The PC Clan ranked 71st in the last event Cicero Crisis (Storm tier) let's try to aim for the same!

Event Details


- You will receive a Blueprint from The Lotus for the Tethra Cipher Key. This will be your key to a new tileset, the hidden Grineer Shipyards. In order to craft the Cipher, you will need to collect unique data fragments by playing the Tethra's Doom Interception Mission on Earth.

  • Once you have the necessary resources, you can craft the Tethra Cipher. Your Blueprint will not be consumed.
  • Use your Cipher to open the Grineer Shipyards and play the NEW Hijack Game Mode.
  • In Hijack, you'll need to find a Fomorian Power Core which can be released by activating the control panel.
  • Once released, the core will become unstable and its health will begin to degrade. If the core runs out of health before it reaches its destination, it will rupture and kill everyone in the vicinity.
  • Standing near the Power Core will move it forward. This will drain your Shield, so use resources wisely.
  • Any damage it takes during the fighting will only hasten its destruction.


- Once you have successfully completed your mission, the Cipher will be consumed.

- To re-play the Mission, craft a new Cipher using your Blueprint and the necessary resources.


Tethra's Doom is on now and will end at 12 PM EDT on Wednesday, March 12.


Upon completing each mission, you will be scored as follows:

Individual Scoring - The core's remaining health is your score.

Clan Scoring - Clan scores will be determined by the sum of each participant's best score.

Yeah, I am looking to get a team running to get this sorted for me tonight - have a pair of keys ready to go, should be easy enough with a clan group, I hope :)

Got it sorted, thanks to some awesome clan support :)

(The hardmode one was easier than I expected though, pretty short mission.)

@mnemoidian: Glad to see you managed to get the reward =) It's a really simple event with a good team. On one hand it ended too soon, but the other hand I really dislike the quest designed around grinding. The events are getting better overall though.
