"Call of the Unknown" is the 25th episode of the second season of Exosquad.


Able Squad blasts its way into the alien complex, and is pursued inside by Typhonus and his troops. After a battle which is made more difficult by interior defenses, Able Squad escapes into a different section. Meanwhile the alien structure begins to grow out of the ground. After the exosquad has blasted its way out and come to the aid of the Jumptroops with Professor Algernon, the spire begins emitting great energy waves.

  • Upon seeing the spire:
Algernon: "It's... breathtaking."
Butler: "Let's just hope we're all breathin' when this one's done."

Significant events, revelations, and other notes[]

  • I am of the opinion that this episode would have been the basis for the third season of ExoSquad, had one been made. The strange occurrences at Chaos in "Beyond Chaos" could well be some alien race summoned by the transmission that is sent in this episode.
  • Why did Exofleet's explosive charge fail to breach the door? Was Typhonus's explosive charge more powerful or was the area choosen less resilient?
  • The alien complex seems to be almost entirely comprised of organic technology.
  • What is the purpose of the alien complex? Was it a former outpost or colony for the beings that created it? Or was it simply left behind milennia earlier so that when humans advanced far enough to activate it, it could alert its creators?
  • Timeline of the Neosapien base on Ceres.
  • Algernon invented Exofleet's cypher system.
  • In "Call of the Unknown" and "Heart of Mars" the Jumptroop Dropship was able to approach Mars, remain in orbit, and leave the planet without using a Cloaking Device. The Mars Fleet never appears, combat is limited to the ground.
