As you probably know, I downloaded the full versions of Doom and Wolfenstein 3D a couple days ago. Well, now I'm dead stuck on both games. Here's what I need help on:

Wolfenstein 3D: Level 7 - Episode 4: There's a locked door in the first room of this level, but I can't find the key to it. Where is it?

Doom: Epsiode 3 - Unholy Cathedral: I can't get the blue key. I know that I need to press a switch by a crushing pillar, but the platform is too high.

Thanks in advance.
