I recently put a lot of work into cleaning-up our three (3) Half-Life (Hl1) dedicated game-servers. This included work such as:

• Cleaning-up/removing old/broken stuff.
  
• Troublshooting/fixing downloads of custom stuff (sounds, weapon models, player models, etc.)
  
• Implementing a new sounds system (kill-steaks sounds, event sounds, etc.)
  
• Implementing some additional fun mods (UT-style floating/spinning weapons, etc.)

Below is a link to the details for each server setup:

• Teletubbie Civil War! (details) - Teletubbie player models, sounds, etc.
  
• Spirit-of-Christmas! (details) - Jesus and Santa player models, SoXMas-sounds, etc.
