I recently put a lot of work into cleaning-up our three (3) Counter-Strike 1.6 (CS1) 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 Quake-Sounds system (kill-steaks sounds, event sounds, etc.)
  
• Implementing some additional fun mods (weapon-fire tracers, 3rd-person camera view, chicken-mod, player-blocking prevention, back-weapons, etc.)

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

• Cartoon-Strike! (details) - a non-serious / "fun" type CS1 server.
  
• Boomer-Strike! (details) - a very conventional / old-school CS1 server.
  
• Unfriendly-Fire! (details) - a friendly-fire / 24x7 "Assault" CS1 server.
