The Alliance Support Hub in Last War: Survival, formerly called the Alliance Center, determines how many alliance helps you can receive on eligible construction, research, and troop-healing timers. It starts at 5 helps at level 1, reaches 20 helps at level 30, and can reach 23 helps at level 35.
Each alliance help reduces the remaining timer by 0.5% or at least 1 minute, whichever gives the larger reduction. This makes the Hub increasingly valuable as building and research timers stretch from hours into days.
★Quick Take: Do not ignore the Alliance Support Hub. Besides increasing your help limit, it is a direct Headquarters prerequisite at several stages. You need Hub level 7 for HQ8, level 15 for HQ16, level 23 for HQ24, and level 33 for HQ34.
How Alliance Help Works in Last War
When you start an eligible building upgrade, technology research, or Hospital healing queue, you can request help from your alliance. Other members tap the Help button, and every successful response removes time from the task.
The official help rule is based on the remaining timer:
- Each help removes 0.5% of the remaining time; or
- At least 1 minute is removed if the percentage would be smaller.
Because 0.5% of 3 hours and 20 minutes equals one minute, tasks with more than roughly 3h 20m remaining benefit from the percentage calculation. Shorter tasks normally receive the one-minute minimum instead.
This also means help on a very long construction or research project can save considerably more than one minute per member. Since each percentage reduction is calculated from the remaining timer, requesting help as soon as the task begins gives your alliance the largest available timer to work with.
!Important: Upgrading the Alliance Support Hub primarily increases how many help responses the task can receive. It does not mean a level 30 Hub automatically makes each individual member’s help remove a larger percentage. Check your Headquarters Buff Stats for the help reduction currently applied to your account.
Last War Alliance Support Hub Levels 1–35
The table below lists the current Alliance Support Hub levels, resource requirements, and maximum Help Received count. This directly addresses one of the most important reasons to upgrade the building: more levels allow more alliance members to reduce the same timer.
Levels 31–35 belong to later Age of Oil progression and also require Oil. Construction times are not included below because the displayed duration can vary substantially with research, VIP, Builder’s Hut bonuses, Survivors, profession effects, and other construction-speed modifiers.

Best Alliance Support Hub Levels to Prioritize
You do not need to keep the Alliance Support Hub equal to your Headquarters at every stage. The most important targets are the levels that either add another help or satisfy an upcoming HQ prerequisite.
Hub Level 7 for HQ8
Upgrading Headquarters to level 8 requires the Alliance Support Hub at level 7. At that point, your maximum help count is 8.
Hub Level 15 for HQ16
HQ16 requires a level 15 Alliance Support Hub. Level 15 provides up to 12 helps, making alliance assistance more useful as mid-game construction and research timers become longer.
Hub Level 23 for HQ24
HQ24 requires the Support Hub at level 23. Level 23 raises the maximum to 16 helps.
Hub Level 30
Level 30 is not an immediate HQ30 prerequisite, but it provides a useful late-game benchmark with up to 20 helps. Whether you should rush it depends on your resources, builder availability, and how actively your alliance fills help requests.
Hub Level 33 for HQ34
Advanced Headquarters progression eventually requires the Alliance Support Hub again. To reach HQ34, the Hub must be level 33, where its help limit rises to 22.
✓Recommendation: Plan the Support Hub around your next HQ checkpoint rather than upgrading it randomly. If you are approaching HQ8, HQ16, HQ24, or HQ34, start the required Hub level early so it does not become an avoidable progression bottleneck.
Alliance Support Hub Levels 31–35 and Age of Oil
After Season 2, later progression introduces the Age of Oil technology tree. Completing the required HQ Expansion research opens the route beyond Headquarters level 30 and allows eligible buildings, including the Alliance Support Hub, to progress toward level 35.
Levels 31–35 add Oil to the direct upgrade cost. The help limit rises from 20 at level 30 to 23 at level 35:
- Level 31: 21 helps
- Level 32: 21 helps
- Level 33: 22 helps
- Level 34: 22 helps
- Level 35: 23 helps
Because these upgrades require substantial Food, Iron, Coins, and Oil, do not max the Hub simply because level 35 becomes available. Prioritize the levels needed for Headquarters progression and compare optional Hub upgrades against your Tech Center, military buildings, Barracks, Hospitals, and Age of Oil research.
For more context on the progression that leads into this stage, see the Last War Season 2: Polar Storm guide.
How to Get the Most From Alliance Help
Request Help Immediately
Send the help request as soon as construction, research, or healing begins. On long timers, 0.5% of the remaining time can be considerably more valuable than the one-minute minimum.
Join an Active Alliance
The Hub’s maximum help count is only useful if enough members actually respond. An active alliance that fills requests quickly can provide more real progression value than a higher-level Hub in an inactive group.
If your requests regularly remain far below the maximum help count for hours, changing your alliance situation may improve progression more than spending resources on another Hub upgrade.
Start Important Tasks During Active Hours
If possible, begin long construction, research, or healing tasks when your alliance is busy. Alliance Exercise, major events, reset periods, and other high-activity windows can make it easier to fill the help counter quickly.
Use the Help-All Button for Other Members
Alliance help works both ways. Make a habit of clearing available help requests when you log in. It costs no construction or research resources and supports faster progression across the alliance.
Use Alliance Help for Faster Healing
The one-minute minimum makes alliance help particularly useful for troop healing. Instead of starting one enormous Hospital queue after a battle, active alliances can use smaller healing batches and repeatedly request help.
For example, a level 30 Support Hub allows up to 20 helps. If alliance members respond quickly, a healing batch around 20 minutes can be cleared extremely quickly because each help provides at least one minute of progress.
You can then start another small healing batch, request help again, and repeat. This approach can return troops to action much faster during alliance events or sustained fighting than waiting on one large healing timer.
The method depends heavily on alliance activity. If members are offline or requests fill slowly, larger healing batches may be more practical.
Combine the Support Hub With Other Speed Bonuses
Alliance help is most effective as one layer of a broader development-speed strategy. Construction and research speed bonuses reduce the task duration, while alliance members reduce the remaining timer after the task begins.
Builder’s Hut
The Builder’s Hut supports construction efficiency through its building bonuses and assigned Survivors. The Last War Builder’s Hut guide explains how to get more value from that system.
Research and Alliance Technology
Development technologies can improve construction or research speed, while alliance technologies provide shared buffs to members. These bonuses compound in value over hundreds of upgrades rather than only affecting one task.
VIP Benefits
VIP levels can provide additional development benefits depending on the level and active privileges. Review the Last War VIP Levels and Perks guide before spending Diamonds or VIP Points solely for a particular bonus.
Construction and Research Speedups
Let alliance members deliver their helps before spending large amounts of speedups when practical. Free alliance assistance can reduce the timer first, allowing you to use fewer speedup items to finish the remaining duration.
Is the Alliance Support Hub Worth Upgrading?
Yes. Unlike many optional buildings, the Support Hub provides both an ongoing efficiency benefit and several mandatory Headquarters checkpoints.
Its value is highest when:
- You are in an active alliance that fills most help requests.
- You are approaching a mandatory HQ checkpoint.
- Construction and research timers have reached several days.
- You participate in PvP and frequently need fast troop healing.
- Your Hub is far below the progression level your account now needs.
Its optional upgrades become lower priority when your alliance rarely responds, your next HQ does not require the building, or the resources are urgently needed for a stronger military, research, or Headquarters upgrade.
F2P and Spender Upgrade Priorities
F2P and Low-Spending Players
Prioritize mandatory Support Hub levels and take advantage of every free help your alliance provides. Alliance assistance is especially valuable for F2P players because time saved through help is time you do not need to cover with purchased or earned speedups.
Between mandatory HQ checkpoints, compare another Hub level with the immediate value of your Tech Center, troop buildings, Hospitals, and main combat center.
Higher-Spending Players
Players with larger resource and speedup reserves can keep the Hub closer to their overall progression level. Additional help capacity still has value because high-level construction and research timers are long enough for percentage-based helps to remove meaningful amounts of time.
Players who would rather begin from a later stage of progression can optionally compare a Last War account for sale. Check the Headquarters level, research, heroes, troop tiers, buildings, server progression, and overall account development rather than judging an account by its Support Hub alone.
Common Alliance Support Hub Mistakes
- Forgetting the HQ checkpoints: Hub levels 7, 15, 23, and 33 can become direct blockers for later Headquarters upgrades.
- Assuming every help is only one minute: long timers receive 0.5% of the remaining time when that amount is greater than one minute.
- Waiting before requesting help: percentage-based help has more potential value while the remaining timer is still large.
- Staying in an inactive alliance: unused help capacity provides no timer reduction.
- Maxing the Hub ahead of core progression: optional levels should not consume resources needed for a more important HQ, research, or military upgrade.
- Using speedups before alliance help arrives: when there is no urgency, take the free reductions first.
- Healing one huge batch during active events: smaller batches can exploit the one-minute minimum and repeated alliance help more efficiently.
FAQs
How many helps can the Alliance Support Hub receive?
The maximum depends on its level. It starts at 5 helps at level 1, reaches 20 at level 30, and rises to 23 at level 35.
How much time does one alliance help remove in Last War?
Each help reduces 0.5% of the remaining timer or at least one minute, whichever provides the greater reduction. This applies to eligible construction, research, and troop-healing tasks.
What Alliance Support Hub levels are required for Headquarters upgrades?
Important checkpoints include Support Hub level 7 for HQ8, level 15 for HQ16, level 23 for HQ24, and level 33 for HQ34.
Is the Alliance Center the same as the Alliance Support Hub?
Yes. Alliance Center is the older name still used in some guides and interfaces. Current building references call it the Alliance Support Hub.
Should I max the Alliance Support Hub to level 35?
Not immediately. Level 35 provides 23 helps, but advanced upgrades consume large amounts of Food, Iron, Coins, and Oil. Complete mandatory HQ requirements first, then compare optional levels with your other Age of Oil priorities.
Can alliance help speed up troop healing?
Yes. Eligible Hospital healing queues can receive alliance help. Smaller healing batches are particularly effective in active alliances because every help provides at least one minute of progress.
Conclusion
The Alliance Support Hub is more than a minor support building. Its help capacity reduces construction, research, and healing timers throughout your account’s life, while specific Hub levels are mandatory for several Headquarters upgrades.
Plan around the level 7, 15, 23, and 33 HQ checkpoints, request help immediately, and stay in an alliance active enough to fill your available helps. For more building, research, alliance, hero, and progression strategies, browse the Heaven Guardian Last War: Survival guides.
