- Yet Another Zombie Survivors decide their fate achievement centers on clearing the opening wave extremely quickly.
- Green Hell is the most commonly recommended setting for creating faster explosive chain reactions.
- Engineer, Pyro, and Tank are the strongest reported character choices for this challenge.
- Exploding enemies can defeat nearby zombies and remove multiple targets at once.
- Restarting runs is normal because distant spawns can ruin an otherwise strong attempt.
Yet Another Zombie Survivors Decide Their Fate Achievement Requirements
The Decide Their Fate achievement is a speed-clear challenge tied to the first wave. Community attempts consistently focus on finishing that wave in less than 20 seconds, with successful examples reported at 19.46 seconds and 14.06 seconds.
The achievement is difficult because the result depends on more than raw damage. Enemy positioning, the first group you reach, your character’s attack pattern, and whether explosive enemies appear close enough to one another can all affect the final time.
The most reliable approach is to build a situation where one kill helps create several more. Instead of chasing every zombie individually, gather a dense pack and target enemies that explode when defeated. Their area damage can clear nearby targets and shorten the wave dramatically.
| Challenge Element | Practical Goal | Why It Matters |
|---|---|---|
| Wave timing | Finish the first wave under 20 seconds | The achievement is built around rapid wave completion |
| Map choice | Use Green Hell | Several successful attempts used this setting |
| Enemy grouping | Create a dense pack | Explosions become more valuable when targets stand together |
| Character choice | Try Engineer, Pyro, or Tank | These characters were repeatedly associated with successful attempts |
| Run quality | Restart unfavorable openings | Distant enemies can consume too much time |
A strong build can still miss the achievement when one or two zombies spawn far from the main group. Treat unfavorable enemy placement as a failed attempt rather than wasting the entire run.
Best Character and Setting Combinations
Three character approaches stand out for this achievement: Engineer, Pyro, and Tank. Ghost is also worth testing if you prefer an aggressive close-range strategy, but the available reports are less consistent than the recommendations for the other three choices.
Engineer is a strong first option because multiple players reported clearing the opening wave with this character. One reported result reached 14.06 seconds on Green Hell, although the same attempt still required several retries because enemies sometimes spawned too far away.
Pyro works well when the opening group is positioned for chain explosions. The important idea is not simply to burn down the nearest target. Instead, use your movement and attack direction to keep explosive enemies close to the rest of the pack.
Tank offers a more forgiving route for players who have trouble surviving while gathering zombies. A successful method involves moving toward a large group, allowing enemies to stack, and then using sustained fire and explosions to finish the wave.
Engineer
- Strong reported clear times
- Good choice for repeated attempts
- Watch for isolated enemies
Pyro
- Excellent with explosive clusters
- Pairs well with Green Hell
- Requires confident positioning
Tank
- Durable close-range approach
- Can gather large groups safely
- Benefits from circular movement
| Character | Recommended Style | Main Strength | Main Risk |
|---|---|---|---|
| Engineer | Direct wave clear | Reported sub-20-second results | Stray enemies may remain alive |
| Pyro | Explosion-focused pressure | Strong chain-reaction potential | Poor spacing reduces damage |
| Tank | Grouping and sustained fire | Easier enemy gathering | Takes time if the pack stays scattered |
| Ghost | Point-blank aggression | Fast access to dense groups | Requires precise movement |
Begin with Engineer on Green Hell if you want the clearest route to a fast time. Switch to Tank when survival or enemy grouping is the main problem.
Step-by-Step Decide Their Fate Achievement Walkthrough
Select Green Hell
Start the attempt on Green Hell. This setting is the most frequently associated with successful clears in the available strategy reports. Do not spend time trying to rescue an opening where the first enemies are widely separated.
Choose a Suitable Character
Pick Engineer for a damage-focused attempt, Pyro for explosion chaining, or Tank for a more durable grouping strategy. Ghost can also work if you are comfortable moving directly into point-blank range.
Move Toward a Dense Horde
Do not remain stationary near the starting position. Move toward a large group, with Tank players commonly heading straight downward or “south” until they reach a heavier cluster. The goal is to reduce the distance between targets.
Prioritize Exploding Enemies
Focus on larger enemies that explode when defeated. Their blast can damage or eliminate nearby zombies, allowing one kill to contribute to several eliminations. Keep the group compact while attacking.
Check the Timer and Restart Quickly
Watch the first-wave timer and aim below 20 seconds. If enemies spawn on the opposite side of the map or remain outside your attack range, restart and try again instead of forcing a slow run.
The key movement pattern is controlled circling. Let zombies gather toward a central point, then pass around the group while continuing to attack. This creates a compact target area and gives explosive enemies more opportunities to damage their own allies.
Avoid rushing directly after every isolated zombie. A short detour toward a dense group can be faster than chasing one target across the map. The challenge rewards efficient target density more than random movement speed.
| Phase | Action | Timing Focus |
|---|---|---|
| Opening | Move immediately toward the nearest dense group | Avoid idle seconds |
| Gathering | Circle or reposition to stack enemies | Keep targets within blast range |
| Damage | Attack explosive enemies first when possible | Trigger chain damage early |
| Cleanup | Eliminate survivors without crossing the map | Preserve the sub-20-second pace |
| Reset | Restart after a poor spawn pattern | Avoid slow attempts |
The winning pattern is usually simple: reach a dense horde, trigger explosive damage, and avoid long chases. Clean movement is often more valuable than a complicated build adjustment.
Movement, Explosions, and Common Mistakes
The explosive enemy mechanic is the central tactical detail for this achievement. When one of these zombies dies, its explosion damages nearby enemies. The effect is most useful when several targets are packed together, so your movement should support clustering rather than scattering.
A common mistake is assuming that Green Hell itself contains a special stage explosion. The explosion comes from certain zombies, not from a map-wide event. Once that distinction is clear, you can deliberately guide enemies into a formation where their deaths help clear the wave.
Another mistake is attacking immediately without shaping the group. Tank players can often improve their result by moving away briefly, allowing zombies to stack, and then running in a circle while firing. This approach gives the weapon and explosions more targets at once.
| Mistake | What Happens | Better Response |
|---|---|---|
| Chasing every zombie | The timer disappears during travel | Move toward the largest cluster |
| Ignoring explosive enemies | Damage remains mostly single-target | Prioritize large explosive targets |
| Standing still | Enemies may spread around you | Use circles to maintain a compact pack |
| Assuming every run is viable | Bad spawns create unavoidable delays | Restart quickly after a poor opening |
| Over-focusing on damage upgrades | Positioning remains inefficient | Improve target density before changing builds |
Use the following decision rules during attempts:
- If the largest group is nearby, move into its range and begin circling.
- If an explosive enemy is surrounded, prioritize it over a distant normal zombie.
- If several targets split into opposite directions, do not chase both.
- If the first wave is already moving beyond the target time, restart.
- If Tank feels too slow, test Engineer or Pyro rather than forcing the same route.
The available reports include successful times from several attempts, but they also describe repeated failures caused by enemies spawning far away. That makes a retry-based strategy more practical than expecting every run to produce the same opening.
The useful explosion comes from certain zombies when they die. It is not a separate Green Hell stage mechanic, so position enemies around the explosive target before finishing it.
Achievement Preparation Checklist and Reference
Use this checklist before starting a serious attempt. It is designed to keep the run focused on the conditions that matter most: speed, grouping, and explosive damage.
Before-Run Checklist:
- Select Green Hell as the challenge setting
- Choose Engineer, Pyro, or Tank
- Plan to move toward a dense enemy group
- Identify explosive enemies before committing to a target
- Restart quickly when distant spawns make the timer unrealistic
The community discussion used for this guide is available through the Steam discussion about the Decide Their Fate achievement. It includes reported character choices, Green Hell routes, explosion explanations, and example first-wave times.
| Reported Approach | Result or Observation | Use Case |
|---|---|---|
| Engineer on Green Hell | A reported 14.06-second first wave | Best starting point for damage-focused attempts |
| Pyro on Green Hell | A reported 19.46-second first wave | Useful for explosion-centered runs |
| Tank on Green Hell | Successful after repeated retries | Good for controlled grouping and durability |
| Ghost at point-blank range | Reported as a viable aggressive option | Alternative for confident close-range players |
These values should be treated as community-reported examples rather than guaranteed performance targets. Your opening spawn pattern may differ, and the same character can produce very different results depending on enemy spacing.
For most players, the practical progression is:
- Test Engineer for several attempts.
- Learn how explosive enemies affect nearby targets.
- Move to Tank if survivability or grouping is limiting progress.
- Use Pyro when you can consistently keep enemies packed together.
- Record your best time and adjust movement before changing characters again.
When your best attempt is close to the target, change your route before changing everything else. A tighter opening path can save more time than a different character.
Decide Their Fate Achievement FAQ
Q: What is the fastest reported route for the Decide Their Fate achievement?
The strongest reported examples use Green Hell with Engineer, Pyro, or Tank. One Engineer attempt reached 14.06 seconds, while another Pyro attempt reached 19.46 seconds during the first wave.
Q: Is Green Hell required for the achievement?
The available strategy reports strongly favor Green Hell, but they do not establish that it is formally required. It is recommended because several successful attempts used that setting.
Q: Which character should I use first?
Engineer is the best first test for players seeking a fast clear. Tank is a strong alternative when you need more room to gather enemies, while Pyro is useful for explosion-focused attempts.
Q: Why do I keep missing the sub-20-second target?
The most common issue is enemy placement. One or two zombies may spawn far from the main group, forcing a long chase. Restart those attempts and focus on runs with a dense opening horde.
For the best chance, use Green Hell, choose a reported strong character, gather a dense horde, trigger explosive kills, and restart poor spawn patterns quickly.
