plesk game server module

[manodrum@]

Hi,

I have the game server module license added in Plesk, and the description from plesk is "...Using Plesk Module API, you can run virtually any game on your current Plesk server. The module includes Counter-Strike Game Server and Battlefield 2 Game Server..."

I see the counter-strike and battlefield icons, but how do I add more games since it says it can run virtually any game?

I'm interested in adding halflife 2, and other mods for halflife 1 like firearms.

Thanks,
Stephen
