Last War: Survival – Unlock Unit X Guide & Costs

Unit X in Last War: Survival is an end-game troop tier unlocked through advanced Special Forces research. Reaching it requires a level 30 Barracks, a level 30 Tech Center, several prerequisite technologies, billions of Gold, and tens of thousands of Valor Badges.

Because Unit X requires such a large investment, players should plan the full research path before spending resources. This guide explains the listed requirements, costs, benefits, and the fastest practical route toward unlocking it.

What Is Unit X?

Unit X is presented as the troop tier above level 9 units. It represents a major late-game military milestone for players who have completed the required buildings and advanced research.

The supplied article states that Unit X provides approximately:

• 20% higher core statistics than level 9 troops
• 10% higher Troop Load
• Improved overall troop power
• Stronger hero-related troop attributes

These percentages should be checked against the current troop comparison screen because troop values may change through updates, research bonuses, decorations, and other account effects.

Unit X Listed Statistics

The supplied article lists the following Unit X values:

Statistic	Listed Value
Power	1,647
Morale	600
Troop Load	2,200
Hero HP	2,514
Hero Attack	204
Hero Defense	204

Important: Verify whether these are base troop values or statistics affected by research, buildings, heroes, and other account bonuses.

Unit X Unlock Requirements

The supplied requirements are:

• Level 30 Barracks
• Level 30 Tech Center
• Advanced Protection research
• HP Boost III research
• Attack Boost III research
• Defense Boost III research
• Unit X research

The Barracks and Tech Center must therefore be developed before the final troop research becomes available.

Read the Last War Barracks guide for troop-building progression and the Last War Tech Center guide for research requirements.

Unit X Research Path

The Unit X route appears to follow the Special Forces research tree.

The listed sequence is:

1. Advanced Protection
2. HP Boost III
3. Attack Boost III
4. Defense Boost III
5. Unit X

Some technologies may contain several internal levels or require additional prerequisite nodes. Check the complete research tree before assuming these five names represent every required upgrade.

Unit X Gold and Valor Badge Costs

Research Requirement	Gold	Valor Badges
Advanced Protection	1.72B	16,960
HP Boost III	2.77B	19,040
Attack Boost III	2.77B	19,040
Defense Boost III	2.77B	19,040
Unit X	560M	2,400
Listed Total	10.59B	76,480

The supplied rows add up to approximately 10.59 billion Gold and exactly 76,480 Valor Badges.

This total may exclude:

• Earlier prerequisite technologies
• Tech Center upgrade costs
• Barracks upgrade costs
• Research speed-ups
• Food, iron, or other resources
• Troop training costs after Unit X is unlocked

Use the table as a research estimate rather than the complete account cost.

Why Valor Badges Are the Main Bottleneck

Gold can be produced, collected, purchased, and opened from resource chests. Valor Badges are usually more restricted because they come from selected competitive events, stores, and offers.

The supplied path requires 76,480 Valor Badges, making them one of the most important resources to save.

Possible Valor Badge sources include:

• Alliance VS
• Warzone VS
• Special events
• Glittering Market offers
• Research packs

Read the Last War Valor Badge guide for farming and spending priorities.

Should You Rush Special Forces Research?

Focusing only on the shortest path toward Unit X can reduce the time needed to unlock the troop tier. However, skipping useful side technologies may leave your account unbalanced.

A direct rush may be appropriate when:

• Your level 30 buildings are already complete.
• You have enough Valor Badges for the full path.
• Your main squad is well developed.
• You compete actively in PvP and alliance events.
• Unit X provides more value than other research options.

A slower approach may be better when:

• Your troop statistics are weak despite high troop tiers.
• Your hospitals or training buildings are underdeveloped.
• You lack Gold and research speed-ups.
• Your heroes, gear, or drone are the real bottleneck.
• Side research offers stronger immediate value.

Best Research Priority for Unlocking Unit X

A practical order is:

1. Confirm every prerequisite in the Special Forces tree.
2. Finish the level 30 Tech Center requirement.
3. Finish the level 30 Barracks requirement.
4. Save enough Valor Badges for the next full research milestone.
5. Complete Advanced Protection.
6. Complete HP Boost III.
7. Complete Attack Boost III.
8. Complete Defense Boost III.
9. Finish Unit X research.

Avoid starting several expensive branches at once if Unit X is your main objective.

How to Farm Enough Gold

The listed research path requires more than 10 billion Gold. This amount usually takes long-term planning.

Possible Gold sources include:

• Resource production
• Gold mines and world-map gathering
• Resource choice chests
• Alliance rewards
• Daily activities
• Campaign rewards
• Events
• Paid resource packs

Keep resource chests unopened until the Gold is needed. This preserves flexibility and may reduce the amount of exposed resources in your base.

How to Reduce Unit X Research Time

Use Research Survivors

Assign survivors who improve research speed or Tech Center performance before starting a long upgrade.

Request Alliance Help

Alliance assistance can reduce research time, although it does not replace Gold or Valor Badge requirements.

The Last War Alliance Support Hub guide explains how alliance assistance supports long upgrades.

Use Research Speed-Ups

Save research-specific speed-ups for the longest Special Forces technologies.

Activate Research Bonuses

Check for VIP benefits, survivor bonuses, positions, decorations, and temporary buffs that may reduce research time.

Research During Events

Starting or completing expensive research during an event may provide additional milestone points and rewards.

How Long Does Unit X Take to Unlock?

The original article states that Unit X can take several days, but this is likely too general for a complete end-game research path.

The actual time depends on:

• Your current research progress
• Tech Center level
• Barracks level
• Available Valor Badges
• Gold supply
• Research-speed bonuses
• Speed-up inventory
• Alliance help
• Paid progression

For accounts starting far from the listed requirements, the complete process may take much longer than several days. Players already near the final node may finish much faster.

Is Unit X Worth Unlocking?

Unit X is generally worthwhile for late-game players who participate in competitive combat and already have the required infrastructure.

It can provide value through:

• Higher troop statistics
• Improved march power
• Better PvP performance
• Stronger alliance-event participation
• Higher carrying capacity
• Improved performance in difficult combat content

However, troop tier alone does not guarantee victory. Unit X performs best when supported by:

• Strong heroes
• High star levels
• Developed gear
• Advanced drone progression
• Relevant research
• Proper squad composition

Should You Upgrade Every Barracks?

If the game allows multiple Barracks, check whether all of them need to reach level 30 or whether one qualifying building unlocks the required troop progression.

Additional Barracks upgrades may still improve:

• Training capacity
• Training speed
• Parallel troop production
• Promotion efficiency
• Overall troop readiness

Do not assume every Barracks must be maxed before starting Unit X research unless the current requirement screen confirms it.

Training Unit X After Unlocking It

Completing the research only unlocks the troop tier. You must still train new Unit X troops or promote existing lower-tier units where the game allows it.

Prepare for:

• Large Gold and resource costs
• Long training times
• Training speed-up use
• Barracks capacity limits
• Hospital capacity requirements
• Higher recovery costs after battle

Unlocking Unit X without enough resources to train them may provide limited immediate combat value.

Should You Promote Level 9 Troops or Train New Unit X?

The best choice depends on the current promotion and training costs.

Promoting existing troops may be useful when:

• You already have a large level 9 army.
• Promotion is faster than fresh training.
• An event rewards troop promotion.
• The resource cost is efficient.

Training new Unit X may be useful when:

• Your existing army is small.
• You need to maintain lower-tier troops for other purposes.
• Fresh training provides better event points.
• Your Barracks can train large batches efficiently.

Compare the current resource, time, and event-point values before deciding.

Common Unit X Mistakes

Saving Only Gold

Valor Badges are often the more restrictive requirement. Plan both resources together.

Ignoring Building Costs

The listed research total does not include the full cost of reaching level 30 Barracks and Tech Center.

Researching Unrelated Branches

Spreading Valor Badges across several advanced trees can delay Unit X significantly.

Using Speed-Ups Outside Events

Expensive research may provide more value when completed during a research or power event.

Unlocking Unit X Without Training Resources

The troop tier provides no immediate army increase until troops are trained or promoted.

Neglecting Heroes and Gear

Higher-tier troops cannot fully compensate for weak heroes, skills, equipment, or drone development.

Assuming the 20% Increase Is Universal

The exact difference may depend on the statistic and account bonuses. Verify the current troop comparison.

Expecting the Unlock to Take Only Several Days

The full path can take much longer when buildings, prerequisites, badges, or Gold are still missing.
