Squad Builder & Formations
Last War: Survival — Counter system, meta formations, and when to build what
The counter triangle
Everything in Last War PvP revolves around this rock-paper-scissors mechanic. Building around it is the single most important strategic decision.
Same-type lineup bonuses
| Heroes of same type | HP / ATK / DEF bonus | Note |
|---|---|---|
| 3 same type | +5% | Minimum for any bonus |
| 3 same + 2 other | +10% | Mixed squad option |
| 4 same type | +15% | Strong — 1 flex slot |
| 5 same type (full) | +20% | Maximum — recommended |
Always aim for 5/5 same type on your main squad
The +20% bonus to HP, ATK, and DEF is enormous. A full same-type team with average heroes will often beat a mixed team of individually stronger heroes. Only break the 5/5 for specific hybrid builds in Season 4+ when you have Tactics Cards and Exclusive Weapons to compensate.
Meta formations by squad type
When to break the 5/5 type rule
From Season 4 onward, Tactics Cards and Exclusive Weapons can compensate for losing the +20% type bonus. The key threshold: a hybrid is worth it only when the off-type hero's individual contribution exceeds the 5% stat loss for your entire squad. In practice, this means only heroes with strong Exclusive Weapons at high star levels should be splashed into off-type squads.
Multi-squad strategy (Season 3+)
By Season 3, most competitive players run multiple squads for 3v3 and Alliance Wars. The standard approach:
Squad 1 (main): Your most invested squad. Usually Aircraft in the current meta — it counters the most common opponent type.
Squad 2: Tank squad — naturally beats Missile and is the easiest to build since you started with it.
Squad 3: Missile squad — counter-pick against Aircraft-heavy opponents. Build this last.
Reading the matchup before battle
Always scout your opponent before sending squads. In 3v3 or Alliance Wars:
— If they run mostly Tanks → send Aircraft
— If they run mostly Aircraft → send Missiles (or Anti-Air Tank hybrid)
— If they run mostly Missiles → send Tanks
— If they run mixed → lead with your strongest squad and adapt

Code Boss formations
Code Bosses are world-map events that give major rewards. Each boss type grants a +50% damage bonus to one specific squad type. Bring the wrong squad and you're doing half damage — always match the boss.
Hero investment priority
General rule: DPS first, tank second, support last
Your damage dealers (Kimberly for Tank, DVA for Air, Fiona/Tesla for Missile) should receive gear, skill medals, EXP, and shards before anyone else. Higher damage improves performance across all game modes and accelerates resource gain, which feeds back into faster overall progression. Upgrade damage pieces before defense pieces on gear. Don't neglect ore production — gear upgrades depend on it.
Upgrade your type center building
The Tank/Air/Missile Center buildings provide stat bonuses to all heroes of that type, plus march speed. Upgrade your main squad's center first. This is a base-wide multiplier that affects every battle.
Formation Position Map
Each numbered squad slot maps to a specific spot on the battlefield. Position 1 faces the enemy first. Position 5 is the safest backline slot. Numbers match what you see on your in-game formation screen.
Position reference
| Pos | Name | Risk | Role | Tank squad | Air squad | Missile squad |
|---|---|---|---|---|---|---|
| 1 | Front Left | High | Primary tank — first contact, absorbs most hits | Murphy | Lucius | Adam |
| 2 | Front Right | High | Off-tank — second frontline, shields position 1 | Williams | Carlie | McGregor |
| 3 | Back Left | Low | Primary DPS — deals damage from back row safety | Kimberly | DVA | Fiona |
| 4 | Back Center | Low | Secondary DPS — sustained damage, protected | Stetmann | Morrison | Tesla |
| 5 | Back Right | Safe | Buffer/Support — safest slot, must survive full fight | Marshall | Schuyler | Swift |
Hybrid squads: off-type hero always goes to position 2
When you splash an off-type hero into a squad (e.g., Murphy in an Air squad), put them in slot 2 — front right. Murphy's raw tankiness fills that off-tank role better than Carlie in late-game metas. The rest of the squad stays in standard positions.
Code Boss exception: Marshall moves to position 1
In PvP, Marshall stays in position 5 (safest — maximizes his buff uptime across the whole fight). For Code Boss fights (87 · Frankenguy, 39 · Mammoth, 64 · Gorilla), move Marshall to slot 1 (front) — he needs to tank the boss's heavy AoE. His squad-wide buffs still apply from the front row.
