This room is initially composed of a large main hallway, with two looping hallways hidden off to the sides. The center of the main hallway has a room which contains two Thumper Death Orbs, along with multiple Laser Plates firing at odd angles. Shoot one of the plates in the upper part of this room just above the central doorways, and a small pillar in the middle of the room will start to rise toward a grate on the roof, starting the test. Two doors will open on the sides just outside the Thumper/Laser room on opposite sides, leading to the hidden looping hallways. Go through one of the opened side doors, and step on the pressure plate in front of some gold doors. Get ready to move as soon as the doors open.
One hallway contains ice floor hazards (some of the ice hazards may appear glitched, but their effects are still present) and rising pillars. At certain intervals in the hallway, fast-closing and opening doors will attempt to shut you out from reaching the end of the hallway within the time limit. The optimal strategy for getting through is Bullet Jumping, and being mindful of the rising pillars that will try and block your path. Aiming your Bullet Jump high enough will let you ignore most of the pillars and frigid floor.
The other hallway contains multiple Thumper Death Orbs, along with the same fast-closing/opening doors. Using a Warframe that can ignore their slams (e.g. Rhino, Valkyr, Atlas) can make this hallway trivial to complete. Otherwise, alternating between Bullet Jumps and sprinting with good timing will get you through as well. You can also shoot the thumper's moving section to disable them.
At the end of each hallway is a plate above a door that you must shoot; but the shot itself will only register if you exit the small passage at the end of the hallway, before all doorways close the first time. Shooting both plates will extend the pillar to its full height and open the grate at the top, completing the test and rewarding you with Speed Drift.
When you're in the main hallway, try to avoid triggering Syndicate radial effects or using Warframe abilities that can damage things without needing line-of-sight, as they can hit the plates too early and fail the test.
This test can be run any number of times until completion. Should you fail any part, after a few moments you will be automatically teleported to the start of the hallway you failed to complete, provided you remained in the hallway (including the area between the exit and plate). Once a part is done (whether the Thumper or the Ice hazard one), it will be registered and saved as completed. This means you repeat one till completion, then do the other, without fear of having to do the first one again in case of failure.
As of 26th march 2017, this room is likely to spawn in the Exterminate mission Plato.
