Introduction

The Cyst is a Kharaa foundational structure created by the Alien Commander. It is a luminescent, pustule-like organic growth with pulsating roots around it.

As the most fragile organ found within any Kharaa habitat, the Cyst can proliferate extremely rapidly. A parent is first grown around a Hive, then daughter Cysts can subsequently branch outward onto horizontal surfaces. When grown, the Cyst spreads bacterial Infestation to encompass nearby terrain, allowing other Kharaa structures to sprout and grow. Cysts depend on Hives for nutrition, and should connection between daughter Cysts be severed, the outermost unconnected Cysts will begin degenerating until death; if left unattended, an entire chain can be eradicated over time. Without Cysts to regenerate the infestation, the nano-grid can slowly eliminate the Bacterium at a cellular level.

Tactical Summary - Cyst

  • Cysts have lower HP the further down the Cystchain they are.
  • Cysts are very important to the Kharaa structure chain.
  • Although inexpensive at 1 Team Resources excessive re-cysting and over cysting (placing cysts over an entire room) can be a waste.
  • Without Cysts alien structures that are not on the infestation will slowly die and not heal or be able to use abilities. Gorge structures are immune to this.
  • Flamethrowers are extremely effective of Cyst clearing!
  • Killing off large cystchains away from the alien hive will slowly kill all cysts and structures on that chain, example killing 1 cyst near the aliens only hive will cripple whole sides of the map.


Contrary to popular believe, stepping on a Cyst does not reveal you to the Alien Team. Neither on the Minimap nor in any other way, unless you deal damage to the Cyst.

Maturation

Maturation
Nutrient mist icon.gif
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.
  • Maturation can be sped up via Nutrient Mist or Heal Spray
