Hey there, commanders! If youāre reading this, youāre probably tired of watching your damage numbers tickle the Code Boss while other players in your alliance are pulling millions. Trust me, Iāve been there. Now, Iāve cracked the code on how to maximize your damage as a F2P tank main.
Hereās the thing most players get wrong: that full UR squad youāve been running for PvP? Itāsnotwhat you want for boss fights. When youāre up against Code 64, Code 30-something, or Code 80-something, your goal isnāt survivalāitās raw, unadulterated damage. And that means rethinking everything you know about team composition.
Letās dive in.
Understanding the Code Boss Meta
Before we get into specific lineups, letās talk about what makes Code Boss fights different from everything else in Last War.
In PvP, you need balanceāa tanky frontline, solid DPS, maybe some sustain. In boss fights? Every hero that isnāt contributing damage is a wasted slot.That means saying goodbye to pure defenders who donāt pack a punch. Iām looking at you, Murphy .
The other key factor? Troop type bonuses matter more than you think. Running 5 tanks gives you a juicy +20% HP, Attack, and Defense boost . But sometimes, breaking that bonus for the right hero actually increases your overall damage output. Itās about knowing when to stick to type and when to splash.
Also worth noting: troop type match ups play a role here. Tanks deal 20% bonus damage to Missile Vehicles . Keep this in mind when youāre picking your targets!

The F2P Tank Core: Heroes You MUST Build
Every F2P tank player needs to understand which heroes are non-negotiable investments. Hereās your priority list:
Kimberly ā The Damage Queen

If you only invest in one hero, make it Kimberly. Sheās the undisputed queen of area damage in Last War . Her third skill unleashes devastating AoE that can shred boss adds and chunk the main target. Plus, her Exclusive Weapon provides a 10% base stat boost per level that scales through her entire kit .
Investment priority: MAXIMUM. Every universal gold shard goes to Kim until sheās at least 4 stars .
Marshall ā Your Team Force Multiplier

Hereās a hero that often gets overlooked by new players. Marshall isnāt a traditional tankāheās a damage amplifier. His second skill increases the attack of your entire squad for 8 seconds . When youāre trying to burst down a boss in a limited time window, this buff is absolutely massive .
Investment priority: HIGH. Level him alongside Kimberly.
Mason ā The Early Game King with UR Potential

Mason starts as an impressive early-game damage dealer who can outshine even legendary heroes in the beginning . But hereās where it gets interesting: when you promote him from SSR to UR in Season 1, he becomes significantly stronger .
That said, if you already have Kimberly and DVA built, Mason becomes less critical. Heās a fantastic budget option, but donāt feel obligated to UR him if your other carries are ahead.
Murphy ā Your Reliable Defender

Murphy brings excellent defensive capabilities and is very F2P-friendly . He buffs your front-row heroes against physical damage, which is valuable in boss fights where youāre running an off-type hero that needs protection.

Base Tank Formation: The Foundation
Hereās your starting point for any Code Boss fight. This formation works well against both Tank and Aircraft Code bosses:
|
Position |
Hero |
Role |
Why Theyāre Here |
|
Front Row |
Kimberly |
Damage |
Your primary carryāher AoE shreds |
|
Front Row |
Murphy |
Defense |
Keeps your frontline alive |
|
Back Row |
Marshall |
Support |
Team-wide attack buff |
|
Back Row |
DVA |
Damage |
Single-target burst for bosses |
|
Back Row |
Mason |
Damage |
Additional DPS (replaceable) |
Why this works: Marshallās damage buff benefits everyone, DVA brings her devastating single-target burst , and Kimberly handles the wave clear and consistent damage. Murphy gives you just enough survivability to keep everyone alive through the fight.
The DVA question: You might be wonderingāwhy run DVA in a tank squad? Sheās an Aircraft hero, so you lose your 5-tank bonus. Hereās the deal: DVAās single-target damage is so exceptional that itās worth sacrificing the 20% bonus . Her precision targeting makes her the ultimate boss killer. Once her Exclusive Weapon is unlocked, she becomes even more deadly.

Missile Code Boss (Code 64): The Adam Tech
When youāre facing Code 64 (the Missile boss), things change slightly. This is where Adam comes into play.
Why Adam?

Adamās second skill, āCounter Defense,ā puts him into a counterattack state. When he has4 stars or more, the skill text reads: āThe units in the first rowā receive the counterattack benefit . That means if you position him correctly, he can massively boost your frontlineās damage output through counterattacks.
Hereās the lineup for Code 64:
|
Position |
Hero |
Role |
|
Front Row |
Kimberly |
Main damage |
|
Front Row |
Another Tank (Murphy/Williams) |
Survival + Adam synergy |
|
Back Row |
Marshall |
Attack buffer |
|
Back Row |
Adam |
Counterattack driver |
|
Back Row |
Mason/DVA |
Flex damage |
Positioning is key: Adam goes in the back row, but his skill affects your frontline. The counterattacks from your front row heroes add significant damage over the course of the fight.
Alternative approach: If you donāt have Adam built, you can run a 4+1 formation with DVA instead. The damage is still solidājust not as optimized for Missile bosses specifically.

Season 3+ Ultimate Tank Formation
Once you hit Season 3, everything changes. Scarlett upgrades to UR, and she becomes an absolute monster for tank formations . This is the definitive F2P tank squad for Code bosses:
|
Position |
Hero |
Notes |
|
Front Row |
Scarlett (UR) |
New core damage dealer |
|
Front Row |
Murphy/Williams |
Defense anchor |
|
Back Row |
Marshall |
Attack buff |
|
Back Row |
Kimberly |
AoE damage |
|
Back Row |
DVA |
Single-target burst |
For Aircraft Code bosses in Season 3, swap Kimberly out for another DPS option like Tesla or keep the same setup depending on your specific damage needs.
Scarlettās UR promotion makes her competitive with top-tier heroes . For F2P players who have been patiently building her, Season 3 is your payoff moment. She brings both durability and damage, letting you maintain type bonuses while still pushing high numbers.
Budget Alternatives While You Build
Not everyone has all these heroes at 4+ stars. Hereās what to use while youāre working toward the meta teams:
- Marshallā Already mentioned, but worth repeating. He works inanyformation .
- Scarlett (pre-UR)ā A solid budget tank for early game .
- Masonā Strong early-game damage dealer .
- Monicaā Pure support with healing. Great for early to mid-game sustain .

Ā
Resource Management for F2P Players
Hereās the hard truth: as a F2P player, you canāt build everyone. You need to be strategic about where your resources go.
Priority Order:
- Kimberly to 5 starsā Sheās your main carry. Nothing else matters until sheās maxed .
- Marshall to 4 starsā His damage buff scales with stars .
- DVA investmentā Start building her on the side. Youāll accumulate her shards through Tavern pulls .
- Murphy and Williamsā Use their specific shards from stores, not universal ones .
Ghost Operations and Events
Donāt sleep on Ghost Operations when they become available (around day 200). Theyāre a fantastic source of hero shards for locked heroes you donāt own yet . Also, Thursday operations can give you shards for heroes even if you havenāt unlocked them .
Skill Upgrade Priority
For support heroes like Marshall, prioritize their active skills first. For damage dealers like Kimberly and DVA, focus on their passive skills that scale damage .
Ā
Common Mistakes F2P Players Make
Let me save you some pain by pointing out the traps Iāve seen (and fallen into myself):
ā Spreading resources too thin
You donāt need 10 decent heroes. You needone killer squad. Focus everything on your top 5 .
ā Ignoring Marshall
āHeās just a supportā ā Iāve heard this a hundred times. Then people finally build him and wonder why their damage suddenly spiked .
ā Forgetting to check tier updates
The meta shifts. What was S-tier last month might be B-tier now . Stay informed.
ā Sticking rigidly to 5 of the same type
Sometimes breaking the bonus for DVA is the right call. Donāt let perfectionism hurt your damage.

Ā
Which Formation Should You Use?
Hereās my recommendation based on where you are in the game:
|
Your Situation |
Best Formation |
|
Pre-Season 1, F2P |
5 tanks: Kimberly, Murphy, Marshall, Mason, Violet/Scarlett |
|
Pre-Season 3, have DVA |
4 tanks + DVA: Kimberly, Murphy, Marshall, Mason, DVA |
|
Code 64 (Missile) |
Adam variant with counterattack setup |
|
Season 3+ |
Scarlett UR core formation |
Test them yourself!

Final Thoughts
Building a boss-killing tank squad as a F2P player isnāt about having the flashiest UR heroesāitās about synergy, smart investments, and understanding the mechanics of each Code fight.
Now go melt some Code Bosses, commander.
