A question for the Doom experts

[Drev]

I have played this game for so long, and I never was able to enter the secret level in Episode 1 the legit way. How do I do it?

[Drev]

Nvermind I figured it out.

Close this.

You have stumped me with your question. I used to know every secret of every level, but I have forgotten them all.

Curse my old brain.

Right now the only doom I have is "Final Doom" but I could never find out where the heck the "spider master mind" boss was hidden...If anyone could help it would be appreciated.

There are bugs in Final Doom that prevent you from passing some of the levels without cheating.

At least, it didnt' work for me.

[Drev]

I can't beat the final boss in doom 2 without cheating.

I know what to do, but I miss the platfrom at the last split-second.
