Doom 64 level 2, The Terraformer: Keys and exit
39Shows how to reach all keys and the exit in Doom 64 level 2, The Terraformer. Enable Captions for on-screen notes, and read below for a walkthrough of the blue-key room, followed by details on Running, a useful ability in the game.

ABOUT THE BLUE KEY ROOM
When you first find the blue key, it will be resting on a short pedestal in the center of the room. On the back of the pedestal is a switch. Activate it to lower the pedestal. When you then attempt to grab the blue key, it disappears.
(Note: For an example of an exploit that allows the player to grab the blue key directly from the center pedestal, see https://youtu.be/OpByxFBxPqE and the video description there.)
The blue key will then pop in and out of existence along the tops of the other pedestals in the corners of the room. Eventually the key comes to rest on one of them (the final pedestal is chosen at random). When this happens, 4 doors open up along the back of the room, and behind each of these doors is a switch. To either side of 3 of these 4 switches are short vertical slabs rising out of the floor. Go to the one switch where those slabs are missing.
When you activate this switch, the pedestal where the blue key now rests will drop. Run (remember your 'Speed' or 'Run' button) to the pedestal before it rises again.
A useful alternative to plain running is to use a simultaneous combination of Run-forward plus Strafe-sideways. This 'Strafe Running' method will move the player character at an odd angle, but at a speed slightly faster than normal running. (See https://youtu.be/PP90OPiemIk for a video demonstration of movement speeds in Doom 64, and see below for additional details about Running controls in various versions of the game.)
If the pedestal rises up before you grab the blue key, just go back to the switch and try again.
If you activate any of the 3 switches that have those slabs to either side, part of the ceiling overhead will briefly drop and crush you, possibly killing you if your health is low.
See https://youtu.be/yRejU7Xn3LY for another example of the blue-key puzzle.

ABOUT 'RUNNING' IN DOOM 64
In all classic Doom games, the player character can walk or run. In the original N64 game, the default Run button (named 'Speed') was the left-most of the 4 yellow 'C' buttons on the right half of the N64 controller.
All Doom 64 games or modern ports allow controller buttons or keyboard keys to be assigned/re-assigned to different functions. 'Run' or other functions can be checked or (re)assigned by first opening the game's Main menu, then:
In N64 Doom 64: Options - Control Pad - Speed
In the 2020 Doom 64 ports: Options - Input - Bindings - Speed
In Doom64 EX: Options - Controls - Bindings - Run
NOTE: Some of the Doom 64 ports or conversions above also have a separate 'Autorun' (automatic, continuous run) function. In such games, if Autorun is already On at any given time, then activating Run/Speed at the same time will actually slow you down to walking speed.
Note that the original N64 game will not preserve changes to controller layout (or any other user-configurable settings) once the N64 is reset or powered down.
