Last Z: Survival Shooter Radar Mission Stacking and 996 Cap Guide

In Last Z: Survival Shooter, radar mission stockpiling stops working once your station queue reaches 996 stored missions. If you hit this ceiling, the system halts all automatic mission generation, and any newly collected radar items or natural refreshes are permanently lost. To protect your daily progression, you should maintain a working inventory between 800 and 900 missions.

How the 996 Mission Cap Works

The radar station previously allowed unbounded mission accumulation, enabling players to stockpile tasks indefinitely for competitive events. Under the 996 hard cap, reaching the maximum total locks out all new incoming missions.

When your station sits at 996, the refresh timer continues running, but no tasks are added to your board. Any extra radar items activated while capped fail to register, resulting in a total loss of hero experience, speedups, stamina packs, and recruitment tickets.

Safe Stacking Thresholds

To safely stockpile tasks without triggering the overflow penalty, establish a personal ceiling between 850 and 900 missions:

• Keep a 100-mission buffer: Storing no more than 896 tasks leaves room for daily passive resets, sudden mail deliveries, and bulk alliance reward claims without breaching the 996 limit.
• Trigger a clear-out at 900: Whenever your counter reaches 900, run a clearing session to trim your total back down to the 700–800 range.
• Account for downtime: If you anticipate being offline across several station refresh cycles, lower your mission count further to ensure passive refreshes do not push you into the cap while away.

How to Clear Stored Missions Efficiently

When pruning your queue to stay under the limit, clear lower-value objectives first so that valuable rewards remain available for competitive scoring events.

1. Complete quick survivor rescues: Civilian rescues and pickup tasks finish immediately without requiring extended march times or heavy action point (AP) costs.
2. Burn low-stamina targets: Prioritize tasks with minimal stamina requirements if your immediate goal is creating space before the next refresh cycle.
3. Deploy multiple squads nearby: Assign marches to adjacent zombie targets near your shelter rather than sending squads across long map distances.
4. Reserve epic and legendary tasks: Keep your highest-rarity targets untouched until active scoring windows open, discarding or completing only common tasks to free up queue capacity.

Coordinating Mission Clearing with Events

Radar missions provide substantial points during server competitions such as Alliance Duel and Vs event stages. Coordinate your queue around the weekly event schedule to extract maximum value:

• Build the reserve before scoring days: Over the two to three days preceding a radar or stamina event, let your missions accumulate within the 800 to 900 safe range.
• Deplete the queue when scoring opens: As soon as the event phase begins, aggressively complete 400 to 500 stored missions. This clears major point milestones immediately while dropping your station count well below the risk zone.
• Cycle incoming tasks during the event: Once your backlog drops below 800, your station immediately resumes passive generation, providing extra tasks that you can complete for additional points before the scoring window closes.
