How to build a warframe railjack - rising tide quest guide

Railjacks arrived in Warframe with Update 26.1, Rising Tide. The Railjack is a full-size battleship that takes part in ship-to-ship battles, requires a full crew and houses a brand new Cephalon. The Railjack is built and housed in a Dojo Clan Dry Dock and can be upgraded with mods, new weapons, and cosmetics.

The first step in building your Railjack is to build a dry dock in your Dojo clan. After that you will need to research and build Cephalon Cy. Once these two stages are completed and the quest for The Second Dream completed, you will have access to your Codex's Rising Tide quest.

Click the "Get Started" button at the bottom right of the screen. Cephalon Cy will ask you to take it to the Dry Dock and set it up there. Just go to your Dojo and follow the waypoint.

When Cephalon Cy is installed, it will tell you that in order to build the Railjack you need to research the Ancient Coins. It will then show you the location of the first part.

Step 1 - The fuselage

Cephalon Cy will send you to Mars to find the fuselage. Just go to your navigation screen, click on Mars and the mission will be clearly marked on a node. This mission is very simple: go to the marker and interact with the fuselage to start scanning it. You must keep the area clear of any enemy, as they will interrupt the scan if they get too close. Two sensitive drones will arrive which will block the scanner, so kill them and the scan can resume. When it's done, head to the extraction.

Cephalon Cy will ask you to go to the dry dock. Join the Dojo and Fast Travel there. The fuselage needs to be repaired and you will need The res
