Hey Serfinus!
This looks really interesting and is an awesome first step.
Since the Dom3 section of Shrapnel's forum is set to expire fairly soon (November was it?), you may want to move over either to the
Desura Dom4 forums or the
Dom3mods forums (it's now Dom4, but the site admin just hasn't changed the URL).
The Desura forums are official, and the Dom3mods one hosts a lot more of the modding work -- definitely check there for modding help and stuff.
I love those little wormy guys. I hope to see this nation developed!
