Zealot Derelicts have started to appear in Warframe as part of Nightwave Series 2. Arlo is clearly up to something, and all good Tenno need to try and stop him. To do so, you will need a Zealot Derelict Code. These will give you access to the Derelict, and whatever mission that they contain. Keep in mind, you will not be able to join the mission at all if you do not have a code, and you will not be able to get piggyback from someone who does. All members of a squad must have a code to be able to start the mission.
Warframe – How To Get A Zealot Derelict Code
Getting a Zealot Derelict Code is very simple; it is just a little bit ambiguous in the game. What you need to do is complete Infested Outbreak Invasion missions. If you look at your Navigation screen, you will see a small counter above the Nightwave button that will tell you how many Infested Invasions are active, and what planets they are located on. This will only appear if there are active Derelicts on the Star Chart.
Just go to the planet, then look for the Invasion icon on the nodes. Alternatively, you can click the Invasions tab in the upper right-hand corner of the screen, and select the mission from there.
Like all Invasions, you need to complete the mission three times to secure your Battle Pay, which is a Zealot Derelict Code. Once you have the code, you can access the mission, complete it, and get your rewards. The Derelict can be found on a new node, in orbit around the planet where the Invasions are taking place, as shown in the image above.
