From my unfinished Fade guide.

Movement: Being able to move around effectively and efficiently is the most important to learn. Many fade deaths are from getting stuck on objects or marines, and most of the time it’s the fades own fault.

As we know the fade is all about blink. Blink allows the fade to become the ultimate hit and run combat unit and any fade who wants to stay alive must master it. When you hit your +movement key you will gain speed based on how long you had your key pressed down. Going from a dead stop to max speed will require a longer key press than going from blink to blink. (max speed for the fade is 720 units without celerity and 945 with it. To see speed type cl_showspeed 1 in the console with sv_cheats set to 1 on your own lan server)

Blinking from a dead stop to max speed takes a keypress of a little less than a second. From blink to blink you will want to use less of a keypress because you wont require as much speed to get back to the max. For a comparison the blink for a dead stop would be like firing 5 bullets from your LMG. Blinking when you already have speed would be like shooting 1-2 bullets.

Another method of blinking is repeatedly tapping your blink key from when you leave the ground to when you hit it(when you stop tapping.) This will give you a greater distance traveled through the air. The cost of doing this is it drains your adrenaline bar more than the single tap blink. This method can be useful for escaping rooms quickly, blinking to higher platforms, blinking into vents, and catching jetpackers. Personally I like using this method when in combat with marines and will use the single tap blink for traveling around the map.

The starting direction you blink is based off where the center of your screen is looking. Looking up will make you blink higher in the air, looking down at the ground will make you blink into the floor. Generally it’s a good idea to look slightly up because you will blink further with the extra height. Also getting a little height on your blinks can avoid blocks from gorges and skulks.

Moving around mid-blink is the combination of two things, your strafe keys and mouse look. To do this correctly you will not use your forward key. For simplicity sake +moveleft is going to be bound to “a” and +moveright is bound to “d.” To turn left mid blink you would press your “a” key and move your mouse left. The severity of the turn is going to be based off how far you moved your mouse left. The same thing is done to move right but with the “d” key and moving the mouse right. If you do this correctly you should be able to navigate 90° corners with one blink. With some fast fingers it is also possible to zigzag left and right in one blink. The only use of the forward key for a fade is running on the ground so don’t hold it down when blinking.

The back key will make you lose speed dramatically. It is useful if your going to over blink a ledge or if you hit the top of a doorway and want to get back to the ground quickly.
