How to Get Research Badges in Last Z: Survival Shooter

Claims of a hidden duplication glitch or secret menu exploit for research badges in Last Z: Survival Shooter are false. Item rewards, drop calculations, and inventory tallies are verified on central servers, making client-side manipulation impossible. Attempting desync tricks or third-party exploits risks an account ban and wastes stamina and diamonds. Steady badge progression requires hitting high-tier event milestone chests, clearing daily radar tasks, and exchanging secondary shop currencies.

Maximizing Event Milestone Chests

The largest badge payouts come from cross-server Alliance Duel (State vs. State) milestones and daily Arms Race phases. Instead of spending development resources as soon as you get them, hoard them for aligned event days.

Max out Zone Commemoration: Invest in the Zone Commemoration research tree before expanding combat branches. This tree unlocks bonus chests and increases point multipliers across recurring events, permanently boosting your weekly badge yield.
Target Tier-9 Alliance Duel chests: Save speedups, training materials, and recruitment tickets until the active Alliance Duel day matches that specific action. Pushing points only on matching days ensures you hit all nine reward tiers.
Align point bursts with Arms Race: Time your Alliance Duel expenditures to overlap with matching hourly Arms Race requirements. Scoring points during overlapping phases unlocks rewards from both tracks simultaneously, giving you the best badge payout for your resources.

Buying Badges from Secondary Shops

Do not buy full-price badges with diamonds in the general store. Instead, convert recurring tokens earned through alliance activity, seasonal events, and competitive play.

Store	Currency Used	Priority	Usage Strategy
Alliance Shop	Alliance Honor Coins	High	Donate to alliance technology daily to sustain weekly token income.
Event Exchange	Seasonal Event Tokens	High	Purchase limited-quantity badge bundles before spending tokens on basic speedups or raw resources.
VIP Shop	Diamonds / VIP Points	Moderate	Buy badges here only when unlocked VIP levels provide discounted bundles.
Arena Store	PvP Tokens	Moderate	Balance badge purchases against any required hero fragments for your main lineup.

Daily Radar and PvE Farming

Open-world zombie farming yields vital crafting resources, but direct badge drops face sharp daily diminishing returns after your initial stamina pool is spent. Use your daily energy where badge returns remain predictable:

Clear radar stations twice daily: Clear the radar station every 8 to 12 hours so the mission queue does not cap out. Elite threat exterminations and rescue missions offer guaranteed Courage Badges and commander experience.
Complete daily activity points: Hitting your daily activity chest milestones provides a small, steady intake of badges alongside standard radar clears.
Target PvE double-drop windows: Reserve your diamond-purchased stamina refills for limited-time double-drop events rather than standard daily world-map farming.

Strategic Research Spending Rules

Advanced nodes in high-tier combat trees like Troop Tier 10 require tens of thousands of badges. Misspending early badges creates severe progression bottlenecks.

Prioritize chest-boosting tech: Complete the entire Zone Commemoration tree before investing heavily into standard combat defense and attack nodes.
Focus on a single troop branch: Choose your troop specialty (Shooter, Vehicle, or Warrior) based on your strongest hero lineup. Push that single branch toward its major tier thresholds before distributing badges into secondary troop trees.
Keep an emergency badge reserve: Maintain a reserve of several thousand badges. Server updates and seasonal transitions often introduce catch-up trees that provide more combat power per badge than older baseline branches.
