Nethack is a complex hack and slay game, and is known since the first personal computer age. Nethack goes 3D. After working on irrhack (a 2D Nethack graphic interface) i transfered this into 3D graphic (the irrlicht engine makes it possible).
It is possible to attach and modify 3D models and sounds via xml files.
Wow, this is visually amazing. You actually move! As in, you walk instead of teleporting from square to square. A huge step forward. I don't suppose it's possible to zoom in/out? I guess that would be asking too much.
