Hi people, and sorry for post ... i'm french.
Here is the project I am currently doing: Last Escape
You are detained in a vast network of rooms and corridors where people there are very strange people ... each level will be an underground network, the last one will be outside (castle), I think to 6 levels.

The general mapping is finished, it needs to be done as furniture and scripting (enemies, items, weapons, ...) and of course the effects (ligthmap / shaders).
