Decoding Last Z's Field Research Branch

Field Research in Last Z: Survival Shooter is a crucial, high-investment research branch that significantly enhances combat capabilities. It's not an early-game objective but rather a substantial commitment for players progressing into late-game optimization.

Field Research at a Glance

This branch represents a significant badge investment, culminating in powerful enhancements. Here's a quick overview of its key characteristics:

• Total Cost: 600,190 badges to fully complete.
• Prerequisite: Requires 100% completion of the Siege to Seize branch.
• Final Reward: The ultimate node, Recharge Shield, is unlocked after a substantial badge expenditure.

It's important to note that the cost distribution is heavily skewed towards the end. The final three nodes alone account for 414,610 badges, making the latter stages particularly demanding.

Field Research in the Overall Progression

Field Research is positioned as a significant late-game combat research path. It becomes available only after completing 100% of the Siege to Seize branch. This places it well after foundational research lines like Hero Training, Military Strategies, and Peace Shield.

Completing Field Research acts as a gateway to more specialized training, unlocking subsequent branches dedicated to specific troop types: Shooter Training, Assaulter Training, and Rider Training.

Key Research Milestones

Understanding the badge expenditure at different stages of Field Research can help in planning your progression:

• Initial Nodes: The first two nodes, Field Training I and Camo Coating I, combine for a relatively modest 20,760 badges, which can be deceptive regarding the branch's overall cost.
• First Combat Spread: After finishing the three middle Lv. 1-10 nodes (Mobility, Melee, Weapon Upgrading), you will have spent 67,380 badges, moving past the initial affordable stages.
• Before the Final Wall: The first 11 nodes accumulate to 185,580 badges. This means the remaining two Lv. 1-20 nodes and Recharge Shield demand an additional 414,610 badges.
• Reaching Recharge Shield: The final node, Recharge Shield, is unlocked after a total expenditure of 600,190 badges. Its power is substantial, but it requires enduring the two expensive Lv. 1-20 nodes preceding it.

What Follows Field Research?

Field Research is a pivotal transition point. It's the bridge to highly specialized late-game military enhancements. Due to its cost and unlock requirements, most players prioritize other badge-efficient branches first.

Upon completing Field Research, you will unlock:

• Shooter Training
• Assaulter Training
• Rider Training

Each of these troop-specific branches is a massive undertaking, costing 1,440,070 badges individually, beyond the Field Research investment.

Quick Tips

• Late-Game Focus: Treat Field Research as a significant late-game commitment, not an early or mid-game detour.
• Prerequisite: Ensure Siege to Seize is 100% complete before planning to tackle Field Research.
• Cost Awareness: Be prepared for the disproportionate badge cost concentrated in the final three nodes.
• Strategic Unlock: Completing this branch opens up critical troop-specific training, essential for specialized armies.
• In-Game Verification: Always confirm current node costs and unlock conditions within the game's research screen before committing resources.
