Lambent Berserkers are larger and more deadly than regular Berserkers, being vastly superior in strength, agility and durability. They also had multiple blade-like tentacles that sprouted from their backs and the ability to jump. Fortunately, their vision was just as bad as their normal counterparts and most of their attack usually consisted of charging at nearby opponents. The hide of a Lambent Berserker was far more durable than a normal Berserker; while a strike from the Hammer of Dawn burned through a normal Berserker's hide (and leaving them vulnerable while it was seared), a Lambent Berserker's hide was not affected at all.
The only way to kill a Lambent Berserker was to attack its exposed chest cavity, which was usually protected by its ribcage; the ribcage only opened when the Berserker prompted a charge. When significant damage was dealt on its core, it would show signs of pain before attacking again. Four of these "assaults" were sufficient enough to kill a Lambent Berserker, but each assault increased its overall destructiveness.
After the first assault, it would begin using a jumping ground-pound attack that would splatter Imulsion near the point of impact; after the second assault, it would begin to leak Imulsion; upon the third assault, it would leave behind walls of Imulsion vapours wherever it went. After a fourth critical hit, the Lambent Berserker would begin to self-destruct, flailing wildly before violently exploding. These attacks are capable of instantly downing a player, and the extra assaults are capable of an Execution.
In 17 A.E., a Lambent Berserker emerged from the trunk of a stalk during the Battle of Anvil Gate. Surprised by the Lambent Berserker, it killed several nearby COG Gears before sending a car flying at Marcus/Dominic's position (depending on who went out to rescue Samantha and Anya), which they narrowly avoid. Damon S. Baird attempted to use the Hammer of Dawn on the Berserker, although the first two strikes missed because of the deteriorating aiming system. A third blast managed to hit the Berserker and it was presumed dead.
When Delta Squad retreated back into Anvil Gate, the Lambent Berserker revealed itself still alive and jumped over the fort's fortified gates. Delta Squad warned everyone to retreat back deeper into the fort while they dealt with the Berserker. During the battle, Delta Squad noticed its weakness and took advantage of it, finally managing to kill it after a prolonged battle.
On Horde 2.0, Lambent Berserkers can appear during Lambent waves during the boss levels. Much like Berserkers, you should move away from your base if it appears as they will instantly destroy any fortification you build when walking or charging.
Lambent Berserkers are killed by shooting at their Imulsion core. Whenever the Berserker makes an attack, its rib cages will open and reveal an Imulsion core, which must be shot at enough times. When you deal enough damage, the Berserker will stumble for a bit. During the first phase, the Lambent Berserker is much like a normal Berserker, jumping and running all over the place. On the second phase, it will splatter Imulsion (simply obscuring the screen). On the third, it will begin to leak a small amount of Imulsion which is capable of damaging and killing players. On the final phase, it leaves behind walls of Imulsion vapors, similar to the leaking Imulsion on phase 3 but deals far more damage. The core can be opened instantly by attacking the Berserker with fire (from Incendiary grenades, the Scorcher or Hammer of Dawn).
If playing with any Mutations, Super Reload is recommended to deal with Lambent Berserkers as it is possible to kill them off in one Super Reloaded Lancer clip, provided that all of the shots hit the core whenever it attempts to attack. Unlike normal Berserkers, Instagib Melee will not kill Lambent Berserkers in one hit.
Behind the scenes
- Lambent Berserkers can appear in Horde 2.0's boss waves, although the chances are somewhat low due to the game potentially spawning Brumaks, Berserkers or Gunkers instead. It is often considered the hardest boss to deal with.
- Much like Berserkers, Lambent Berserkers in Horde can be killed normally without dealing with the Imulsion core. This isn't recommended however, since the attacks deal 10% of their normal damage.
