The Harvester is the Kharaa resource collection structure created by the Alien Commander. It appears as an large, immobile, and leech-like alien organism with bony carapace lining its back and a large luminescent membrane surrounded by bone extrusions.

The Harvester is created by spreading Infestation onto a Resource Nozzle and sprouting directly atop it. Once grown, it will periodically gather Team and Personal Resource until destroyed. The amount of existing Harvesters is shown to both Kharaa players and the Alien Commander, as shown in-game: Harvester Icon

NS1 Comparison

The Harvester retains the bulbous-ness of the original design, while incorporating the new visual style of the Kharaa species. The bony growths, glowing sac and finger like tentacles are recurring themes in the alien designs. While the Harvester is meant to feel like a living part of the alien ecosystem, efforts were made to make sure that the structure didn't look too much like a playable character.

Most Kharaa structures absorb nutrients by rooting into the Infestation. If the Infestation recedes from underneath a Kharaa structure, it will take damage over time until death or the ground is infested again.

Most Kharaa structures will mature over time, gaining extra maximum Health and Armor every second until fully matured.
  • Max health/armor and mature time vary between different structures.
  • At 50% maturity, the structure is prefixed as "Grown".
