cant complete the mission cause the puzzle doors close to fast before i can even reach the end.

Its quite difficult, but possible to time your run to succeed. I remember it taking many tries for me to accomplish.

[Datalor3]

I think you need to time your run by waiting a few seconds on the edge of the first door, after pushing the lever.

[ACRONYM]

You have to pull the switch twice, so before you run, wait by the first door for the switch to reset, then pull it again, then Shift sprint to the end.

[Turambar]

You only need wait for opening the whole doors then doors wont be closed

Does the door speed change with the difficulty setting, because it was super simple when I did it (I was playing on EASY, though). I remember it being harder.
