Last Z Field Research Guide：Unlocking Conditions & Cost Breakdown

Greetings, Survivors! Welcome to our comprehensive guide on Field Research—one of the most crucial progression elements in Last Z: Survival Shooter.

From the structure of the research tree and exact buff values to the precise badge costs required for every level, we’ve compiled the definitive data so you won’t ever look back and say, "I wish I knew this beforehand..."

How to Unlock Field Research

If you can't find "Field Research" in your Research Center, it's not a bug! To unlock this tree, you must meet four specific prerequisite conditions.

Required Prerequisite Research:

• New Home: 100% Completed
• Elite Troops: 100% Completed
• Military Strategies: Reached 40% completion (This unlocks "Siege to Seize")
• Siege to Seize: 100% Completed

Only after finishing all of these will the "Field Research" tree finally appear in your lab.

 

Field Research Buffs

Field Research is a highly powerful tree designed to boost the firepower, durability, and training speed of your troops. It consists of 14 total categories.

Stat Boost Overview:

Category	Research Name	Max Effect (Fully Upgraded)
Global Buffs	Field Training / Camouflage Coating	Field Troop Attack & Defense +20%
Troop Attack	Mobility Enhancement / Close Combat / Weapon Modification	Specific Troop (e.g., Rider) Attack +20%
Training Speed	Training Speed UP (3 Types)	Specific Troop Training Speed +10% (Max Lv. 5)
Troop Defense	Armor Enhancement / Shield Modification / Tactical Cover	Specific Troop Defense +20%
Late-Game Buffs	Field Training II / Camouflage Coating II	Field Troop Attack & Defense +40% (Max Lv. 20)
Final Node	Charge Shield	All Troop HP +10%

The final node, Charge Shield (HP +10%), is the absolute most important stat here, as it directly impacts your overall survival rate in combat.

 

Required Costs & Developer's Trap

Based on our independently compiled Excel data, we have calculated the exact total number of Badges required to 100% complete this tree.

Cost Progression Analysis:

Completing the first 11 categories requires roughly 183,000 Badges. While your progression may feel smooth at this stage, this is exactly where a massive trap for beginners is hidden.

Phase	Required Badges	Notes
First 11 Categories (Total)	182,930	Smooth progression phase
Final 3 Categories (Total)	411,500	Costs spike massively
100% Completion (Total)	594,430	Confirmed total cost

Conclusion: The Final 3 Categories are the "Real Game"

When you look at the data graph, it becomes glaringly obvious—the final three categories alone account for nearly 70% of the entire tree's cost.

The game’s design plays on the psychological feeling of "I'm almost done," only to demand an astronomical number of Badges at the very end. If you start this tree without a solid plan, your resources will dry up instantly.

 

Strategy Tips

Once you achieve 100% completion in Field Research, three brand-new specialized research trees will unlock: Shooter Training, Assaulter Training, and Rider Training. These allow you to further specialize the stats of each troop type.

Final Advice for Commanders:

• Mandatory for T10 Troop Users: While the badge cost is enormous, the buffs provided are game-changing. If you plan on running high-tier (T10) troops, you cannot avoid this grind.
• Stockpiling Badges is Priority #1: Keep the massive number of 594,430 Badges in your mind, and plan your resource gathering accordingly.
