Mission: Undine Assault is a space 5-man fleet action mission in which Admiral Tuvok asks the players to defend one of the following, randomly selected, planets against an Undine Planet Killer: Andoria, Cardassia Prime, Ferenginar, or Gornar.


Following the beginning of a renewed conflict between members of the Alliance and Species 8472 in the Jenolan Dyson Sphere, Undine forces deploy their potent, new planet killers against several strategically-important Alliance worlds.

Players of all factions have been called to aid local forces in attempt to push through waves of Undine ships in order to close the fluidic rifts that are reinforcing the Planet Killer's defenses.

Once the rifts are closed, Captains will have a chance to take out the Planet Killer.


Mission text[]

Undine invasion fleets are targeting populated worlds in the Alpha and Beta Quadrants. Team up with other captains to push back the invaders and close the rifts to fluidic space!


  • Briefing
  • Close Undine Rifts (0/6)
2 each for the top, mid, and bottom lane
  • (Optional) Errant Rifts Closed
6 Additional "Errant Rifts" will form between the lanes. The color of the rift indicates which career path can close them without having to engage in combat with the Undine. A mismatched career will trigger a combat event at the rift. Closing these optional rifts will result in bonus marks; these rifts do not benefit from the bonus granted from closing the Undine rifts.
  • (Optional) Suppress Invasion Within Time Limit
  • Defeat Undine Invasion Ship
