Overview[edit]
Synergy is a co-operative multiplayer mod for Half-Life 2, Lost Coast, Episode One, Episode Two, and SiN Episodes: Emergence. It also includes fan-made cooperative maps, as well as support for certain mods. It is available for download on Steam.
Synergy has been in active development since early 2005; the first release was in September 2005. Synergy stemmed from two older mods, Dev Coop and DC Cooperative 2. The latter has been around since 2003.[1]

It also has the ability to mount other third-party mods (and games), as well as featuring separate co-op maps. Other features include: a soundscript loader, map configuration files[3] and Steam Workshop support.
