Is Synergy Standalone? (Plus some other questions)

[_galaxy]

Hi, I would like to ask is synergy standalone? Plus I want to mount content on some games, how do I do that?

Synergy requires Half-Life: 2, and it also wouldn't be a bad idea to get Half-Life 2: Episode 1 and Half-Life 2 Episode 2 as some base Synergy maps mount this content, but you'll be able to play all of Half-Life 2 and some other maps with just Half-Life 2.

All content Synergy supports by default is mounted automatically, adding adding additional content will either require custom mounts on both client and server or forcing clients to download content from the server.
