[MDL ED] Making A Monster

[hunchbackproduction]

There are very few tutorials, video or text written, out there about how to make a monster and put it into amnesia.
I just have a few questions, I think I can figure out the rest by myself.

1) Is it possible to completely make a monster in blender, or must I use maya ?

2) Is it easier to make from scratch, or can I just tweak and retexture the already existing amnesia monster eg: brute?

3) *Noob Question xD* How do I make monster animations ? Is it in the amnesia model editor program or the other program, like maya. Can blender sucessfully make these animations ?

Sorry If this has already been covered but it's pretty hard to find. Not many guides xD A start to finish guide would be nice, detailing every step :3
