Synergy is a Half-Life 2 co-opertive multiplayer modification. We have evolved from multiple mods (DC Co-op 2, Dev Co-op and Tim-Coop) to offer you the greatest co-op experience. This modification strives to give Half-Life players a true Half-Life 2 cooperative experience. The mod features our own levels and the ability to play the Half-Life 2, Episode One and Episode Two campaigns co-operatively. In addition, you can add more content by installing third-party mods, such as ROCK 24 and MINERVA: Metastasis, then playing them in Synergy!

Synergy Release 1.0 will be available to the public on December 7, 2007!

Posted by VOSK on Dec 2nd, 2007

Our first release (Synergy Release 1.0) not in a testing stage will finally be released this Friday - December 7th, 2007!
This version allows you to play through the entire Half-Life 2 campaign, as well as the Lost Coast (if you mount it).

We've also removed the Half-Life 2: Deathmatch dependancy, so all you need to own is Half-Life 2 to play Synergy.
The Mega PhysCannon has been added in again.  Also, many other smaller improvements have been made; all of which can be viewed on our Development Page.

Here is some new Media:

You will indeed. That will come soon after tomorrow's release (give it a month or two).

Episode 2 however, will take longer (still waiting on Valve's SDK update).
