---|---|---|
| 1 | Akimbo Cultists, Skinners | Enraged Sickler |
| 2 | Monkey Wrench, Pipe Wrench, Akimbo Cultists, Skinners | High Priest |
| 3 | SPAS Cultists, Hangers, prior enemies | Battlejuice High Priest |
| 4 | Gunner Cultists, Hangers, SPAS Cultists | Lebrock High Priest |
| 5 | Cultists, shadows, frequent Skinners | Celldweller |
| Final | Corrupted enemies and summoned threats | Corrupted Zealot Void |
The special High Priests require different responses:
Battlejuice
Uses dual Tec-9 guns, dodges, rolls, and slides. It has lower health than the other special High Priests but is difficult to pin down.
Lebrock
Uses Hollow’s Scythe and a dangerous spin attack. It has high health and gains speed during its attack pattern.
Celldweller
Throws daggers, releases close-range barrages, and summons groups of Lost Souls. The summoned enemies have very low health but high speed.
All High Priests can use Shadowfade. When a dark aura surrounds one, shove it to interrupt the ability. If the effect completes, the enemy can heal back to full health.
Focus on positioning and target priority. Clear fast-moving nuisances before they surround the team, then coordinate damage on the wave boss.
Corrupted Zealot Void, Checklist, and FAQ
After the Nightmare waves, Reikgon summons a chained, undead Zealot Void through a red portal. The boss wields two Deo Volentes and has 15,001 HP. The encounter has a three-minute limit.
Its light attack deals 25 damage, while the heavy attack can deal 100 or 150 damage depending on the situation. The spin and dash attacks are lethal, so avoid them rather than trying to absorb the hit. Zealot Void cannot be shoved, and parrying is a core survival tool.
The boss becomes faster as its armor deteriorates. A practical team arrangement is to assign one player to maintain parries while other players attack from safer angles. Speed stims can help with emergency repositioning, but they do not replace clean timing.
