The unseemly marriage of a Corpus sentry turret and a Sentient drone, this unit alternates between Arca Plasmor blasts and a devastating focused beam weapon.

Amalgam Arca Kucumatz are enhanced Amalgam Kucumatz equipped with an Arca PlasmorCrpShotgun.png Arca Plasmor. They can only be found in Secret Corpus Laboratories.

Like its normal counterpart, Arca Kucumatz can unleash a deadly laser blast after a brief charging time.


  • They occasionally charge up a blue beam for 3 seconds, after which it deals heavy damage to the player over 4 seconds.
  • During downtimes, they shoot the player with their Arca PlasmorCrpShotgun.png Arca Plasmor, getting within 5m to do so.


  • Since they are classified as SentientFactionIcon b.png Sentient, they will be hostiles to normal Amalgam and Corpus units.


  • Kucumatz (or Ququmatz) is a name of a creator deity from Mayan mythology, meaning "Quetzal serpent" and roughly equivalent to Quetzalcoatl of the Aztec mythology.
