Wondering how to save everyone in SubZero? To achieve the elusive "Golden Ending" where all three companions survive the frozen apocalypse, you must prioritize affinity-boosting dialogue, secure key survival items like Reina’s rations, and strategically hoard dice modifiers for the final Marina Bay escape. This comprehensive guide breaks down the exact dialogue paths and RNG manipulation needed to keep Wu Yi, Li Meng, Meng Kelan, and Reina alive until the credits roll.
The Core Mechanics: The Key to How to Save Everyone in SubZero
SubZero (冰点之下), the hit live-action interactive FMV game from Joy Media Limited, isn't your standard visual novel. When a sudden global freeze hits Marina Bay and zombie hordes emerge from the blizzard, your fate as warehouse clerk Wu Yi (Leo) is tied to a literal 20-sided die. The game has taken the Steam charts by storm since its release, largely because of how brutally it punishes reckless decisions.
The game operates on a dual-axis system: Affinity and Dice Modifiers. Every major dialogue decision you make impacts your relationship with the three female survivors. High affinity unlocks crucial backstory, hidden FMV cutscenes, and loyalty. But more importantly, it grants positive modifiers (e.g., +2 or +3) to your life-or-death dice rolls during action sequences. If your roll fails to meet the hidden difficulty class (DC) of an encounter, a character dies permanently, and the game autosaves, locking you into that tragic timeline.
To understand how to save everyone in SubZero, you have to stop playing it purely as a dating sim and start playing it as a tabletop strategy game. You cannot afford to spread your affinity evenly in the early game just to see different romantic cutscenes. You must hit specific relationship thresholds with Reina, Li Meng, and Meng Kelan at exact moments to earn the modifiers required to survive the late-game zombie sieges. The UI will often flash a subtle blue aura around choices that boost affinity, but it won't warn you when a choice secretly penalizes your dice pool.
The golden rule of the game is simple: Never take a risk without a modifier. The fateful die burns in your grip, and raw RNG will eventually betray you. By selecting the optimal dialogue paths, you essentially rig the dice in your favor, ensuring that when the blizzards blur morality, your bonds are strong enough to carry you through.
Step-by-Step Walkthrough: How to Save Everyone in SubZero
The journey through the frozen wasteland is split into four critical phases. Make the following choices to secure the maximum dice modifiers and keep the entire party breathing.
Chapter 1: The Marina Bay Warehouse & Reina
The game opens with Wu Yi enduring workplace oppression right before the cold snap hits. The FMV sequences here do an excellent job of establishing the suffocating atmosphere of the warehouse. When the temperature plummets and the dead begin to walk, your first encounter is with Reina, a cheerful pastry chef seeking shelter. Her bright demeanor is a stark contrast to the grim reality outside, but don't let her innocence fool you—she is vital to your long-term survival.
- Choice 1: The Rations. When Reina discovers your stash of canned goods, select "Share the warehouse rations equally." Do not hoard them. This grants an immediate +15% Affinity with Reina and unlocks the "Morale Boost" buff for the next two days.
- Choice 2: The Barricade. When the first zombie groans are heard outside, Reina will panic. Choose "Calm her down and reinforce the loading dock door together." This requires a baseline dice roll of 10. Because you shared the rations, Reina grants a +2 modifier. You only need to roll an 8 or higher.
- Choice 3: Pastry Shop Defense. Later in the chapter, you must venture to her ruined shop. When given the option to scavenge or run, choose "Trust her intuition about the back alley." This avoids a deadly ambush and secures a permanent +1 modifier to all evasion rolls for the rest of the game.
Chapter 2: The Archery Student Li Meng
As you push further into the icy wasteland, the cinematography shifts to blinding whites and deep shadows. You encounter Li Meng, a pragmatic archery student who is highly skeptical of your group's survival chances. Winning her over is the most difficult part of learning how to save everyone in SubZero, as her dialogue checks are notoriously unforgiving. She values action over words, and any attempt to placate her with empty promises will result in a sharp drop in affinity.
- Choice 1: The First Impression. When Li Meng draws her bow on you, do not raise your weapon. Select "Keep your hands visible and explain your destination." Raising your weapon results in a permanent -20% Affinity penalty, making her survival in Chapter 4 mathematically impossible.
- Choice 2: The Zombie Ambush. During the blizzard trek, a zombie will flank Li Meng. The game gives you a split-second QTE choice. Select "Cover her blind spot with the steel pipe." You will be forced to make a dice roll (DC 14). Use your saved evasion modifier from Reina here to guarantee success.
- Choice 3: Upgrading the Arsenal. At the abandoned sporting goods store, you find a composite bow. Give it to Li Meng immediately by selecting "Let her take the lead shot." This choice upgrades her combat effectiveness, turning her from a liability into your primary defense against the horde. She will now grant a +3 modifier to all ranged combat rolls.
Chapter 3: Meng Kelan’s Conspiracy
Meng Kelan is the wildcard of the group. Played with an icy reserve, she is elegant, mysterious, and clearly hiding something about the origins of the global freeze. Her storyline is heavily tied to the game's overarching conspiracy involving the military and the sudden drop in global temperatures. Earning her trust requires a delicate touch; you must be inquisitive but never accusatory.
- Choice 1: The Radio Signal. When you intercept a military broadcast, Kelan will try to turn it off. Choose "Question the radio signal gently." Do not interrogate her aggressively. This builds trust and reveals her tactical background.
- Choice 2: The Blizzard Shelter. When the temperature drops to absolute zero, you must find shelter. Kelan will suggest a risky path through a frozen subway tunnel. Select "Accept the tactical intel and follow her lead."
- Choice 3: The Revelation. When Kelan's secret is finally uncovered—that she knew about the outbreak before it happened—the group will fracture. You must choose "Protect her from the group's anger." This is the most crucial decision in the game. By defending her against Reina and Li Meng's accusations, you secure her absolute loyalty, granting you the "Tactical Genius" buff, which allows you to reroll one failed die in the final chapter.
The Final Stand: The Last Step in How to Save Everyone in SubZero
Chapter 4 is a relentless gauntlet that tests every decision you've made over the past three hours of gameplay. The harbor is swarming with the undead, the cold is lethal, and every step requires a dice roll. The tension in these final FMV sequences is palpable, with the soundtrack dropping away to nothing but the howling wind and the clatter of the physical die on the screen. If you have followed the guide up to this point, you should have Reina's evasion modifier, Li Meng's ranged combat modifier, and Kelan's reroll ability.
The Harbor Horde Sequence
The final escape to the extraction helicopter is broken down into three consecutive dice rolls. This is where most players fail and lose a survivor.
- The Breach (DC 15): The zombies break through the frozen barricade. The game will prompt you to run or fight. Choose "Hold the line at the docks." You will roll the die. Apply Kelan's +3 tactical modifier. If you roll low, use her reroll ability immediately.
- The Flank (DC 16): A fast-moving variant will attempt to drag Reina away. Choose "Call out to Li Meng." Because you upgraded her bow in Chapter 2, she will automatically cover the flank, bypassing the dice roll entirely and saving Reina's life.
- The Final Sprint (DC 18): The helicopter is in sight, but the ice is cracking beneath your feet. You must make one last agility roll. Apply Reina's evasion modifier and any remaining buffs. Because your affinity with all three women is maxed out, the game grants a hidden "Bonds Born of Crisis" bonus (+4 to the final roll).
When the die settles, the screen will fade to white. Instead of the mournful elegies of a bad ending, you will see Wu Yi, Li Meng, Meng Kelan, and Reina sitting in the back of the chopper, watching the frozen ruins of Marina Bay shrink in the distance. You have successfully navigated the conspiracy and kept the entire party alive.
FAQ: Answering How to Save Everyone in SubZero
Can you save Li Meng if you fail the Chapter 2 blind spot roll? No. If you fail the DC 14 roll to cover her blind spot, she sustains an injury that slows her down permanently. During the final sprint in Chapter 4, the injury will cause her to fall behind, and she will be lost to the horde regardless of your final dice roll.
Is it possible to survive without Meng Kelan's reroll ability? Technically yes, but it requires extreme luck. The final DC 18 roll is brutal. Without Kelan's reroll and the "Tactical Genius" modifier, you are entirely at the mercy of RNG. Defending her in Chapter 3 is the only reliable way to guarantee the Golden Ending.
What happens if I keep the rations for myself in Chapter 1? If you hoard the rations, Reina's affinity drops to zero, and she will not grant you the evasion modifier. Furthermore, she will likely panic and flee during the Chapter 2 pastry shop defense, resulting in her immediate death.
Does the PC version of SubZero have different dice mechanics than mobile? No, the core RNG and modifier mechanics are identical across Steam and mobile versions. The exact same dialogue paths and affinity thresholds apply to all platforms.
Mastering this interactive thriller requires patience, strategic foresight, and a willingness to put the group above yourself. By manipulating the affinity system and securing those crucial dice modifiers, you can defy the grim odds of the frozen apocalypse. The fateful die may burn in your grip, but with this path, you control the outcome.
