EDIT: Never mind. I finally found out how to do it. The most absurd and frustrating switch and shield combination I've ever come across in a Doom map and I've played hundreds. 0/10 logical decision, stick to your real life job.

It's an absurd and completely illogical choice that goes against the Doom principle. If you don't time something right you should be able to retry again instantly, not having to start the map all over again. Frankly the switch should've simply lowered the shield. I stopped playing the WAD because of this unbeatable ending. It takes the joy out of playing.

There is a critical bug in MAP54 : Spider Testament by @alexsa2015sa. At the end, one of the 4 switches lifts up instead of lowers down a shield that is blocking the teleport to the exit. This makes it impossible to exit the map in a normal fashion.
