Mission Navigation

Location Unknown is the thirteenth mission in the Homeworld: Cataclysm and involves an ambush by the Taiidan Imperialist.


The nav personnel of the Turanic Raiders are aboard the Kuun-Lan, but one manages to slip away from all the security and sets a bomb aboard...


  • Destroy Enemy Ships
  • Support Faal-Corum


Unfortunately, things went wrong. It seems the Turanic Raiders placed a saboteur aboard the Kuun-Lan to disable it and give the astrogation data to the Taiidan Imperialists.

At the end of the prior mission, players should take the time to dock their strikecraft and smaller vessels aboard their Carriers, which will not have their hangars disabled at the start of the mission. If this is not done, this can make the mission significantly harder, as the player won't be able to launch Workers or other vessels from the Kuun-Lan. Workers will help repair the Kuun-Lan faster, while Sentinels can be used to provide force fields around the Kuun-Lan to protect it.

Depending on the mission difficulty, there may be a large enemy force present here. Simply attack the incoming Heavy Cruisers and Destroyers with your own Destroyers and Hive Frigates, while using your ACVs and Multi-Beam Frigates to attack the incoming fighters, which include Attack Bombers. Ramming Frigates can also be used to push the Heavy Cruisers and Destroyers away from the Kuun-Lan if needed. The systems aboard the Kuun-Lan will slowly come back online over time and will need to be protected from the large incoming attacks.

Eventually, the Faal-Corum will arrive and provide support ships to assist. Locate the enemy Carrier and destroy it quickly. Once the enemy is defeated, regroup your fleet and harvest. Retire the free Ramming Frigates and Ion Cannon Frigates if you wish, as these may take up undesired space in your fleet: the free Destroyers will need to be force-attacked and cannot be retired. 8 ACVs will also have been launched from the Faal-Corum and given to the player during the battle, which can be kept if needed. Leave when ready.


  • While never exactly stated, it is possible that the Kuun-Lan arrived in the Great Nebula, since this mission shares the same background as the Cathedral of Kadesh. Alternatively, the nebula could be an entirely different one which looks similar. In lore, it was stated that all Somtaaw kiith members were in cryogenic sleep during the events of the Homeworld War, thus they would be unaware of the existence of the Great Nebula and assume the location to be "unknown" to them. Despite this, no canonical or official answer has been given in regards to the location of this mission.
  • If playing at Normal difficulty or above, the Kuun-Lan will constantly be harassed with fighter squadrons. Keep your ACVs focused on these, while using Destroyers to attack everything else.
  • When the Faal-Corum arrives, it will give the following ships to the player for free: 8 Somtaaw ACVs, 2 Somtaaw Ramming Frigates, 4 Kushan Ion Cannon Frigates, and 2 Kushan Destroyers.
