The Grineer Sealab is a planetside tileset introduced in Update 16.5 with the Operation: Tubemen of Regor event, and is the default planetside tileset for Uranus. Taking place on a Grineer underwater research facility, this tileset features both artificial structures intermixed with oceanic strata and views of the ocean. It also features vast underwater areas which have to be traversed using Archwings, allowing for three-dimensional submarine combat. Nodes that contain the tag Submersible will feature said underwater areas, and cannot be entered if a player has no Archwing equipped.
This tileset can also be found on Earth as a secondary planetary environment, but Archwings cannot be used in water areas.
- This tileset features advanced versions of normal Grineer units, all with the 'Drekar' prefix. Drekar enemies tend to be similar in stats compared to their normal variants, aside from occasional units having slightly more health or armor. Manic Bombards appear on this tileset when assassinating Tyl Regor, which are the most significantly unique and dangerous enemy on this tileset besides the underwater ones.
- Underwater enemies include Grineer wearing large diving suits, in addition to giant bombs and sharks called Lanx. These sharks will attack Tenno and Grineer alike and follow a predictable pattern, entering or exiting inaccessible holes in the reef. They inflict a guaranteed proc when hitting the player, easily bleeding out players with low health who aren't careful to avoid them or kill them first.
- This is the first tileset where players can encounter Sentient enemies called Oculyst. These mysterious drones randomly appear in missions and are invulnerable to damage.
Similar to the Orokin Derelict tileset, certain tiles can feature flooded rooms with electricity charging through the water, which slowly deals damage to any units that stand upon it with a chance to proc. The electric current can be turned off by deactivating a large power console within the room.
In certain rooms, gears will be exposed from the floor, spinning rapidly as they work. Standing on the gear not only flings the player in a given direction but also inflicts damage; the slash damage may not seem lethal, but caution should still be taken. A small bridge is always available to avoid touching the gears, although jumping over is another method.
Found on underwater segments, these natural vents, seen as conical bumps on walls with large yellow craters, will periodically eject high-speed water jets that can deal damage to passing players. Larger vents can be found directly underneath large pools of water that serve as entry points into underwater levels, which can eject large volumes of water up the pool; players caught in said eruptions while underwater will be forcefully ejected out onto dry land.
These large, red mines can randomly appear in any location while underwater, and will detonate upon contact with players, dealing damage and proc within a small radius. These mines can be destroyed by using weapon attacks or Archwing abilities.

- One of the tiles feature bunkrooms with interactive shower pods that spray water upon activation. This feature is purely cosmetic.
- An Ogma can be seen parked in the extraction tile, indicating that said unit can be used underwater.
- One of the dead-end tiles has an Orokin Death Orb under disassembly, possibly indicating that the Grineer might be attempting to reverse-engineer it.
- This is the same tileset featured in the Tomb of the Sentients trailer.
- This is the first tileset that can switch between normal ground-based gameplay and Archwing mechanics in the same mission outside of quests.
- One of the rooms displays Tubemen in different stages of infestation being studied by strange two-headed cybernetic research drones augmented similarly to Councilor Vay Hek. This suggests that Tyl Regor has access to the infestation.
- Orokin structures and Sentient bodies can be found outside the lab, generally buried in rock or submerged. Most notably, a crashed Orokin ship being excavated by a Grineer submarine is located in the center of one of the underwater segments, and the remains of the massive Sentient Hunhow can be seen in the distance on an Archwing extraction tile.
- There is a bug in which a player can clip through one of the Grineer storage lockers against the wall and enter the inside of the map.
- Sometimes when attempting to exit Archwing a player will still have their Archwing equipped and be unable to move.
- If the rescue target happens to fall in the water there is a chance they will disappear and the mission will be a failure. This also happens to the Syndicate Operatives in Syndicate Alerts, as they will die immediately upon touching the water.
- In the short hallway connector Tile, it is possible to hop outside the railing of the walkway and use slide to hide under the walkway. if you move around too much down there you can fall outside of the hallway through some of the fake walls and be stuck inside the map. Although it is still possible, if the "unstuck" command doesn't work, to get back in with some given effort and Bullet Jumps.
- On PS4 the Tubemen that are part of the map and the Grineer working on them all have missing blacked out faces.
- On the tile with the dismantled Orokin Void Death Orb, you can leave the map (consistently) by going to a ledge underwater and entering a crack on the wall.
- Operation Tubemen of Regor, which introduced this tileset.
- Docking Bay, the Conclave map which uses this tileset.
