(KAHN Internet Gaming Service)

Kahn is a network driver that allows people to play games on the internet that are normally limited to local networks. Each player connects to a Kahn server, and can then chat and play with the other people on the server. Kahn accomplishes this by setting up a virtual IPX network among players on the same server. Just about any game that uses either DOS IPX or Winsock IPX can be played successfully over Kahn.

http://w3.one.net/~billw/KPUD/
Warcraft II KPUD Home Page

What are the KPUD's ...
The KPUD's (for Kali and Kahn PUD's) will be a set of 'standard' PUD files to be used in multi-player games for Kali, Kahn, and Mac internet play. Their purpose is to extend the set of available PUD's for internet players and make that set available for free to everyone. In order for this concept to be successful, many players must participate by providing and using the KPUD's, helping choose which PUD's are part of KPUD collection, and spreading the word to all internet Warcraft II players.

Tip of the Week

Blizzard joins the discussion. As the title suggests, this is a place for tips. However, I have yet to see it change from week to week.

The City of WHAT!

Its already a long time ago since the human and orcs started off a bloody war. The war ended when it destroyed every thing, the warlords have no more resources and can no longer support their huge armies, peace came with a total destruction. Behind an uninhabited forest covered with the fog of war, there is a hidden city, it is probably the only human city which is not destroyed by the orcs. Someday, someone discovered the city, he reconstructed the abandoned place, and became the so called owner of the city. He is Dennis, and he named the place as The City of WHAT!
