A Heretical Christmas

*sigh*

I've gotta release my 3 episodes soon.

That's not the only thing you should release.

What's a .gwa file? It was in the zip with the wad.

It's what you say when you see an extra file in the zip. Gwa!? :)

.gwa is for use with true-3D Doom engines, IIRC. It contains three-dimensional BSP data for use in engines like EDGE, JDoom, and Legacy.

... and Vavoom. But... who uses Vavoom?

Yah, well, these would be easier since about the last time I worked on them was 1997 and they're totally vanilla-compatible.
