Another 5D offering from the world's only fisheye aficionado. This one is a small room with 4 pillars... 4 times. Confused? Try playing. And beware... he's shooting for 8 layers.
A 17-level nethop map with a seriously cool intro level. Most of the individual levels have been released in some form... many have changed pretty radically, though. Get this map for its grandeur alone.
