Level 4

I can't get the red card. I opened the only door I can, got the super shotty, killed everything, and now I'm stuck. The only other door that will open is locked because I need teh red card.

Find the switch on the pillar behind the bars. It is down the other passage from where the card is.
You cannot push this switch, you MUST SHOOT IT.

There are only a few switches in all of Doom and FreeDoom that have
to be SHOT and this is one of them. I am not fond of them, either, for various reasons that have to do with how it affects gameplay, and how
hard it is to realize that shooting can activate switches.

There is no other solution.
