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 (Orange Box) will be released on Friday, August 15, 2008!

Posted by VOSK on Aug 10th, 2008

UPDATE: unfortunately for me to say, we are not ready for release. There's been a misunderstanding on our part, and we need to post-pone the release. Sorry guys, I know you were looking forward to it.

I believe Sven Coop 2 will be close to same as Sven Coop 1, that means SC2 will also be awesome. But Synergy is a strong choice and Folo freeman.

Grats on Steamworks, definitely deserved for you guys :)
Can't wait to see which other mods were offered Steamworks as well. Valve have taken another great step forward in embracing the modding community with this.
Looking forward to an update with stats and achievements :)

All you need is Half-Life 2. But to play Episode 1 and Episode 2, you'll obviously need to own those.

The mod would require a source game with an access to the "Source SDK Base - Orange Box" tool.

HL2 (the original game) and all source games give you access to the Source SDK Base - OB. We (ZP:S Team) had to test this awhile back when we moved over to the OB SDK. If regular HL2 owners couldn't play we'd never have upgraded.

Awesome. I just hope they fix all the single players bugs. What I mean by that is that in Synergy nothing that single player based Ever worked, no beginning cinematics, no animations. One example is that when the player falls through the stairs and gets jumped by the combine in the beginning of Hl2 Alex kicks their rear ends and helps you up. I thought that was one of the coolest parts of Hl2 but nobody even sees that in Synergy. I hope you guys fix all of that stuff.

One solution could be to temporarily focus everyones camera on the trigger players camera.
