Submerged deep below Uranus’ oceanic surface, and hidden from prying eyes, is a research facility for cloning and reproduction. Water pressure at these extreme depths put massive strain on the glass and steel structures housing these operations, but as freshly sprung leaks remind of the impending crushing force surrounding them, the Grineer forge ahead with their experiments.
—Uranus Fragment
Uranus is a planet where the Grineer are the controlling faction.
Uranus becomes accessible by defeating the Specter in the Uranus Junction on Saturn after completing the required tasks.
The Assassination Target of the planet is the scientist Tyl Regor, who is located at the mission node Titania. Tyl Regor drops the component blueprints for the parts of the EquinoxWarframe. Like all bosses, he has a higher than average chance to drop the relevant planet's rare resource – in this instance, Gallium.
Uranus features the Grineer SealabTileset as its primary environment, Submersible Archwing mode, and the ability to change between ground combat and Archwing gameplay in a mission.
Invasion Missions: The Corpus will appear as a "Assisting or Opposing" faction while the Infested will always appear as an "Opposing" faction during Invasion missions.
Spy Missions: Special enemy variants have a chance of spawning during Spy missions.
Survival Missions: The following lists below do not apply to Survival missions.
Oculyst spawns are common around the Desdemona sector, giving easier access to the Natah quest.
Uranus missions are one of the only locations where you can use Archguns against standard ground troops without installing a Gravimag; while underwater but close to the surface, you can fire up and out of the water hitting enemies on the ground platforms, and the Archguns will be at their full space-grade strength (some like the Velocitus are normally notably weakened when used in atmosphere). Conversely, you cannot fire standard weapons into the water to hit submerged enemies, the shots get stopped at the water's surface.
Any Grineer Sealab mission can drop Tellurium, making them an extremely efficient alternative to pure Archwing missions with a Warframe such as Nekros who can create more drops.
This is also more efficient if the player's Archwing is weaker than their ground combat potential.
During Exterminate missions it may be a good idea to keep the alarms going once triggered. With normal spawns stopping at about 140 enemies in, it will save you quite a bit of backtracking.
Notes[]
Uranus is currently the only planet to feature the Grineer Sealab tileset with the Submersible Archwing mode and one of only two planets to feature the tileset, with Earth being the other one, using the tileset on the Mariana node.
Brutus is an exception, as while Shakepspeare's play Julius Caesar does feature Marcus Junius Brutus as a character, neither he nor any character in that play has been used as name for Uranus's moons.
Uranus has special enemies that spawn in Grineer Sealabs that have "Drekar" before their respective unit name.
Another node on this planet formerly shared its name with the Oberon Warframe.
Uranus is theorized to have a layer with a liquid surface near the mantle. Unlike the depiction in Warframe, this ocean is predominantly made up of methane and ammonia, rather than water. Traces of water may exist, albeit in a superionic state. The pressure around this layer would be impossible to survive without proper equipment. This may explain Hunhow's limited ability to interact with the rest of the Origin System as while he can certainly survive the crushing pressures at such a depth, he is unable to move.
