Formation power is the number that gets checked before every rally, the metric alliances use to evaluate members, and often the deciding factor in whether you win or lose a competitive fight in Last Z Survival. When your formation power stalls, it usually has nothing to do with troop count. It comes down to how faction bonuses, hero synergy, equipment, vehicles, and research interact.
This guide covers the highest-impact ways to increase formation power in Last Z: Survival Shooter, from faction stacking and the best formation setups to Hall of Honor, vehicle upgrades, and research priority.
If you spend $500+/month on Last Z, here is how to use this guide:
- The faction stacking section explains why concentrating your investment into one faction produces more formation power than spreading across multiple.
- The vehicle and Hall of Honor sections cover power sources most players undervalue. These are where invested accounts pull ahead of accounts with similar spending but worse sequencing.
- The research priority section shows why HP research is the highest-return investment for raw formation power, not attack or defense.
Best Formation Strategy in Last Z: Survival Shooter
The strongest formations in Last Z are not built around individual hero power. They are built around faction synergy. When you deploy five heroes from the same faction, you unlock hidden buffs to attack, defense, and troop stats that outweigh what any single off-faction hero contributes.
This means the best formation setup for most accounts is a full faction lineup, even if some of those heroes are lower rarity. The raw power gain from faction stacking consistently outperforms mixed lineups where one strong hero from another faction breaks the synergy bonus.
Focus Investment on One Faction First
Concentrated investment into a single faction compounds formation power faster than spreading resources. Upgrades, gear, and skill books all amplify the same faction bonus when applied to the same lineup. For accounts with monthly budgets, this focus means every dollar invested hits harder because it compounds on one synergy instead of being diluted across many.
Equipment and Skill Upgrades
Hero equipment that boosts core stats (attack, defense, HP, troop damage) has the highest impact on formation power. Damage-boosting and HP-heavy gear generally outperform small stat bumps elsewhere. Skills should follow the same logic: prioritize combat performance upgrades over economic perks until your main formation is stable.
Modified Vehicles: Hercules and Beyond
Vehicles in Last Z provide direct stat buffs and unique skills that affect your entire formation. The Hercules is the first meaningful vehicle upgrade and is accessible at moderate progression levels. Higher-tier vehicles like the Destroyer require heavier investment but deliver formation-wide power increases that scale with the rest of your squad. Vehicle upgrades are one of the most undervalued formation power sources at higher account levels.
How to Increase Troop Size in Last Z
Unlocking higher troop tiers (T9, T10) produces the biggest raw power jumps in the game. Each tier significantly increases attack, defense, and HP stats across your formation. Match your troop types with your chosen faction's strengths. If you run Blood Rose heroes, prioritize Assaulters first. Training the right troops at the highest available tier matters more than simply training more troops at lower tiers.
Hall of Honor: Permanent Power from Maxed Heroes
Once heroes reach certain milestones, they can be placed in the Hall of Honor. This provides permanent stat boosts that apply across your entire roster, not just the heroes in your active lineup. Even heroes you no longer use in battle contribute extra troop capacity, attack, and defense through the Hall. This is where long-term investment into heroes continues to pay off even after they leave your main formation.
Research Priority for Formation Power: HP First
Research trees in Last Z run deep, and it is easy to waste badges on low-impact nodes. For raw formation power, troop HP research provides the highest return. HP upgrades scale harder and push formation power higher for the same investment compared to attack or defense research. Start by maxing Alliance Recognition for more badges, then move into Elite Troops and HP-heavy research branches.
Attack and defense research still matter for actual combat performance, but HP is the most efficient path if your primary goal is increasing visible formation power. When the strategy is mapped out and the sequencing is clear, the remaining variable is execution consistency. Formation power climbs fastest when upgrades land during the right event cycles and investment stays on schedule across weeks and months.
For players managing significant monthly budgets, the friction usually sits between intent and execution: delayed purchases, payment issues during event windows, or time spent managing transactions instead of coordinating with your alliance.
Last Z Survival Shooter: Formation Power FAQs
What is the best formation in Last Z: Survival Shooter?
The strongest formation is a full five-hero lineup from a single faction. Faction bonuses provide hidden attack, defense, and troop stat buffs that outweigh individual hero power from mixed lineups.
How do you increase troop size in Last Z?
Unlock higher troop tiers through barracks and HQ progression. Each tier provides significant stat jumps across attack, defense, and HP. Match troop types to your faction's strengths for maximum formation power.
What does the Hall of Honor do in Last Z?
The Hall of Honor provides permanent stat boosts that apply across your entire roster. Maxed heroes placed in the Hall contribute troop capacity, attack, and defense to every lineup, even if they are no longer in active combat use.
Is HP research the best priority for formation power?
For increasing visible formation power, yes. Troop HP research scales harder than attack or defense research for the same badge investment. Max Alliance Recognition first for badge supply, then focus on HP-heavy branches.
Should I invest in Hercules or save for Destroyer?
Get Hercules as soon as possible. It provides meaningful formation power at accessible progression levels. Destroyer is worth pursuing for accounts with higher monthly investment, but Hercules should not be skipped while waiting.
Your alliance's combined budget can produce more power...
Here is the multiplier most alliance leaders miss.
If your top 15 members each spend $1,000/month, your alliance is investing $15,000+ per cycle into Last Z. That is serious infrastructure. The question is whether that $15,000 produces maximum collective formation power, or whether platform fees, bad timing, and individual purchasing inefficiency eat into what actually reaches your accounts.
Most players buy through the App Store or Google Play at full retail. For a single player, the overhead is annoying but manageable. For an alliance where 15+ members are all paying that overhead independently, it compounds into a meaningful amount of lost efficiency across a season.
Packsify routes purchases through official channels in a more efficient way than buying solo. Same packs, same in-game delivery, same official payment rails. The difference is at the system level: your alliance's combined monthly investment produces more actual in-game power without anyone changing how or where they play.
For alliance leaders, this is not about individual optimization. It is about giving your entire alliance a structural edge. When every member's budget produces more resources, more hero copies, and more formation power, the alliance compounds that advantage across every competitive cycle.
This is not a coupon system or a grey-market shortcut. It is infrastructure built for players and alliances who treat their game investment as a long-term asset.

For Alliance Leaders Managing Alliance-Scale Investment
If you are already spending $1,000+/month and lead (or co-lead) an alliance, Whale+ gives you verified status on the Play Smarter Community Discord and access to a VIP channel exclusively for high-spending alliance leaders. This is not a general chat. It is where leaders whose spending decisions shape entire alliances' competitive outcomes connect, share coordination strategies, and learn from players managing similar budgets.
The Short Version
- Faction stacking (five heroes from one faction) is the fastest way to boost formation power.
- Concentrate investment into one faction before branching out. Diluted spending produces less power.
- Vehicles (Hercules, Destroyer) are an undervalued formation power source at higher levels.
- Hall of Honor turns maxed heroes into permanent roster-wide stat boosts.
- HP research provides the highest formation power return per badge invested.
Formation power compounds when investment stays consistent through event cycles. That consistency is what top accounts get right.
