Help with game creation

[Tottel]

Hi and welcome to the forums.

What exactly are you asking: That we explain it to you, or that we do it for you?
In any case, I would suggest you to learn it.

Scripting:
I would suggest you start with this, http://wiki.frictionalgames.com/hpl2/tut...y_tutorial
and continue through it; it's not so hard to understand, and you should be able to make some cool stuff fairly soon.

Custom models:
You don't know how to export models, but do you know how to model? If not, why not make a map with the models and textures that are available to you?
On the other hand, if you DO know, then this should help you a bit getting on track: http://wiki.frictionalgames.com/hpl2/tut...loutsource

P.S. The map is looking pretty nice from what I've seen so far. Good luck.
