Last Z: Survival Shooter T10 Troops F2P Unlock Guide

To unlock T10 troops as a free-to-play (F2P) player in Last Z: Survival Shooter, focus your daily routine on maximizing research speed-ups, participating in event rewards, and funneling base resources directly into prerequisite technology nodes. Because late-game technology requires millions of resources and lengthy completion times, saving speed-ups exclusively for high-tier research projects is the single most important factor in reaching T10 status.

Managing Research Queues and Speed-Ups

The final research nodes leading to T10 troops present massive time bottlenecks. Your primary goal is to ensure your Research Center never sits idle while protecting your items for the longest build times.

Hoard Advanced Speed-Ups: Avoid spending universal or research speed-ups on short, mid-tier upgrades that finish in a few days. Save these items for the final, multi-week prerequisite research nodes.
Maintain Continuous Queue Action: If main prerequisite nodes are blocked by resource deficits, temporarily shift to secondary tech, such as resource gathering speed or construction efficiency, to keep the queue running.
Maximize Daily Events: Complete all daily quests and targeted events that offer research speed-ups as clear rewards.

Resource Gathering and Alliance Support

Resource scarcity frequently halts progression toward T10 tech. F2P players must balance daily gathering with active alliance contributions to sustain high-tier demands.

Category	Recommended Focus	Key Action
Base Output	Balanced production of food, wood, and steel	Upgrade resource structures alongside headquarters requirements
Alliance Market	Item acquisition via alliance store	Purchase resource packs using accumulated alliance points
Defense	Shielding gathered assets	Keep active troop defense to prevent losing stockpiled resources

Balancing Base Defense During the Grind

Focusing entirely on research can leave your account vulnerable during server events such as State vs. State (SvS). You must maintain combat readiness without diverting excessive resources away from your main tech goal.

Train Current-Tier Troops: Continue training your highest available troop tier to maintain base defense and fulfill daily activity points.
Avoid Over-Investing in Mid-Tier Units: Build enough troops to protect your base, but reserve your largest resource surpluses for the Research Center rather than massive army expansion.
Prepare for Gear Upgrades: As you approach the final T10 research nodes, begin saving equipment enhancement materials so your new units can deploy with adequate combat stats.
