Unlock Endurance and Infinite in YAZS 1.0
Updated: Aug 21, 2026
Checked for version 1.0.0a on August 21, 2026. Older searches use “Endless,” but the current game separates long runs into two modes: Endurance and Infinite.
The three-step unlock sequence
The sequence is short, but two details cause most confusion: mode names changed before full release, and unlocks are stored per arena. Treat each arena as its own progression track.
1. Finish a Default run on the arena
Choose the arena where you want the longer modes and complete its Default run. That completion opens Endurance on that same arena. If Endurance is visible on another arena but missing on the one you selected, you have probably completed Default elsewhere rather than on the current map.
“Complete” matters here. Starting the run, reaching a particular build, or surviving for a while is not the same as finishing the arena’s Default objective. Use the run result and the mode selector as your confirmation. After the completion screen, return to the arena selection and check the same arena rather than switching maps immediately.
2. Reach 30:00 in Endurance
Select Endurance for that arena and survive until the timer reaches 30:00. The official Version 1.0 changelog names this exact condition for Infinite. You do not need to clear Hardcore to satisfy it.
The safest way to verify the trigger is to let the timer cross the 30-minute mark, finish or leave the run normally when practical, and then reopen the mode selector for the same arena. If you stop just before 30:00, the condition is not met. If you reach 30:00 on a different arena, the unlock applies there instead.
3. Select Infinite on that arena
Once the condition registers, Infinite becomes available beside the other modes for that arena. Infinite is the open-ended survival branch: it does not turn every map into Infinite at once, and it does not replace Endurance. Repeat the Default and 30-minute Endurance steps anywhere else you want to play Infinite.
This is the complete operational answer. Character choice, weapon choice, achievement completion, and a specific synergy may affect how comfortably you survive, but the supplied Version 1.0 sources do not make any one of them an additional unlock requirement.
Endurance vs Infinite
The two modes share the idea of surviving beyond a standard run, but they serve different points in progression.
| Mode | How it opens | What the run is for | What it unlocks |
|---|---|---|---|
| Default | Available through normal arena progression | Complete the arena’s standard run and learn its pressure pattern | Endurance on that arena |
| Endurance | Complete Default on the same arena | Face an escalating long-run challenge and prove the run can reach 30:00 | Infinite on that arena at 30:00 |
| Infinite | Reach 30:00 in Endurance on the same arena | Continue an open-ended run and test how far the squad can go | No global map unlock is claimed here |
Endurance is therefore both a playable challenge and the bridge to Infinite. Infinite is the limit-testing destination. Calling either one “Endless” can be convenient when searching, but using the current names in the menu prevents you from looking for a mode label that no longer exists.
Why is Infinite still locked?
Work through this checklist in order. It separates a missed requirement from an interface refresh or a version mismatch.
- Confirm the arena. The 30:00 run and the Infinite selection must be on the same arena. A successful Endurance run on one map does not unlock every map.
- Confirm the mode used for the timer. The official 1.0 condition is 30:00 in Endurance. Time spent in Default, Hardcore, Boss Rush, or another mode does not substitute for that named condition.
- Confirm the timer actually reached 30:00. A defeat at 29:59 is still short. If the result was close, run Endurance again and watch the timer pass the threshold.
- Return to the selector after the run. Leave the results flow and reopen the arena’s mode choices. The selector is the practical place to verify whether the state registered.
- Check the installed version. This guide is checked against 1.0.0a. Older Early Access builds, cached guides, and historical videos may describe a different route.
- Do not use Hardcore as the test. Version 1.0 says Infinite now correctly unlocks at 30 minutes in Endurance instead of by completing Hardcore. Clearing Hardcore is not the current Infinite condition.
Practical run preparation
The unlock requirement does not prescribe a build, so preparation should stay simple. Use a squad you already understand, prioritize staying alive over experimenting with several unfamiliar mechanics, and choose upgrades that solve the pressure you are actually seeing. The goal of this run is a reliable 30:00 Endurance result, not proof that one weapon or Survivor is universally best.
Keep movement space in mind and avoid treating the final seconds as already complete. When the run approaches 30 minutes, protect the attempt instead of making a risky change solely for extra damage. After the timer crosses the mark, note the arena before leaving; this prevents a later mix-up about which map should now show Infinite.
Because version 1.0 added content and a hotfix immediately after release, avoid assuming an old unlock video reflects the current menu. The historical video may still explain why players type “unlock Endless,” but the official 1.0 announcement is the authority for the present 30-minute Endurance condition.
Frequently asked questions
Where did Endless mode go?
The old Endless concept was split into Endurance and Infinite in version 0.9. Endurance is the escalating challenge branch; Infinite is the open-ended branch. In Version 1.0, search for those two names in the arena mode selector rather than a button labeled Endless.
Does Hardcore unlock Infinite?
No. The official Version 1.0 changelog says Infinite now correctly unlocks by reaching 30 minutes in Endurance for each arena instead of by completing Hardcore. Hardcore may be part of other progression, but it is not the condition documented for this unlock.
Does one 30-minute run unlock Infinite on every arena?
No. Infinite unlocks separately for each arena. Complete Default and then reach 30:00 in Endurance on every arena where you want the Infinite option.
How do I end an Infinite run?
Infinite is designed as the open-ended branch, so this guide does not invent a completion target. End the attempt through the normal run flow available in your current build when you are finished, and treat the result as a distance test rather than a standard arena clear.
