here is WIP (work in progress) of my level : The Pyramid of Khaos
It is far from finished.  But I cannot stand to publish a map!
Most of all, I have to change the name.

It is a Single player match map, but I am going to change this soon.
Actually, there is not a lot of monsters in the level...
It is just version alpha 0.001a  (you know what I mean)

Here is the scenario :

A strange alien Pyramid (actually a conic shape) has landed on the
space platform Lunar 7b.  Lunar 7b is a platform with a huge pool used 
to test some very weird and dangerous fish species in a space 
environment.  
This platform is in orbit around the moon.  There is also an alien 
spaceship in orbit around the platform.  It seems that there are no way
to enter this spaceship.
You are sent with the space shuttle to the moon and your mission 
is to explore the pyramid and eventually find a way to 
enter the spaceship... and find the secret.
Beware (in multi player games) the russians have sent Soyouz 14 to 
explore the pyramid too...

Be careful.  It appeared that some species in the pool have 
muted... (not really, because I still have to put monsters in 
the level)
And we don't know what you will find inside the pyramid.
