Helldivers 2 Exo Experts Warbond New Exosuit Mechs | Should you choose EXO-51 Lumberer or EXO-55 Breakthrough?
Category: Helldivers 2 Posted: Apr 29, 2026 Views: 26
Players, Helldivers 2's Exo Experts update yesterday introduced two brand-new mechs: EXO-51 Lumberer Exosuit and EXO-55 Breakthrough Exosuit. These two mechs have distinct styles, but both are well-balanced. Let's explore their performance.
Basic Information
EXO-51 Lumberer is equipped with a 25-round anti-tank cannon and a flamethrower, serving as a heavy anti-armor unit primarily focused on clearing bugs.
EXO-55 Breakthrough, on the other hand, features a 69-round flat cannon and a massive ballistic shield. It's mainly used for frontal assaults.
In the latest version, the durability of all mechs has been doubled. While enemy damage to durability has increased, the overall survivability of the mechs is actually stronger.

EXO-51 Lumberer Review
Performance and In-Game Data
EXO-51 Lumberer's anti-tank cannon can kill a Bile Titan in just two shots. If it's a Charger Behemoth, two shots are enough to take it down, and dealing with an Impaler is also easy. However, it can't penetrate Bile Titan Bug Hole yet.
25 rounds of ammunition can kill approximately 12 Bile Titans, demonstrating impressive sustained firepower.
Its flamethrower has a very ample ammo capacity, making it extremely efficient at clearing bugs, ideal for close-range sustained damage. The flamethrower and anti-tank gun form a perfect combination for single-target elimination of large enemies and clearing out smaller ones.
Performance Against Bugs
When fighting bugs, EXO-51 Lumberer can consecutively kill Bile Titans, Impalers, and Charger Behemoths. The mech only started smoking before its flamethrower was used up to half its capacity. Even when ammo is depleted, the mech's stomp damage can crush medium-sized Terminids like Hive Guard.
This mech's durability is significantly better than the older version, allowing it to withstand heavy fire for a considerable time.
Faction Suitability Recommendations
EXO-51 Lumberer is arguably the best choice for dealing with Terminids. It perfectly counters the Bile Titan, its flamethrower is excellent at clearing bugs, and it's basically designed specifically for Terminids.
However, it's not highly recommended against Illuminates. It's only effective against Harvesters, so its overall efficiency is low.
It's slightly better against Automatons than against Illuminates, but its flamethrower is less effective against the robots' metallic bodies.
EXO-51 Lumberer is best suited for high-difficulty Terminids missions and is currently the strongest mech against Terminids.
EXO-55 Breakthrough Review
Weapons and Shields
EXO-55 Breakthrough's flat cannon deals extremely high damage, but requires multiple hits against large enemies. Reloading is also relatively slow; after the magazine is empty, you need to manually reload by pressing the R key. This animation is quite long, so it's recommended to reload early when it's safe to do so.
The ballistic shield provides additional durability, with its remaining value displayed in real-time on the interface. The shield can also be used for melee hammer attacks, dealing considerable damage.
Testing shows the shield's total durability far exceeds the mech's normal lifespan, making it virtually indestructible.
Performance against Automatons
When facing Hulk, the flat cannon aimed at the enemy's weak point can instantly kill them.
However, caution is advised when facing Factory Strider. Its cannon turret deals extremely high damage, capable of destroying a full-health mech in one hit. You must either exit the mech and use weapons like Recoilless Rifle to destroy the turret, or prioritize firing at the turret from inside the mech.
Performance against Illuminate
Using the shield for melee combat, a single hit can kill an Overseer, with swift and decisive movements. Two shots from the flat cannon are sufficient to kill an Overseer, and it's highly effective against groups of smaller enemies.
A sustained burst of fire is required against Harvester, but it remains manageable. Overall, EXO-55 Breakthrough is extremely powerful in Illuminate mission. Its shield effectively blocks a large number of small projectiles, and close-range kills of elites are incredibly satisfying.
Performance Against Bugs
When facing a Bile Titan with the flat cannon, it takes approximately 6 shots to kill it. Against Charger Behemoth, it takes about 4 shots, with a face shot being enough for a kill.
Even when ammo is depleted, close-range combat with the shield can kill Charger Behemoth.
Under multiple Bile Titans attacking simultaneously, the mech started smoking significantly later than expected. Its durability performance was surprisingly good.
Mech Combat Tips
The mech's stomp attack is enough to instantly kill most small enemies. Also, although the mech's durability is increased, avoid directly tanking extremely high single-shot damage to avoid unnecessary risks.
EXO-51 Lumberer is suitable as an anti-heavy armor core, following behind teammates clearing lanes to eliminate Bile Titans at specific points. EXO-55 Breakthrough is best suited as a frontal assault shield, drawing fire and eliminating elite enemies at close range, while teammates provide flank support.
Additionally, it's recommended that players carry a support weapon next to their mech. When encountering dangerous targets, dismount to eliminate them before returning to the mech.
Mech Comparison
Comparing these two new mechs side-by-side, EXO-51 Lumberer is better suited against Terminids faction, while EXO-55 Breakthrough is better suited against Illuminate. Both excel at clearing out smaller enemies.
In terms of ease of use, EXO-51 Lumberer is simpler because of its ample ammo. EXO-55 Breakthrough requires more attention to reload timing and shield orientation.
EXO-51 Lumberer boasts formidable firepower. However, EXO-55 Breakthrough's melee shield attack mechanism offers a completely different and satisfying experience. Whichever you prefer, the new Warbond is worth unlocking with your Helldivers 2 Super Credits.
Decide based on your preference. Good luck with the game!
