How do I leave the Plains of Eidolon?

I have gotten lost out in the Plains of Eidolon. How can I leave without losing progress?

Solution 1:

Option #1: The Ostron Tower:

(in the background slightly right of the targeting reticle)

This tower will always be visible in some part of the skybox while out in the Plains, and will always lead you to the edge of Cetus (though not necessarily to the door).

Option #2: The map.

There is a setting in esc->options->interface called "Lock Map Rotation" (LMR).

Once back out of the options, press "M" to bring up the full-size map.

If LMR is ON:

• Cetus will always be in the center of the extreme south side of the map.

If LMR is OFF:

• Look for a large gray blob in the center of a side of the map. This is Cetus. It is possible that Cetus does not appear on the map where you are. In this case, try to have your Warframe look around in different directions, as this will rotate the map and hopefully give you some idea of where Cetus is.

Option #3: Aborting.

Go to esc->abort mission. Unlike most other missions in the game, here you get another menu asking if you wish to return to Cetus or to your orbiter.

It is uncertain whether method #3 retains the drops from the session or not. Use at your own risk!
