Tutorial for ep2 citadel?

Title says it all.
How do you create them in your own map?

The Ep2 Citadel?

Which bits do you want? The collapsed structure, the superportal, what?

I think he means the collapsed structure with the super portal funneling out of it.

Well the structure is just a flat prop_static, but as for the superportal… Particle effect? Prop_dynamic? I dunno.

Try decompiling one of the maps with it in, to see how the entities are set up.
