Support for SourceMod and custom maps, included on every GGameHost Contagion plan.
Your friends or community to play with (up to 16 slots).
Step 1 — Choose your plan
Pick a plan sized for your Contagion community. We recommend about 512 MB–2 GB of RAM; start smaller and upgrade in one click as you add players or mods. Contagion plans start at $10.99/mo.
Step 2 — Deploy your server
Check out and your Contagion server provisions automatically in under 60 seconds, with console access right away — no manual install, no command line.
Step 3 — Connect & invite players
Once your Contagion server is online, copy its address (IP and port) from the panel. Your players open the console with ~ and type connect <address> — or add it under Favourites in the server browser. Start, stop and restart it anytime from the control panel.
Step 4 — Install mods & configure
Your Contagion server supports SourceMod, Custom maps, FTP/SFTP. Install SourceMod and custom maps straight from the one-click installer, or upload your own from the control panel — then tweak settings in the visual config editor.
Step 5 — Keep it running smoothly
Enable scheduled automatic backups, set restart timers, and monitor CPU, RAM and player counts from the dashboard. Always-on DDoS protection and 24/7 support keep your Contagion server stable.
