3D Mud Client

Quark is an open source tool for making maps such as a town.

It is mainly designed for building maps for games like Quake but has been modified to compile maps using an open source map compiler called openbsp. The openbsp maps can be loaded into the mud client. Quark is included in the mud client package.

The official Quark site is at:
