Cyberdreams: Level 30

I downloaded the Cyberdreams megawad, and I made it all the way to level 30. Once I arrive there however, I cannot complete the game. Does anyone know how to beat this level?

Thanks in advance to anyone who answers.

What exactly do you mean you can't beat the game? Errors? No skill? Please, clarify.

You could watch a demo to see how it is done (ftp).

why couldn't you beat it?

I don't get any errors, or the game doesn't crash. I simply don't know the strategy for beating the level. Also, please post your answer here on the bulletin board because I don't know how to get .cyds to work.

They're not .cyd:s, they're .cyb:s.. And they work exactly like .lmp:s.

Look, download this.
Put it in your PrBoom folder. Unzip it. The relevant demo is cy30-uv.cyb. RENAME this to cy30-uv.lmp. Now PrBoom won't have any problems with it. So next, type:

prboom -file cyber110.wad -deh cyber110.deh -playdemo cy30-uv

And enjoy.

Note that if the .deh and .wad are placed in another folder you have to specify the path to that folder after the -file and -deh, respectively.
