Look, if you’re reading this, you’ve probably stared at your phone screen for two hours wondering why your heroes are melting in seconds. You are stuck. Last War Frontline Breakthrough 13 isn't just another level; it’s a gatekeeper. It is that specific point in the campaign where the game stops holding your hand and starts demanding actual strategy instead of just high power numbers.
Most people think they can just out-level the problem. They can't.
I’ve seen players with higher total CP (Combat Power) than the stage requirements get absolutely shredded because they don't understand the underlying mechanics of the wave spawns. This isn't just about clicking buttons. It is about timing. It is about knowing which lane is going to collapse first and why your tank is suddenly made of wet paper.
The Reality of Breakthrough 13
Basically, this stage introduces a massive spike in enemy density that your standard "auto-battle" formation probably isn't equipped to handle. In Last War: Survival, the "Frontline Breakthrough" mode is designed to test your sustained DPS versus your frontline durability. By level 13, the enemy waves aren't just bigger—they’re faster.
Here is the thing: the boss at the end of this specific run has a localized AoE (Area of Effect) that punishes melee-heavy compositions. If you’ve been stacking brawlers without a solid back-line support system, you’re going to hit a wall. Hard. Honestly, the difficulty curve here is less of a slope and more of a cliff.
You’ve got to look at your hero synergy. Are you running a 3-2 faction bonus? If not, you’re leaving a massive chunk of stats on the table. In the early game, you can ignore the faction bonuses and just win through sheer force. At Breakthrough 13, those 10% to 20% HP and Attack buffs are the difference between a victory and a "Defeat" screen with 2% boss HP remaining.
Why Your Current Strategy is Failing
Most players fail because they treat the frontline as a static wall. It isn't. In this stage, the enemy AI targets the hero with the highest current HP percent, which often swaps your aggro in ways you don’t want. If your squishy damage dealer accidentally pulls focus because your tank took a big hit early, it's game over.
Think about your gear. Have you actually leveled up your chips? People forget about the chips. They focus on the hero stars, but the gear is where the actual mitigation happens.
The Composition Problem
I see a lot of people trying to run Murphy and Violet without enough backline pressure. It doesn't work here. You need someone like Kim or Marshall to provide that consistent "melt" factor. If the waves don't die fast enough, they stack. When they stack, your tank's armor rating becomes irrelevant because they’re taking fifty hits per second.

- The Tank Trap: Don’t just put your "strongest" unit in front. Put the one with the highest dodge or damage reduction.
- The Support Gap: If you aren't using a healer or a buffer, you need to kill the boss in under 30 seconds. Most players at this level can't do that yet.
- The Timing Issue: If you are playing on manual, you are probably "fat-fingering" your ultimates.
Wait for the wave clusters. Don't waste a massive AoE ultimate on three stragglers when a pack of twenty is about to spawn from the right side.
Detailed Breakdown of the Wave Mechanics
Wave one is a joke. You know that. It's meant to build your energy meters.
Wave two is where the trouble starts. You get a split-lane push. If your heroes are all bunched in the center, the side-lane enemies will bypass your frontline and go straight for your artillery. You have to positioning your units to "leash" these side-lane spawners.
Then comes the mid-boss. He’s a tanky bruiser who reflects a portion of physical damage. This is why players using heavy physical builds suddenly see their own heroes' health bars plummeting. If you have energy-based attackers, save their skills for this specific window.
The Final Push
The final boss in Last War Frontline Breakthrough 13 has a charging mechanic. You’ll see a red telegraph on the ground. If you don't have a stun or a knockback ready to interrupt that cast, your frontline is going to take a 400% damage hit. It's brutal.
Most successful runs I’ve analyzed use a "sacrifice" play or a perfectly timed shield. If you have Mason, his ability to pierce through the front rank to hit the boss early can help soften the target before the final showdown.
Gear and Research: The Invisible Buffs
Let’s talk about the Research Center. Are you keeping up with your Hero combat buffs? Honestly, a lot of players neglect the "Special Forces" or "Hero" trees in the lab because they’re busy chasing base upgrades.

If your research is lagging more than two levels behind your HQ, you’re essentially fighting with one hand tied behind your back. You need the "Damage vs. Zombies" nodes maxed out for your current level.
- Check your drone. Is it set to attack or defend? For Breakthrough 13, you usually need the drone on "Attack" to help clear the mobs before they overwhelm the tanks.
- Look at your components. If you have level 3 or 4 components, make sure they are on your primary DPS, not spread out thinly across five heroes.
- Don't sleep on the "Rapid Fire" or "Crit" buffs if you’re using a gun-heavy lineup.
The "Secret" to Clearing it Without Spending Money
You don't need to be a whale to beat this. You just need patience and a bit of "micro-management."
Try this: turn off auto-battle.
I know, it’s annoying. But auto-battle is stupid. It fires off ultimates the millisecond they are ready. If your hero fires a massive rocket at a single enemy with 1 HP left, you've wasted that cooldown for the next 15 seconds. In a stage as tight as Breakthrough 13, that’s a death sentence.
Wait until the enemies are physically touching your frontline. Then, and only then, unleash your AoE. This ensures maximum damage per skill use.

Also, consider your hero levels. If you are stuck, try "resetting" a lower-tier hero to get the EXP back and dumping it all into your main carry. A level 60 Kim is worth more than five level 40 backups. Focus your resources. It’s better to have one god-tier unit than five mediocre ones.
Common Misconceptions
People think the "recommended power" is a requirement. It’s a suggestion. I’ve seen people beat this stage with 50k less power than recommended by using a heavy control (CC) team. Stuns are king here. If the enemy can't move, they can't hurt you.
Another myth is that you need all UR (Ultra Rare) heroes. False. A highly ascended SSR (Super Secret Rare) often outperforms a base-level UR because of the skill unlocks and stat multipliers from the "stars." Don't bench your 4-star Scarlett for a 1-star Murphy just because he’s a gold hero.
Actionable Steps to Beat Breakthrough 13 Right Now
If you are staring at the "Defeat" screen right now, do these four things in order:
- Audit your formation: Switch to a 3-2 faction split to trigger the HP and Attack bonus. If you are getting melted, prioritize the 3-tank/2-support setup just to survive the timer.
- Manual Control: Replay the level and hold your ultimates for the wave clusters at the 30-second and 15-second marks.
- Gear Swap: Take the best gear off your 4th and 5th heroes and put it all on your main tank and main DPS. Make them "raid bosses" in their own right.
- Drone Components: Focus on "Rate of Fire" and "Accuracy." If you can't hit the fast-moving waves in the second half of the stage, you're toast.
The game is designed to make you feel stuck so you’ll buy a pack. Don't fall for it unless you really want to. Most of the time, the solution to Last War Frontline Breakthrough 13 is just a slight adjustment in how you time your skills and how you distribute your existing gear.
Go back in, watch the enemy spawn patterns, and wait for the right moment to strike. You've got this.
