Phobos

"The Grineer have occupied the abandoned settlements here."

- In-game description

 is a moon where the Grineer are the controlling faction.

The Phobos Nav Segment can be obtained by defeating General Sargas Ruk located on Tethys, Saturn.

The vital targets of the moon are Lieutenant Lech Kril and Captain Vor, who are located in the mission Iliad and where the blueprints for the Miter and its components, the Twin Gremlins and also the Trinity Warframe can be obtained. They also have a higher than average chance to drop Morphics each.

Phobos does not currently have a Tenno Relay player hub.

Enemies
''Infested and Corpus can appear during Invasion missions. The lists do not apply to Survival missions.'' During Spy 2.0 missions, special enemy variants may have a chance to spawn.

Tips

 * Phobos contains high drop rates of both Rubedo and Morphics.
 * Due to the level of Iliad, Vor is significantly more powerful on Phobos than he is on Mercury, but Kril is weaker than he is on Ceres.
 * Sentinels have a very slim chance of surviving during these levels as constant bombardments from Hellions can easily destroy them regardless of how durable they are.

Bugs

 * During the cinematic of Captain Vor & Lieutenant Lech Kril on Iliad, some players' screens go black, and they wouldn't be able to see what was happening in there.
 * Kril will often spawn partially inside the large spherical object on the top of the arena area, immobilizing him for the majority of the battle.

Trivia

 * Phobos is named after the Greek personification of fear and one of the sons of Ares, who is Mars' Greek equivalent. It has a twin moon called Deimos (strife), the latter currently is not available in Warframe and there are no plans on adding it.
 * In contrast to how Phobos is depicted in-game, in real life, it is irregular in shape. It is widely believed to be a captured asteroid.
 * The nodes on Phobos are named after actual named geological features of Phobos. Other than Monolith and Iliad, those in turn are named either after astronomers (e.g. Asaph Hall, who discovered Phobos) or after characters in Gulliver's Travels (as its author, Jonathan Swift, predicted the existence of Mars' moons).
 * The boss level, Iliad, is named after an ancient Greek epic poem, which tells of the battles and events during the weeks quarrel between the King Agamemnon and the Warrior Achilles.
 * This planet was unlocked as a reward for the community completing the Arid Fear Event. Much of the event involved the Grineer and the Corpus trying to hide Phobos' existence from the Tenno.
 * Up until The Gradivus Dilemma Phobos was the third planet in the game that was completely under the control of a given faction (besides the indigenous species), following the (then) Infested-controlled planets of Eris and Jupiter.
 * Phobos is the first planet to have an Assassination mission involving more than one entity, the second being the Hyena Pack on Neptune. The mission comes up as a "?" but shows a picture of Vor and Kril in the lobby. It is not known why it is marked as "?".
 * Looking into the distance from the extraction point one will be able to see what looks like a Fomorian ship on its side in the far background.
 * Phobos' geology appears to resemble Mars in reality, having red soil and a desert like environment.
 * Phobos is the only planet on which Research components do not drop.
