Alien Harvesters are Alien capital ships, introduced in the very first Alien Decimation event. They're extremely powerful and very hard to destroy.

These ships have a whale-like shape, they're armed to the teeth with extremely powerful weapons, and can sometimes deploy various swarms to defend itself. It also unleashes a powerful shockwave triggered at certain points after taking a particular amount of damage.

Its looks don't deceive, being lethal and bigger than a Javelin Flagship.

When destroyed, these ships drop various rewards: crafting materials, blueprints for Xeno versions of weapons, even reusable items such as Ranger Swarms, Charger Swarms and Gladiator Swarms.

Unlike other ships, the Harvester and any boss targets will fully heal and reset to full health if it's not destroyed in a single battle. They can be fought by one to two players at the same time, depending on the target.

In Geir's Fortress, players are able to see that the Harvester indeed does have a 360 degree firing arc.



The Alien Harvester is a powerful capital ship. Rebels should not take it lightly.


It fires eight Rift Beams from its "spine" at extremely long range. These beams inflict continuous damage for 4 seconds; however, they can be blocked by other ships and take 3 seconds to reload, allowing potential shield-switching. There are also two hard-points on its "back" that fire piercing Flux Rays in pairs, which deal much less damage. At close range, two Photon Gatlings start to fire on player ships, punishing them with massive DPS.

They also unleash Alien swarms from its sides, namely the aforementioned Ranger Swarms as well as the close range Gladiator Swarms. These squadrons are no different to ones from Alien hives and will flank the player from both directions before closing in.

When its health is reduced to 75%, 50%, or 25%, it will start charging up a massive shockwave that takes 8 seconds to fire. Along with the impressive visuals, the shockwave inflicts decent damage - enough to deplete a good amount of Metaphase Shields.

When destroyed, it also releases a similar shockwave.


Use Covenant Cruisers with Manifold Missiles or Infernal Gatling Rays - other cruisers can suffice, but Covenant and Heretics should be used for best results. Just ram the Harvester. Expect your fleet to be almost completely destroyed at the end of battle, if you are doing 80s. If you are doing 70s or 75s you might be able to survive to do multiple.

Dominion carriers can destroy level 70 Alien Harvester variants, using cruisers or battleships to destroy squadrons and absorb damage from the Harvester's lasers and projectiles. Recharging shields are required. Gladiator Swarms are immensely helpful as well. This usually results in minimal damage sustained if executed correctly, players need to destroy squadrons and shuffle their ships as they recharge their shields. On top of that, their fleet needs to be moving to stay away from the Harvester and be mindful of their piercing weapons that could delay shields from recharging.

However, the kiting tactic is extremely hard to pull off.


The Barrage Harvester is an Alien Harvester that has sacrificed movement speed for long-range weaponry. They are vulnerable when rushed but excel at long ranges.


The solo version contains similar weaponry as Barrage Hives. However, it uses Heavy Viper Missiles, which are Viper Missiles that fire twice as many shots, and Quantum Gatlings, which deal more damage that the regular version.

They also carry a Stasis Field which slows your hulls so you receive even more DPS from the Harvester as you rush in, similar to the Barrage Hives. Cutters are recommended due to their stasis resist, reducing the damage they take as they rush in.

They originally used to carry shockwaves in their first iteration, but no longer do in their second and third iteration. From the third iteration onwards, they launch Charger Swarms with greatly increased damage and the ability to bypass shields. However, these have a very large minimum range, equal to the maximum range of the Harvester's Viper Missiles.

This version of Harvester can barely move just like the Barrage Hives, and can be considered as a "stationary" object. Despite this, it is really difficult to kill because it is relatively hard to get in range without taking heavy damage.


The co-op version is very strong and is designed to be taken on by 2 players at once.

It has removed its Eradication Beams from the solo version in exchange for more explosive weaponry, the Stalker Missile and the Crawler Torpedo. Both of these weapons have large AoE that can easily damage multiple ships at once.

Unlike the solo version, it does not have the Pulsar Charger special.

The old Co-op Version was guarded by an additional 6 Alien Hives armed with Discharge Beam and Gladiator Swarms. Now, the Hives have since disappeared, leaving only the harvester itself.


For the solo version, a mix of Punisher Cruisers and Decimator Cutters is recommended: the cruisers absorb the damage while the cutters deal the damage. While they have a lot of DPS, Annihilator Battleships and Exterminator Destroyers are simply too slow for the job; too much damage is taken during the rushing phase. Do not let any of your ships die in the process. Maintaining the full firepower of your fleet is essential to defeating the Harvester as it has a lot of health.

For the co-op version, a combination of Punisher Cruisers and high-DPS ships such as Annihilator Battleships and Exterminator Destroyers work well. Surprisingly, cutters do not work well against this Harvester as its long-range weaponry are weak compared to its short-range ones, which cutters could not outrange. Suppressors are essential for taking out the deadly swarms throughout the battle.


The Reaper Harvester is an Alien Harvester with great speed, but less damage overall.


Bearing somewhat of a resemblance to the Alien Reapers, the solo version foregoes certain weapons in the Barrage and Alien Harvesters for a few new additions. It is armed with 3 Rebound Rays, a long-range version of the Reverb Ray, as well as 3 Heavy Ion Gatlings. It also has 6 Rift Beams which deal decent damage. Lastly it launches 4 Gladiator Swarms, though the range is smaller than the normal Alien Harvester.

While it lacks the stasis field of its Barrage counterpart, its combat speed is extremely high, making it nigh impossible to run away from it unless fast ships like Cutters or Cruisers are used.

They also contain a shockwave that triggers at 75%, 50%, 25% and 0% health.


The Older Co-Op Version has swapped out its Rift Beams for 3 Vulcan Beams, and also contains 3 Ion Gatlings and 3 Quantum Gatlings as well. It retains its 3 Rebound Rays, the large speed and its shockwaves.

It also launches 4 Gladiator Swarms and 4 Charger Swarms.

With the introduction of the Crafting Event, the co-op Reaper Harvester has regained its Rift beams and lost its Vulcan Beams and Quantum Gatlings, now resembling the solo version.


A mix of Punisher Cruisers and Annihilator Battleships can quickly dispatch the Reapers and the Harvester in this fleet. Space out your ships to avoid Rebound Ray bounces and turn on AI mode to dodge the gatlings. Never let your carrier get in shockwave range. The Harvester likes to move towards your carrier so be sure to block its movement with other ships.


The Unknown Fortress Alien Harvester that appears in Geir's Fortress is Geir's elite guard and is armed with a wide array of weapons. It is also quite fast although it has really bad acceleration (takes a while to enter its top speed). It is invulnerable to the mines that are set up throughout the outskirts of the Fortress.


It is armed with 2 Heavy Viper Missiles like the Unknown Barrage Harvester, as well as 2 Crawler Torpedo, a variant of the Creeper Torpedo, and 6 Stalker Missiles, similar to Scatter Missiles,. It also has a Pulsar Charger that triggers at 75%, 50%, 25% and 0% health, though it rarely gets to fire off all 4 shockwaves because of the rate its health can be depleted.

It also launches 6 Charger Swarms, 2 more than the regular Barrage Harvester.

Surprisingly, its weapons do not seem to do a lot of damage, and it is possible for even Demon Corps Ships to destroy the Harvester.

The Harvester only takes up around 15% of the health of the Fortress however, and is usually not the main problem. The modules in the base where this Harvester is held are usually the ones that deal the most damage.


Take out the Harvester as soon as possible with raw DPS to minimize the number of shockwaves it unleashes. Spread out your ships to avoid AoE damage. If you do it correctly, none of your ships will have completely depleted shields by the time you destroy the Harvester.



  • They're currently the most powerful starship in the whole game.
  • It is difficult to pin down the exact firepower and armor on the Alien Harvester as it was being constantly changed throughout the event, particularly at the beginning.
  • The Reaper Harvester was the first level 100 target to be added to the game.
  • The Co-op Barrage Harvester used to also contain Quantum Gatlings and Gladiator Swarms, but they have since been removed, causing it to be almost identical to Geir's elite guard.
  • The Co-op Reaper Harvester used to also contain Vulcan Beams, Quantum Gatlings and Charger Swarms, but they have since been removed, causing it to be identical to the solo version.
