Workshop Maps

# Get a Steam Web API key from steamcommunity.com/dev/apikey
# Add to launch options:
# +host_workshop_collection COLLECTION_ID
# +workshop_start_map MAP_ID

# Create a map cycle with workshop maps
# gamemodes_server.txt can reference workshop maps

Best Practices

• Use 128-tick rate for competitive play
• Set up auto-update via cron with SteamCMD
• Configure GOTV for match recording
• Use server plugins like MetaMod/CounterStrikeSharp for customization
