Efficient Research with Two Laboratories

To significantly accelerate your progress in Last Z: Survival Shooter, securing the Research License and establishing a second Laboratory early on is paramount. This dual research capability is among the most valuable enhancements available, allowing simultaneous development of multiple research branches alongside your primary progression.

When to Acquire the Second Research Facility

The second Laboratory becomes accessible once your Headquarters reaches Level 18 (HQ18) and requires a Research License for activation. We highly recommend purchasing this license promptly upon reaching the unlock criteria, prioritizing it over less impactful expenditures.

• Advance your Headquarters to Level 18.
• Continue developing your primary Laboratory for Headquarters advancements and critical research breakthroughs.
• Prioritize obtaining the Research License to activate the additional research queue.
• Allocate the secondary queue to advantageous, complementary research while your main path remains focused on core development.

Common Errors with Dual Research Queues

Avoid these pitfalls to maximize your research efficiency:

• Upgrading the incorrect facility: The initial Laboratory remains crucial as its progress is directly linked to Headquarters upgrades and fundamental research unlocks. Keep its development a high priority.
• Disregarding research significance: While a second facility boosts research speed, it does not validate inefficient or minor research choices. Strategic selection is still key.

Optimizing Both Research Paths

Effectively managing two research queues involves strategic division of labor:

• Distribute efforts: Keep the primary research line advancing through core progression, while the secondary queue focuses on developing beneficial ancillary branches.
• Understand badge requirements: An additional queue provides more research capacity; it does not reduce the badge cost associated with any specific research branch.
• Avoid excessive secondary upgrades: Maintain the utility of the second lab, but ensure its demands do not divert crucial resources away from your main progression objectives.

Quick Tips

• Get HQ18 Fast: Unlock the second lab as soon as possible.
• License First: Prioritize the Research License immediately.
• Main Lab Focus: Keep your primary lab on core HQ and major unlocks.
• Second Lab Side Projects: Use the second lab for useful, supplementary research.
• Don't Over-Invest: Allocate resources wisely; avoid over-upgrading the second lab.
• Strategic Choices: Ensure all research, main or secondary, is valuable.
