This guide will let you know how to find the Cephalon Fragments on Mars (Phobos Junction) in Warframe.
The first thing you need to do is equip your codex scanner. Choose gear, equipment or buy it first if you haven’t it is very cheap.
Having the thief’s wit or loot collector mode for your Warframe helps a lot, as it will show the cephalon fragment on your map.
Also, if you have the animal instinct mod, equip it on your companion.
The fragments spawn in almost every normal mission.
Captures are the best choice since you can finish them quickly after scanning or finish it and then search for them.
If you don’t already know, the fragments look like every mission has one, located randomly.
As you can see on the map, the blue icon is the cephalon fragment; it only shows up if you have the mods mentioned before.
As you can see, it is very fast, be sure to check around the map.
If you still can’t find it, try restarting the map and hope it has a better spawning location. You have to hold “Q” to open the gear hotkey and select the codec scanner; once equipped, click and hold while looking at the fragment.
