1. Acquire the dedicated server files

• download here: sourceds.rar
• or use the HLDSUpdateTool which can be found somewhere on www.steampowered.com

2. Copy your /hl2/ folder from steam/steamapps/username/half-life/hl2/ to sourceds/hl2

• Note: Make sure you have your half-life 2 gcf files extracted into your hl2 folder! You can extract the files from the half-life 2.gcf by using GCFScape.

3. Make a shortcut with a commandline that looks like this

• C:\sourceds\srcds.exe -game hl2 -maxplayers 128 +map hl2deathmatch -console

4. Run the shortcut and you have a hl2 dedicated server!
