== Development history ==
The Synergy mod grew from the merger of the Dev Coop and DC Coop 2 mod projects. In 2005, there were only three people working on Dev Coop without any real plans to release a public version. DC Coop 2 had around six active contributors and a mod called DC Coop. Since the first public release of Synergy (Beta 1.0) in September 2005, the team has continued to work on improvements, updates and features. 
While Synergy Beta 1.0 supported only the coop game mode, Beta 2.0 added support for Teamplay and Deathmatch game modes and many other custom features for level designers.
With Synergy 1.1, support was added for Episode One features, resources and maps, and shifted the codebase dependency to Source SDK Base and Half Life 2.
Synergy OB added support for Episode Two content and singleplayer, in this version Teamplay and Deathmatch and Scripted NPCs were removed.
In 2012 the Synergy Development Team returned to actively developing Synergy and released Synergy 2013 after months of development. Synergy 2013, the current version, is based on Source SDK 2013 and has many new features including support for the Oculus Rift and Mac and Linux versions of the mod, the mod also runs on Valve's console called Steam Machine, and unofficially also supports Steam Deck.
