The XET mod demo is ready for download at Fileplant. In case you don't know what XET is, here is a little description:
The demo will contain only the first two chapters from XET, WELCOME TO XET and FIRST ENCOUNTERS. Unlike a few mod demos, it will contain the first few maps of XET, so when the Full version comes out, you'll already know what will happen at the beginning...
Also there will hopefully be more than Fileplanet in the near future. For more updates on download URLs, go to Geocities.com
Finally, in the near future there will also be a demo map for download with some of the new monsters in it.
